You append a name of category to variable called $cats.
But you never reset this variable. So every post appends its categories to the same variable.
So here’s how to fix this:
```
<?php
$categories = get_the_terms($custom_args->ID, 'veranstaltungen-category');
$cats = ''; // set empty string as value
foreach ($categories as $category) {
$cats .= $category->name . ', ';
echo rtrim($cats, ', ');
}
?>
```
Of course you can also add commas to your second code:
```
foreach ($categories as $i => $category) {
if ( $i ) echo ', ';
echo '<span>'.$category->name .'</span>';
}

] | everybody,
I have created a custom\_post\_type;
```
function create_post_type_veranstaltungen()
{
register_post_type('veranstaltungen', array(
'label' => __('Veranstaltungen'),
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_icon' => 'dashicons-admin-site-alt',
'supports' => array('thumbnail', 'title', 'editor', 'author',
'excerpt', 'comments'),
)
);
}
add_action('init', 'create_post_type_veranstaltungen');
```
with its own section of taxonomies
```
function tr_create_my_taxonomy()
{
register_taxonomy(
'veranstaltungen-category',
'veranstaltungen',
array(
'label' => __('Category'),
'rewrite' => array('slug' => 'veranstaltungen-category'),
'hierarchical' => true,
)
);
}
add_action('init', 'tr_create_my_taxonomy');
```
Then I created 4 post and I implemented the corresponding loop that works
```
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$custom_args = array(
'post_type' => 'veranstaltungen',
'orderby' => 'date',
'order' => 'DESC',
'paged' => $paged,
'posts_per_page' => '10'
);
$wp_query = new WP_Query($custom_args);
if (have_posts()) :
while (have_posts()) : the_post();
?>
<div class="pagination">
<?php
$big = 999999999; // need an unlikely integer
echo paginate_links(array(
base' => str_replace($big, '%#%', esc_url(get_pagenum_link($big))),
'format' => '?paged=%#%',
'current' => max(1, get_query_var('paged')),
'total' => $wp_query->max_num_pages
));
?>
</div>
```
if income posts\_per\_page => '-1' works, if I enter posts\_per\_page => '1' also works, but if I enter posts\_per\_page => '10' does not show anything at all.
Does anyone have an idea of what may be happening?

I am not comfortable storing those credentials in the Database because of the trouble you mentioned you could get into if they got out. Or putting them in a theme file. Like they mentioned in the other thread, if Apache gets screwed up and that files gets processed as plain text. Your credentials get exposed. If your DB is setup to only accept localhost connections or a specific IP, that could save you. But if your SMTP credentials get out, you might not have those luxuries.
If your setup looks like: (And your public website lives inside of public\_html)
```
/home/user/public_html/
\__ wp-config.php
```
I would store a file in: (Which is not public facing at all)
```
/home/user/smtp-connect.php
```
And then include() or require\_once() that `smtp-connect.php` file when you need it. Have your credentials stored in there and your connection script in there as well.
The article you referenced has some good points about locking up your wp-config file. Here is another article that I think could shed some more light on the security of wp-config.php and some work arounds to help secure it if you decide to setup some PHP Constants for your SMTP Credentials:

341,144 | <p>I created a Wordpress REST API custom endpoint to be used as a Webhook URL in WooCommerce in order to convert the received data and then send it to a third party system, but the endpoint apparently is not receiving any data. I tested the code by sending some JSON data to my custom endpoint using Postman and it works only after installing another P;ugin to enable Basic Auth. I wonder if the problem is because probably the webhook needs authentication in order to be able to POST the data to the same domain? If that would be the case I have no idea where to setup basic authentication in the Webhook setting in WooCommerce. </p>

$curl = curl_init();
switch ($method) {

The debugger tells me that get\_theme\_mod() is returning 'false', when I expect it to return the value of the selected item. Using get\_option() gives me the key of the option, "value3" and not the value.
I would prefer to use get\_theme\_mod() since that is what the function is for, but if I can't how do I get it to output 'American Typewriter' instead of "value3"?
**functions.php**
```
function lettra_customized_css()
{
?>
<style type='text/css'>
.site-title {
<?php
$foo = get_option('title_font'); // "value3"
$bar = get_theme_mod('title_font');// false
?>font-family: <?php echo get_theme_mod('title_font') ?>;
}
</style>
<?php
}
add_action('wp_head', 'lettra_customized_css');
```
**cutomizer.php**
```
function lettra_customize_register($wp_customize)
{
$wp_customize->add_section(
'font_options',
array(
'title' => __('Font Options', 'lettra'), //Visible title of section
'priority' => 20, //Determines what order this appears in
'capability' => 'edit_theme_options', //Capability needed to tweak
'description' => __('Choose font pairings for your theme here.', 'lettra'), //Descriptive tooltip
)
);
$wp_customize->add_setting('title_font', array(
'default' => 'Roboto Slab',
'capability' => 'edit_theme_options',
'type' => 'option',
'transport' => 'postMessage'
));
$wp_customize->add_control('title_font_control', array(
'label' => __('Title Font', 'lettra'),
'section' => 'font_options',
'settings' => 'title_font',
'type' => 'select',
'choices' => array(
'value1' => 'Roboto Slab',
'value2' => 'Times New Roman',
'value3' => 'American Typewriter',
),
));
}
add_action('customize_register', 'lettra_customize_register');

`get_theme_mod()` isn't working because when you registered the setting, you set the `type` to `option`:
```
$wp_customize->add_setting('title_font', array(
'default' => 'Roboto Slab',
'capability' => 'edit_theme_options',
'type' => 'option',
'transport' => 'postMessage'
));
```
The possible values for `type` when adding a setting are `'option'`, or the default, `'theme_mod'`.
`option` stores the value independently of the current theme, and is retrieved with `get_option()`, while `theme_mod` stores the value only for the current theme, and is retrieved with `get_theme_mod()`.
>
> Using get\_option() gives me the key of the option, "value3" and not the value.

The 'key' *is* the value. It's what's output into the `value=""` attribute of the `<option>` tag.
If you want to use the label, there's two potential solutions.
First, you could just pass the labels only, then these will also be used as the values:
```
array(
'Roboto Slab',
'Times New Roman',
'American Typewriter',
),
```
Or you could store a reference to the labels independently of both places:
```
function wpse_341193_get_font_options() {
return array(
'value1' => 'Roboto Slab',
'value2' => 'Times New Roman',
'value3' => 'American Typewriter',
);
}
```
Which you can then use as the choices:
```
'choices' => wpse_341193_get_font_options(),
```
And the output:
```
<?php
$font_options = wpse_341193_get_font_options();
$font_family = get_theme_mod('title_font');// false
?>font-family: <?php echo $font_options[$font_family] ?>;
``` |

John | First remove action of customizer then add your action with new function name.
**in your child-theme functions.php**
```
add_action( 'init', 'remove_my_action');
function remove_my_action() {
remove_action('customize_register', 'business_prime_settings_control',10);
}
require_once dirname( __FILE__ ) . '/inc/business-prime-customizer.php';
```
**in your child-theme/inc/business-prime-customizer.php**
**change name of function and callback**
```
function business_prime_settings_control_child($wp_customize) {
# here your all customizer settings code
}
add_action('customize_register', 'business_prime_settings_control_child');
```
Remove other extra actions and declared functions. otherwise you will get : Cannot redeclare Fatal error. |

] | When I try to upload a theme in my Wordpress website I need to fill in FTP credentials.
I've installed vsftpd on my Ubuntu 18.04 server. When I connect with the credentials in my FTP client (ex. Cyberduck on mac) I see the following:
[](https://i.stack.imgur.com/7Ps5B.png)
The problem is when I try this in Wordpress I get the error `FTP + Unable to locate WordPress content directory (wp-content).`. What could be the problem here? | * All files should be owned by the actual user's account, not the user account used for the httpd process.
* Group ownership is irrelevant unless there are specific group requirements for the web-server process permissions checking. This is not usually the case.
* All directories should be 755 or 750.
* All files should be 644 or 640. Exception: wp-config.php should be 440 or 400 to prevent other users on the server from reading it.
* No directories should ever be given 777, even upload directories. Since the PHP process is running as the owner of the files, it gets the owners permissions and - - can write to even a 755 directory.
You can use
```
chown www-data:www-data -R *
find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;
```
you can also trying the following
```
add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
define( 'FS_CHMOD_DIR', 0751 );
define('WP_TEMP_DIR', ABSPATH . 'wp-content/tmp');
```
The `tmp` folder wasn't having the permission and that caused the website plugins from updating. |

There are no WordPress APIs or WP based solutions that will do this. Instead you will need to use a general PHP solution inside your plugin, and should look at general PHP resources and communities, not WP ones.

341,471 | <p>I'm trying to create a nav menu with a clickable dropdown function but minimize scripting at the same time, so I found out a way to achieve this with an invisible input box and CSS. My only problem is I have no experience with PHP and getting the menu to load the right HTML is very frustrating (it took me forever just to get the custom walker to show up in the first place). This is the effect I want to achieve - the same default WordPress menu, but the menu items with children are slightly different:</p>
<pre><code><ul>
<li>A menu item</li>
<li>A menu item</li>
<li>
<input id="check-(item-id)" type="checkbox" />
<label for="check-(item-id)">A menu item with children</label>
<ul>
<li>Child one</li>
<li>Child two</li>
</li>
<li>A menu item</li>
</ul>
</code></pre>
<p>In my functions.php file, I have this:</p>
<pre><code><?php
/*---- Custom Menu Settings ----*/
function custom_menus() {
$locations = array(
"top-menu" => __( "Top Menu" ),
"side-menu" => __( "Side Menu" ),
);
register_nav_menus( $locations );
}
add_action( "init", "custom_menus" );
class Clickable_Dropdown_Walker extends Walker_Nav_Menu {
// The code isn't even worth showing because I've tried at least a dozen combinations and nothing's worked
}
?>
</code></pre>
<p>And finally, in my sidebar.php I have this:</p>
<pre><code><?php
if ( has_nav_menu( "side-menu" ) ) {
wp_nav_menu( array(
"theme_location" => "side-menu",
"container_class" => "side-menu",
"walker" => new Clickable_Dropdown_Walker() ) );
}
?>
</code></pre>
<p>Any help would be appreciated, thanks!</p>

] | I'm trying to create a nav menu with a clickable dropdown function but minimize scripting at the same time, so I found out a way to achieve this with an invisible input box and CSS. My only problem is I have no experience with PHP and getting the menu to load the right HTML is very frustrating (it took me forever just to get the custom walker to show up in the first place). This is the effect I want to achieve - the same default WordPress menu, but the menu items with children are slightly different:
```
<ul>
<li>A menu item</li>
<li>A menu item</li>
<li>
<input id="check-(item-id)" type="checkbox" />
<label for="check-(item-id)">A menu item with children</label>
<ul>
<li>Child one</li>
<li>Child two</li>
</li>
<li>A menu item</li>
</ul>
```
In my functions.php file, I have this:
```
<?php
/*---- Custom Menu Settings ----*/
function custom_menus() {
$locations = array(
"top-menu" => __( "Top Menu" ),
"side-menu" => __( "Side Menu" ),
);
register_nav_menus( $locations );
}
add_action( "init", "custom_menus" );
class Clickable_Dropdown_Walker extends Walker_Nav_Menu {
// The code isn't even worth showing because I've tried at least a dozen combinations and nothing's worked
}
?>
```
And finally, in my sidebar.php I have this:
```
<?php
if ( has_nav_menu( "side-menu" ) ) {
wp_nav_menu( array(
"theme_location" => "side-menu",
"container_class" => "side-menu",
"walker" => new Clickable_Dropdown_Walker() ) );
}
?>
```

This my code for making the request which is being made from the wordpress frontend.
```
apiFetch({

});
``` | Based on the authentication documentation [here](https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/) - a nonce key needs to be passed with each request.
So if the nonce key is being cached on the frontend beyond its lifespan, you will need to hook into the API request before the authentication step and replace the cached nonce key with a valid one.
WordPress provides a `rest_send_nocache_headers` filter for us to hook into ([See here](https://developer.wordpress.org/reference/hooks/rest_send_nocache_headers/)). This lets us perform an action before the authentication.
```
$send_no_cache_headers = apply_filters('rest_send_nocache_headers', is_user_logged_in());
if (!$send_no_cache_headers && !is_admin() && $_SERVER['REQUEST_METHOD'] == 'GET') {
$nonce = wp_create_nonce('wp_rest');
$_SERVER['HTTP_X_WP_NONCE'] = $nonce;
}
```
In the above example, we hook into the filter passing the `is_user_logged_in()` function as the parameter. This will return true or false.
Then in our query, if the user is not logged in, they are not in the admin and, this is a `GET` request we proceed with switching the invalid nonce key with a valid one. |

] | I'm working on small, vue based SPA. I'm using axios to get data from api that I'm interested about. The problem is that parameters are not working in any way, the same happens in Postman (I tried Postman because I thought that there is an error in my code, but there is not). Let's say I want to get posts from category 12 and order them ascending. So what I would try is something like this:
```
http://api-address.com/wp-json/wp/v2/posts/?categories=12&order=asc
```
Call presented above returns posts **in wrong order**. I'm struggling with this and can't make it work - so frustrating that official documentation lacks real usage examples... | If results should be ordered by a method other than the default `asc` or `desc`, you should also pass the `orderby` parameter. This gives you the ability to order by title, date, parent, type and many more that can be seen [here](https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters).
For example, a request ordering the results a-z by title would be:
```
http://api-address.com/wp-json/wp/v2/posts/?categories=12&order=asc&orderby=title
``` |
341,516 | <p>I am Creating New Wordpress Plugin and splitting my code into different files for code management.
Here is code of my main Plugin file which <code>my-best-plugin.php</code>with following code:</p>
<pre><code><?php
if ( ! defined('ABSPATH') ){
die;
}
if(!defined('MY_PLUGIN_PATH')) {
define( 'MY_PLUGIN_PATH', plugin_dir_path(__FILE__) );

require_once MY_PLUGIN_PATH .'inc/mbp-plugin-activate.php';
MBPActivate::activate();
}
}
$pluginInstance = new MyBestPlugin();
// activation
register_activation_hook( __FILE__ , array( $pluginInstance, 'mbp_activate' ) );
}
</code></pre>
<p>Now in my second file which is for activation is located in <code>inc/mbp-plugin-activate.php</code> and code is below:</p>
<pre><code><?php
class MBPActivate {
public static function activate(){
// I want to do more here by calling functions
// cpt();
// dont know how to call function cpt()
// also not sure is it running properly or not :P
add_action('init', array( 'MBPActivate','cpt' ));
flush_rewrite_rules();
}
public static function cpt(){
register_post_type('book', ['public'=>true, 'label'=>'Books']);
}
}
</code></pre>
<p>first Im not sure my plugin activate file is running or not but giving No error, also when I call my own functions it gives fatal error OR headers already sent error.
Please tell me how to call my functions during activation from activate plugin file.
Thanks in advance :) </p>

There are two blog posts on the development install I am working with. But neither of them display with the navigational links. | As suggested by the default link labels, "Older Entries" and "Newer Entries", `get_next_posts_link()` and `get_next_posts_link()` are for outputting links between pages of posts. If you only have 2 posts, and your posts per page setting is set to anything higher than 1, then you're not going to have more than one page of any archive or your blog, so the links won't appear.
If you want links between single posts, then the correct functions are [`get_next_post_link()`](https://developer.wordpress.org/reference/functions/get_next_post_link/) and [`get_previous_post_link()`](https://developer.wordpress.org/reference/functions/get_previous_post_link/). Those functions *do* need to be in the loop.
While it's technically possible to use `index.php` for single posts and archives/the blog, you can avoid some confusion by starting with at least `index.php` for your lists of posts, and `singular.php` for single posts and pages. Use `get_next_posts_link()` and `get_next_posts_link()` for links between pages in `index.php`, outside the loop, but use `get_next_post_link()` and `get_previous_post_link()` for links between single posts in `singular.php`, inside the loop. |
341,608 | <p>I have created a custom post type and I got it to show in the REST API.

I am aware of the other WP function to register a meta field (<code>register_meta</code>). However since the documentation reads that it cannot be applied to a custom post type only I chose to use register_rest_field instead.

function slug_update_post_meta_cb( $value, $object, $field_name ) {

And you can actually use [`register_meta()`](https://developer.wordpress.org/reference/functions/register_meta/) with a custom post type:
```php
register_meta( 'post', 'myfield', [
'object_subtype' => 'custom_type', // Limit to a post type.
'type' => 'string',
'description' => 'My Field',
'single' => true,
'show_in_rest' => true,

341,726 | <p>I'm rewording this because, as it's correctly been pointed out, the original post was "woefully inadequate." I made a plugin which has tabbed views for the various settings. It's based on this <a href="https://github.com/hlashbrooke/WordPress-Plugin-Template" rel="nofollow noreferrer">Wordpress Plugin Template</a>. The template uses the WP Settings API to construct the settings page and display the tabs. The form uses the default <code>_wpnonce</code> for the submit/save settings button.</p>

] | I'm rewording this because, as it's correctly been pointed out, the original post was "woefully inadequate." I made a plugin which has tabbed views for the various settings. It's based on this [Wordpress Plugin Template](https://github.com/hlashbrooke/WordPress-Plugin-Template). The template uses the WP Settings API to construct the settings page and display the tabs. The form uses the default `_wpnonce` for the submit/save settings button.
The tabs are link elements that alter the page URL query string, e.g., from `/wp-admin/options-general.php?page=my_plugin_settings&tab=tab_1` to `/wp-admin/options-general.php?page=my_plugin_settings&tab=tab_2`.
The question is now: how to create a nonce for the tabs and check it when the page loads or the user selects one of the tabs.

I thought the API handled nonces automagically? Should I be concerned? Or is the code OK as it is? If not, how should I fix this?
EDIT: In light of the answers, the API provides a default nonce `<input type="hidden" id="_wpnonce" name="_wpnonce" value="$int">` & the associated hidden field `<input type="hidden" name="_wp_http_referer" value="/wp-admin/options-general.php?page=_settings">`. How do I verify? I've tried, unsuccessfully:
```
if ( isset( $_POST['tab'] ) && $_POST['tab'] ) {
if ( ! wp_verify_nonce( '_wpnonce' ) ) {
wp_die( 'Go away!' );
} else {
$current_section = sanitize_text_field( wp_unslash( $_POST['tab'] ) );
}
} else {
if ( isset( $_GET['tab'] ) && $_GET['tab'] ) {
if ( ! wp_verify_nonce( '_wpnonce' ) ) {
wp_die( 'Go away!' );
} else {
$current_section = sanitize_text_field( wp_unslash( $_GET['tab'] ) );
}
}
}
``` | I'm not certain why it would cause an infinite loop, but make sure not to use `$wp_query` as the variable name for your custom query. It's a [reserved global variable](https://codex.wordpress.org/Global_Variables) for the main query. Use a different name for the variable. I'd also suggest using `wp_reset_postdata()` after the loop:
```
$my_query = new WP_Query( $args );
if ( $my_query->have_posts() ) :
while ( $my_query->have_posts() ) {
$my_query->the_post();
}
else:
echo "nothing found.";
endif;
wp_reset_postdata();
``` |
341,742 | <p>I have an activation hook to create 2 new database tables that don't exist, only the second table is created from this code:</p>
<pre><code> public function add_tables() {
// Global $wpdb
global $wpdb;
$wpdb->hide_errors();
// Require upgrade
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
// Set charset
$collate = '';
if ( $wpdb->has_cap( 'collation' ) ) {
$collate = $wpdb->get_charset_collate();
}
// SQL query
$sql = "
CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test1 (
test_id bigint(20) NOT NULL AUTO_INCREMENT,
test_key char(64) NOT NULL,
) $collate;
CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test2 (
test_id bigint(20) NOT NULL AUTO_INCREMENT,
test_key char(64) NOT NULL,
) $collate;
";
// Do SQL
dbDelta( $sql );
}
</code></pre>
<p>Why only the second? If I print out the <code>$sql</code> variable I get the SQL statement and if I run that in phpMyAdmin it creates the 2 tables.</p>
<p>I looked at how plugins like WooCommerce do it (<a href="https://github.com/woocommerce/woocommerce/blob/c04f7b79f972ee854e5f5d726eb78ac04a726b32/includes/class-wc-install.php#L687" rel="nofollow noreferrer">https://github.com/woocommerce/woocommerce/blob/c04f7b79f972ee854e5f5d726eb78ac04a726b32/includes/class-wc-install.php#L687</a>) and it appears I am doing the same as they are.</p>

] | I have an activation hook to create 2 new database tables that don't exist, only the second table is created from this code:
```
public function add_tables() {
// Global $wpdb
global $wpdb;
$wpdb->hide_errors();
// Require upgrade
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
// Set charset
$collate = '';
if ( $wpdb->has_cap( 'collation' ) ) {
$collate = $wpdb->get_charset_collate();
}
// SQL query
$sql = "
CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test1 (
test_id bigint(20) NOT NULL AUTO_INCREMENT,
test_key char(64) NOT NULL,
) $collate;
CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test2 (
test_id bigint(20) NOT NULL AUTO_INCREMENT,
test_key char(64) NOT NULL,
) $collate;
";
// Do SQL
dbDelta( $sql );
}
```
Why only the second? If I print out the `$sql` variable I get the SQL statement and if I run that in phpMyAdmin it creates the 2 tables.
I looked at how plugins like WooCommerce do it (<https://github.com/woocommerce/woocommerce/blob/c04f7b79f972ee854e5f5d726eb78ac04a726b32/includes/class-wc-install.php#L687>) and it appears I am doing the same as they are. | >
> Why only the second?

Because `dbDelta()` supports `CREATE TABLE table_name` format only. I.e. Exactly "CREATE TABLE" followed by (one space and) the table name.
More specifically, `dbDelta()` uses this regular expression pattern: `CREATE TABLE ([^ ]*)` when parsing the queries into an array indexed by the table name; i.e. `array( 'table_1' => 'query', 'table_2' => 'query', ... )`.
Here's the relevant [code](https://core.trac.wordpress.org/browser/tags/5.2/src/wp-admin/includes/upgrade.php#L2547):
```php
$cqueries = array(); // Creation Queries
...
// Create a tablename index for an array ($cqueries) of queries
foreach ( $queries as $qry ) {
if ( preg_match( '|CREATE TABLE ([^ ]*)|', $qry, $matches ) ) {
$cqueries[ trim( $matches[1], '`' ) ] = $qry;
$for_update[ $matches[1] ] = 'Created table ' . $matches[1];
}
...
}
```
So in the case of `CREATE TABLE IF NOT EXISTS table_name`, the table name is (seen as) `IF` and not `table_name` due to the regular expression pattern:
```php
preg_match( '|CREATE TABLE ([^ ]*)|', 'CREATE TABLE IF NOT EXISTS table_name', $matches );
var_dump( $matches );
/* Output:
array(2) {
[0]=>
string(15) "CREATE TABLE IF"
[1]=>
string(2) "IF"
}
*/
preg_match( '|CREATE TABLE ([^ ]*)|', 'CREATE TABLE table_name', $matches );
var_dump( $matches );
/* Output:
array(2) {
[0]=>
string(23) "CREATE TABLE table_name"
[1]=>
string(10) "table_name"
}
*/
```
And in your case, both queries do match that pattern, but since the table names are both (seen as) `IF`, the first/previous array item (`$queries['IF']`) is then overridden. Hence only the second table (the one in the final value of `$queries['IF']`) gets created.
And WooCommerce actually do **not** have `CREATE TABLE IF NOT EXISTS` in their code:
<https://github.com/woocommerce/woocommerce/blob/c04f7b79f972ee854e5f5d726eb78ac04a726b32/includes/class-wc-install.php#L687>
**Possible Solution when using the `CREATE TABLE IF NOT EXISTS table_name` format**
Call `dbDelta()` for each of the queries, as in @FahamShaikh's answer:
```php
$queries = [ // array of queries
"CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test1 ...",
"CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test2 ...",
];
foreach ( $queries as $sql ) {
dbDelta( $sql );
}
```
Or:
```php
dbDelta( "CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test1 ..." );
dbDelta( "CREATE TABLE IF NOT EXISTS " . $wpdb->prefix . "test2 ..." );

It's not documented on their website, but a [comment from the developer](https://codecanyon.net/item/booked-appointments-appointment-booking-for-wordpress/9466968/comments?page=50&filter=all#comment_12081430) states:

Which implies that callback functions for the `booked_new_appointment_created` hook receive the appointment ID as an argument:
```
function add_to_system( $appointment_id ) {
mail( '[email protected]', 'My subject', $appointment_id );
}
add_action( 'booked_new_appointment_created', 'add_to_system', 99, 1 );
```
Doing it this way is far more reliable, as you can be certain that the ID of the appointment you're using is the ID of the appointment that triggered the action, and not some other post or page that might be the 'current' post in the global state.
This is a good rule of thumb for all hooks: Use the arguments passed to callbacks wherever possible instead of global variables. |

] | Is it possible to call a function from functions.php in custom page or blog post?
I put simple function in functions.php:
```
function testTest()
{
echo "Test";
}
```
And called it from the page:
```
<?php testTest();?>
```
But it doesn't work. Do I need to make a plugin to use simple function like that inside one chosen custom page?
Thanks for your answer,
Mary | You could use [add\_shortcode](https://codex.wordpress.org/Function_Reference/add_shortcode) if you want to use it within the editor.
```
function footag_func() {
return "Test";
}
add_shortcode( 'footag', 'footag_func' );
```
And then use [footag] in your editor.
Or
Use code like this in functions.php and add a conditional tag
```
add_action( 'loop_start', 'your_function' );
function your_function() {
if ( is_singular('post') ) {
echo 'Test';
}
}
```
or
Create a function in functions.php
```
function your_function() {
return 'Test';
}
```
And then use this in your template
```
echo your_function();

] | I have been working on a project where I will have to call a method(that accepts user id as an input) from a click of a submit button(Accept button).
I have been trying all the ways but the real challenge I am facing is how to get the user id in the front end and pass it to the method.
My method updates the user meta of that particular user.
**Html code:**
```
<div id="modal">
<div class="modalconent">
<h3 align=center>GDPR</h3>
<p>This is a GDPR Pop Up</p><br><br><br>
<form>
<input name="accept" type="checkbox" value="Gdpr" required/>I accept the GDPR
<input type="submit" id="accept-button" value="Accept">
</form>
</div>
</div>
<script>
window.onload = function () {
document.getElementById('accept-button').onclick = function () {
document.getElementById('modal').style.display = "none"
};
};
</script>
```
At present, my Accept button when clicked is only displaying none. I want to call the method along with display:none;
**My PHP code:**
```
function updateHasReadFlag($user) {
// I added support for using this function either with user ID or user object
if ( $user && is_int( $user ) ) {
$user_id = $user;
} else if ( ! empty( $user->ID ) ) {
$user_id = $user->ID;
} else {
return;
}
return update_user_meta( $user_id, 'META_KEY', true );
}
```
**The form code generated :**
```
<form method="post" action="<?php echo esc_url( home_url() ); ?>">
<input name="accept" type="checkbox" value="Gdpr" required=""> I accept the GDPR
<input type="submit" id="accept-button" value="Accept">
<!--?php wp_nonce_field( 'accept-gdpr', 'accept_gdpr_nonce' ); ?-->
</form>
```
I do not understand why nonce field is commented. This is exactly what the code got generated, I have not edited anything in the code. | You could use AJAX if you don't want to reload the current page — i.e. upon clicking the "Accept" button, make an AJAX request to update the user metadata, all without leaving the current page.
However, the solution I'm proposing is *not* using AJAX; instead, we simply submit the form (set its `action` attribute value) to the homepage and then we use the `template_redirect` hook to update the metadata (and redirect back to the previous or referring page).
The Steps
---------
1. Change the `form` tag to:
```
<form method="post" action="<?php echo esc_url( home_url() ); ?>">
```
and add this [nonce](https://codex.wordpress.org/WordPress_Nonces) field:
```
<?php wp_nonce_field( 'accept-gdpr', 'accept_gdpr_nonce' ); ?>
```
so your `form` now looks like:
```
<form method="post" action="<?php echo esc_url( home_url() ); ?>">
<input name="accept" type="checkbox" value="Gdpr" required /> I accept the GDPR
<input type="submit" id="accept-button" value="Accept" />
<?php wp_nonce_field( 'accept-gdpr', 'accept_gdpr_nonce' ); ?>
</form>
```
2. Add this to the theme `functions.php` file:
```
function accept_gdpr() {
// Check if the user is authenticated.
if ( ! is_user_logged_in() ) {
return;
}
// Check if we have all necessary data.
if ( empty( $_POST['accept_gdpr_nonce'] ) || empty( $_POST['accept'] ) ||
'Gdpr' !== $_POST['accept'] ) {
return;
}
// Verify the nonce.
if ( ! wp_verify_nonce( $_POST['accept_gdpr_nonce'], 'accept-gdpr' ) ) {
return;
}
// Update the meta.
update_user_meta( get_current_user_id(), 'META_KEY', '1' );
// Redirect back to the previous page.
wp_safe_redirect( wp_get_referer() );
exit;
}
add_action( 'template_redirect', 'accept_gdpr' );
```
**Notes:**
1. The `Gdpr` as in `'Gdpr' !== $_POST['accept']` is the same as in the `<input name="accept" type="checkbox" value="Gdpr" required />` above.
2. *Be sure to replace the `META_KEY` with the actual meta key.*
3. I believe that the GDPR acceptance is aimed at logged-in users only, so that's why I used `is_user_logged_in()` and `get_current_user_id()` in the above code/function.

UPDATE

`wp_safe_redirect()` didn't work for the OP, so he used `wp_redirect()`. |
342,309 | <p>I have a custom post type of Hotel. Hotels can be can be categorised with the taxonomy Resort. </p>
<p>On my search page I need to be able to list hotels <strong>and</strong> taxonomy terms in the results, as separate results. eg:</p>
<pre><code>Resort Name
Hotel Name
Hotel Name
Hotel Name
</code></pre>
<p>Resorts should come first, followed by hotels and anything else. As far as I know taxonomy terms are not shown by default in WordPress search. </p>
<p>In my functions.php I'm currently limiting the search to specific post types:</p>
<pre><code>function filter_search($query) {
// Don't run in admin area
if(!is_admin()) {
// Limit search to posts
if($query->is_main_query() && $query->is_search()) {
$query->set('post_type', array('hotel', 'post', 'activities', 'page'));
}
// Return query
return $query;
}
}
add_filter('pre_get_posts', 'filter_search');
</code></pre>
<p>Then in my search.php I am grouping the results by post type: </p>
<pre><code><?php $types = array('hotel', 'post', 'activities', 'page');
foreach( $types as $type ){
echo '<div class="results"> '; ?>
<?php while( have_posts() ){
the_post();
if( $type == get_post_type() ){ ?>
<div class="result">
<div class="result-inner">
<h2>
<?php if ( $type == "hotel" ) { ?>
Hotel:
<?php } elseif ( $type == "activities" ) { ?>
Activity:
<?php } elseif ( $type == "post" ) { ?>
Blog Post:
<?php } elseif ( $type == "page" ) { ?>
Page:
<?php } else { ?>
Page:
<?php } ?>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
</h2>
<p class="blog-more"><a href="<?php the_permalink() ?>" class="button">View Page</a></p>
</div>
</div>
<?php }
}
rewind_posts();
echo '</div> ';
} ?>
</code></pre>
<p>What I'm struggling with is how to tell WordPress to show the taxonomy term (Resort) in the results as it's own result. Can anybody help?</p>
<p>UPDATE: I'm happy to preserve the default WordPress search order. The results don't have to be <em>grouped</em> by taxonomy term. I just need to be able to spit out the term <em>as a result itself</em>, with a link to the term (and be counted in the search count query). So if a search matches a taxonomy term that should come first, followed by the other results in whatever order. </p>

] | I have a custom post type of Hotel. Hotels can be can be categorised with the taxonomy Resort.
On my search page I need to be able to list hotels **and** taxonomy terms in the results, as separate results. eg:
```
Resort Name
Hotel Name
Hotel Name
Hotel Name
```
Resorts should come first, followed by hotels and anything else. As far as I know taxonomy terms are not shown by default in WordPress search.
In my functions.php I'm currently limiting the search to specific post types:
```
function filter_search($query) {
// Don't run in admin area
if(!is_admin()) {
// Limit search to posts
if($query->is_main_query() && $query->is_search()) {
$query->set('post_type', array('hotel', 'post', 'activities', 'page'));
}
// Return query
return $query;
}
}
add_filter('pre_get_posts', 'filter_search');
```
Then in my search.php I am grouping the results by post type:
```
<?php $types = array('hotel', 'post', 'activities', 'page');
foreach( $types as $type ){
echo '<div class="results"> '; ?>
<?php while( have_posts() ){
the_post();
if( $type == get_post_type() ){ ?>
<div class="result">
<div class="result-inner">
<h2>
<?php if ( $type == "hotel" ) { ?>
Hotel:
<?php } elseif ( $type == "activities" ) { ?>
Activity:
<?php } elseif ( $type == "post" ) { ?>
Blog Post:
<?php } elseif ( $type == "page" ) { ?>
Page:
<?php } else { ?>
Page:
<?php } ?>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
</h2>
<p class="blog-more"><a href="<?php the_permalink() ?>" class="button">View Page</a></p>
</div>
</div>
<?php }
}
rewind_posts();
echo '</div> ';
} ?>
```
What I'm struggling with is how to tell WordPress to show the taxonomy term (Resort) in the results as it's own result. Can anybody help?
UPDATE: I'm happy to preserve the default WordPress search order. The results don't have to be *grouped* by taxonomy term. I just need to be able to spit out the term *as a result itself*, with a link to the term (and be counted in the search count query). So if a search matches a taxonomy term that should come first, followed by the other results in whatever order. | >

`WP_Query::$posts` are `WP_Post` objects and can't include (or be mixed with) term/`WP_Term` objects.
However, there's a way to achieve what you want — use `get_terms()` to search for the taxonomy terms and modify the `WP_Query`'s `posts_per_page` and `offset` parameters to make the matched terms *as if* they're part of the actual search results (which are posts).
Note though, for now, `get_terms()`/`WP_Term_Query` supports single search keywords only — i.e. `foo, bar` is treated as one keyword — in `WP_Query`, that would be two keywords (`foo` and `bar`).
The Code/Steps
--------------
### In `functions.php`:
Add this:
```php
function wpse342309_search_terms( $query, $taxonomy ) {
$per_page = absint( $query->get( 'posts_per_page' ) );
if ( ! $per_page ) {
$per_page = max( 10, get_option( 'posts_per_page' ) );
}
$paged = max( 1, $query->get( 'paged' ) );
$offset = absint( ( $paged - 1 ) * $per_page );
$args = [
'taxonomy' => $taxonomy,
// 'hide_empty' => '0',
'search' => $query->get( 's' ),
'number' => $per_page,
'offset' => $offset,
];
$query->terms = [];
$terms = get_terms( $args );
if ( ! is_wp_error( $terms ) && ! empty( $terms ) ) {
$query->terms = $terms;
}
$args['offset'] = 0; // always 0
$args['fields'] = 'count';
$query->found_terms = get_terms( $args );
$query->term_count = count( $query->terms );
$query->terms_per_page = $per_page; // for WP_Query::$max_num_pages
$query->is_all_terms = ( (int) $per_page === $query->term_count );
$query->set( 'posts_per_page', max( 1, $per_page - $query->term_count ) );
$query->set( 'offset', $query->term_count ? 0 :
max( 0, $offset - $query->found_terms ) );
}
```
In the `filter_search()`, add `wpse342309_search_terms( $query, 'resort' );` after this line:
```php
$query->set( 'post_type', array( 'hotel', 'post', 'activities', 'page' ) );
```
### In `search.php`, for the main WordPress query:
```php
<?php if ( have_posts() ) :
$total = $wp_query->found_posts + $wp_query->found_terms;
$wp_query->max_num_pages = ceil( $total / $wp_query->terms_per_page );
echo '<div class="results">';
// Display terms matching the search query.
if ( ! empty( $wp_query->terms ) ) {
global $term; // for use in the template part (below)
foreach ( $wp_query->terms as $term ) {
get_template_part( 'template-parts/content', 'search-term' );
}
}
// Display posts matching the search query.
if ( ! $wp_query->is_all_terms ) {
while ( have_posts() ) {
the_post();
get_template_part( 'template-parts/content', 'search-post' );
}
}
echo '</div><!-- .results -->';
// Display pagination.
//the_posts_pagination();
echo paginate_links( [
'total' => $wp_query->max_num_pages,
'current' => max( 1, get_query_var( 'paged' ) ),
] );
else :
echo '<h1>No Posts Found</h1>';
endif; // end have_posts()
?>
```
### In `search.php`, for a *custom* WordPress query:
You should always *manually* call `wpse342309_search_terms()`.
```php
<?php
$my_query = new WP_Query( [
's' => 'foo',
// ... your args here ...
] );
// Manually apply the terms search.
wpse342309_search_terms( $my_query, 'resort' );
if ( $my_query->have_posts() ) :
$total = $my_query->found_posts + $my_query->found_terms;
$my_query->max_num_pages = ceil( $total / $my_query->terms_per_page );
echo '<div class="results">';
// Display terms matching the search query.
if ( ! empty( $my_query->terms ) ) {
global $term; // for use in the template part (below)
foreach ( $my_query->terms as $term ) {
get_template_part( 'template-parts/content', 'search-term' );
}
}
// Display posts matching the search query.
if ( ! $my_query->is_all_terms ) {
while ( $my_query->have_posts() ) {
$my_query->the_post();
get_template_part( 'template-parts/content', 'search-post' );
}
}
echo '</div><!-- .results -->';
// Display pagination.
echo paginate_links( [
'total' => $my_query->max_num_pages,
'current' => max( 1, get_query_var( 'paged' ) ),
] );
else :
echo '<h1>No Posts Found</h1>';
endif; // end have_posts()
?>
```
### Template Part 1: `template-parts/content-search-term.php`
```php
<?php global $term;
$term_link = get_term_link( $term, 'resort' ); ?>
<div class="result">
<div class="result-inner">
<h2><a href="<?php echo esc_url( $term_link ); ?>"><?php echo esc_html( $term->name ); ?></a></h2>
<p class="blog-more"><a href="<?php echo esc_url( $term_link ); ?>" class="button">View Page</a></p>
</div>
</div>
```
### Template Part 2: `template-parts/content-search-post.php`
```php
<?php $type = get_post_type(); ?>
<div class="result">
<div class="result-inner">
<h2>
<?php if ( $type == "hotel" ) { ?>

I'm reluctant to update the entire theme purely because of this glitch if I can fix it. | In a case like this, you're probably going to need to check the conditions in `dynamic_sidebar` to find out what is not happening.

```
Which you put in your theme `functions.php` and then can check via `http://example.com/?debugsidebar=my_sidebar`
There is a small difference in the bugout checks is `is_active_sidebar` and `dynamic_sidebar`
From `is_active_sidebar` function:
```
! empty( $sidebars_widgets[ $index ] );
```
From `dynamic_sidebar` function:
```
if ( empty( $wp_registered_sidebars[ $index ] ) || empty( $sidebars_widgets[ $index ] ) || ! is_array( $sidebars_widgets[ $index ] ) ) {
```
Since the middle condition is the same, this means that either the sidebar is not being registered correctly (unlikely as that seems fine) - but more likely, the data for that key is not an array of widgets. You will find out from running the debug function.
It may possibly show you a mismatch or corrupt data in the `sidebars_widgets` option value (If needs be you can that check against a value from you `wp_options` table backup from when it was working.) |

342,433 | <p>I'm struggling to get tabbed plugin settings, created with WordPress Settings API to work.</p>
<p>The first tab saves settings correctly. However, every time when I click on "Save Changes" button for any other tab, a white screen with the following error appears:</p>
<blockquote>
<p>ERROR: Options page not found</p>
</blockquote>
<p>Chrome and Apache log show POST 500 error. I see that form data to submit appears to be correct and according to what is submitted for the first tab that works <code>general_section</code> :</p>
<pre><code>option_page: account_section
action: update
_wpnonce: 2d40b0a357
_wp_http_referer: /staging/wp-admin/options-general.php?page=woo-extra-settings&tab=account
eswc_settingz[eswc_redirect]: 1
submit: Save Changes
</code></pre>
<p>The fields are registered only when the proper tab is selected to avoid resetting values in other tabs to defaults on save.</p>
<p>The code from this topic is included in my example, but it didn't fix the problem:</p>
<p><a href="https://wordpress.stackexchange.com/questions/139660/error-options-page-not-found-on-settings-page-submission-for-an-oop-plugin">"Error: Options Page Not Found" on Settings Page Submission for an OOP Plugin</a></p>
<p>I used PHP console extension for Chrome and a plugin to print values to Chrome console for troubleshooting, for example:</p>
<pre><code>PC::debug( 'general', 'tab name' );
</code></pre>
<p>This is now commented. The code can be used as a minimal part of my plugin to generate a 2-tab settings page in the default "Settings" menu and reproduce the issue that I'm having.</p>
<p>On tab activation, the console returns the following values (<code>whitelist_custom_options_page</code> function doesn't execute):</p>
<p>"General" (1st tab):</p>
<pre><code>tab name: general
add settings section - page: woo-extra-settings
add settings section - id: general_section
</code></pre>
<p>"Account" (2nd tab)</p>
<pre><code>tab name: account
add settings section - page: woo-extra-settings
add settings section - id: account_section
</code></pre>
<p>On settings save, the values are:</p>
<p>"General" (1st tab):</p>
<pre><code>tab name: general
add settings section - page: woo-extra-settings
add settings section - id: general_section
whitelist page: woo-extra-settings
whitelist section: general_section
whitelist option: eswc_settingz
</code></pre>
<p>For "Account" (2nd tab) the values are all the same, which means that on saving the settings, my code incorrectly perceives any tab as 1st tab, what is the reason for the problem that I have.</p>
<p>How can I fix this issue in a way that is close to my current implementation?</p>

I used PHP console extension for Chrome and a plugin to print values to Chrome console for troubleshooting, for example:
```
PC::debug( 'general', 'tab name' );
```
This is now commented. The code can be used as a minimal part of my plugin to generate a 2-tab settings page in the default "Settings" menu and reproduce the issue that I'm having.
On tab activation, the console returns the following values (`whitelist_custom_options_page` function doesn't execute):
"General" (1st tab):
```
tab name: general
add settings section - page: woo-extra-settings
add settings section - id: general_section
```
"Account" (2nd tab)
```
tab name: account
add settings section - page: woo-extra-settings
add settings section - id: account_section
```
On settings save, the values are:
"General" (1st tab):
```
tab name: general
add settings section - page: woo-extra-settings
add settings section - id: general_section
whitelist page: woo-extra-settings
whitelist section: general_section
whitelist option: eswc_settingz
```
For "Account" (2nd tab) the values are all the same, which means that on saving the settings, my code incorrectly perceives any tab as 1st tab, what is the reason for the problem that I have.
How can I fix this issue in a way that is close to my current implementation?
Here is the code:
```
class extra_settings_settings {
private $options;
private $settings_page_name;
private $settings_menu_name;
public function __construct() {
if ( is_admin() ) {
$this->settings_page_name = 'woo-extra-settings';
$this->settings_menu_name = 'Woo Extra Settings';
// Tracks new sections for whitelist_custom_options_page()

``` | First Thing

And because of that, you should pass the proper tab name/slug to the `wp-admin/options.php` page which is where the form is being submitted to.
1. You can simply pass it as a query string in the form `action` attribute value:
```
<form method="post" action="<?php echo esc_url( add_query_arg( // wrapped for clarity
'tab', $active_tab, admin_url( 'options.php' )
) ); ?>">
```
2. *Or* in `create_settings_page()`, add a hidden input field having the tab slug as the value:
```
echo '<input type="hidden" name="tab" value="' . esc_attr( $active_tab ) . '" />';
submit_button();
```
And then in the `display_options()`, retrieve the tab slug using `$_REQUEST`:
```
$active_tab = isset( $_REQUEST['tab'] ) ? $_REQUEST['tab'] : 'general';
```
Either way, the point is so that the `register_setting()` calls in the `display_options()` are invoked. Because otherwise, WordPress would throw the "options page not found" error because the option page is *not registered*.
You could use the `whitelist_options` filter, but I'd rather want the `register_setting()` calls be invoked, so I removed this and the associated callback (`whitelist_custom_options_page()`):
```
add_action( 'whitelist_options', array( $this, 'whitelist_custom_options_page' ),11 );
```
Second Thing
------------
Since you're using the same database *option name* (`eswc_settingz`) for all tabs/fields, you should then merge the saved data with the one being submitted:
```
public function sanitize_general( $input ) {
$new_input = (array) get_option( 'eswc_settingz' ); // get saved data
... add/update new data
return $new_input;
}
public function sanitize_account( $input ) {
$new_input = (array) get_option( 'eswc_settingz' ); // get saved data
... add/update new data
return $new_input;
}
```
Or you could use *different* database option names:
```
register_setting( 'general_section', 'eswc_general_settingz', array( $this, 'sanitize_general' ) );
register_setting( 'account_section', 'eswc_account_settingz', array( $this, 'sanitize_account' ) );
```
Btw, is that "z" in the `settingz` a typo? Maybe it was meant to be `settings`?... |

The max number of the posts to be displayed is set to 2 and every page is showing two posts.
If you spot any potential problem with the code, please let me know.
Thank you for reading. | To get the canonical (not `?page=1`) reference URL to start the pagination from you have to change
```
'base' => '%_%'
```
to
```
'base' => get_pagenum_link() . '%_%' // get_pagenum_link() default is '1'
```
which will give you the first page of paginated posts and `%_%` will be replaced by `'format'` parameter on the next pages. |

342,678 | <p>Any help with this would be greatly appreciated - I've been grappling with it for days :)</p>
<p>I have 2 post types - <code>product</code> + <code>offer</code></p>
<p>I have an ACF relationship field <code>related_products</code>. </p>
<p>This field returns an array of post IDs <code>Array ( [0] => 395 [1] => 120 [2] => 388 [3] => 391 )</code></p>
<p>I am using <code>related_products</code> on the <code>offer</code> post type - it's a one-way relationship (not bi-directional). </p>
<p>Each of my post types has a "card" template part that I use in all my loops - that's what I want to do here ... use the <code>related_products</code> IDs to get the <code>product</code> card parts and show them on the <code>offer</code>. </p>
<p>I had no luck with the ACF documentation - but that's probably because I'm a noob. </p>
<ul>
<li><a href="https://www.advancedcustomfields.com/resources/querying-relationship-fields/" rel="nofollow noreferrer">https://www.advancedcustomfields.com/resources/querying-relationship-fields/</a></li>
<li><a href="https://www.advancedcustomfields.com/resources/acf-fields-relationship-query/" rel="nofollow noreferrer">https://www.advancedcustomfields.com/resources/acf-fields-relationship-query/</a></li>
</ul>
<p>Instead, I set up a custom <code>WP_Query</code> that get's me close, but not there. </p>
<p>The <code>if ( $custom_query->have_posts() )</code> IS working - when an <code>offer</code> has related products, the correct product cards ARE displayed. </p>
<p>But, when an <code>offer</code> has no <code>related_products</code>, ALL products are being shown. </p>
<p>My questions are:</p>
<ul>
<li>Is a custom <code>WP_QUERY</code> the right/best way to go about this?</li>
<li>If so, what do I need to fix in the query? </li>
</ul>
<p>Thank you for your time and help :)</p>

] | Any help with this would be greatly appreciated - I've been grappling with it for days :)
I have 2 post types - `product` + `offer`
I have an ACF relationship field `related_products`.
This field returns an array of post IDs `Array ( [0] => 395 [1] => 120 [2] => 388 [3] => 391 )`
I am using `related_products` on the `offer` post type - it's a one-way relationship (not bi-directional).
Each of my post types has a "card" template part that I use in all my loops - that's what I want to do here ... use the `related_products` IDs to get the `product` card parts and show them on the `offer`.
I had no luck with the ACF documentation - but that's probably because I'm a noob.
* <https://www.advancedcustomfields.com/resources/querying-relationship-fields/>
* <https://www.advancedcustomfields.com/resources/acf-fields-relationship-query/>
Instead, I set up a custom `WP_Query` that get's me close, but not there.
The `if ( $custom_query->have_posts() )` IS working - when an `offer` has related products, the correct product cards ARE displayed.
But, when an `offer` has no `related_products`, ALL products are being shown.
My questions are:
* Is a custom `WP_QUERY` the right/best way to go about this?
* If so, what do I need to fix in the query?
Thank you for your time and help :)
```

// do something else

wp_reset_query();
``` | My OP is about using the ACF relationship field in `WP_QUERY`. The ACF documentation leaves out one helpful bit that @JacobPeattie supplied.
My final working code looks like this:
```
// ACF field is set to return IDs.

However, part of Jacob's explanation and subsequent comments are wrong. Because I rely on this community for accurate information, I can't accept his answer as correct.
Jacob incorrectly asserts that passing an array of IDs to `WP_QUERY` and then using the `fields` parameter to return only IDs is redundant and won't work.
You can use any number of things to inform `WP_QUERY` which posts to GET - terms, post type, IDs. This is completely separate from what you tell the query to RETURN - there is nothing redundant about passing then returning IDs.
The `fields` parameter defaults to returning all fields. Alternatively, you can set `fields` to return `ids` (note plural).
Deciding to return all fields or just IDs is a matter of optimization - if you don't need all fields, then don't return them.
Here are two examples from my live site demonstrating that YOU DO NOT NEED ALL FIELDS in many common scenarios. You can easily try these for yourself and I've linked to more info below.
This example displays a field - `the_title` ... super common, I use it all the time and you don't need to return all fields to do it.
```
$args = array(
'post_type' => 'product',
'fields' => 'ids',
);
$custom_query = new WP_Query( $args );
if ( $custom_query->have_posts() ) :
while ( $custom_query->have_posts() ) :
$custom_query->the_post();
the_title();
endwhile;
else :
// do something else
endif;
wp_reset_query();
```
Here's an even more complex / optimized example. This one is for displaying a template part. This part has standard stuff like `the_title` + ACF fields + an Add Favorite feature + pulls in other parts. The results are filterable by FacetWP.
Again, you only need `WP_QUERY` to return IDs.
```
$args = array(
'post_type' => 'product',
'fields' => 'ids',
'cache_results' => false,
'update_post_meta_cache' => false,
'update_post_term_cache' => false,
'facetwp' => true,
);
$custom_query = new WP_Query( $args );
if ( $custom_query->have_posts() ) :
while ( $custom_query->have_posts() ) :
$custom_query->the_post();
get_template_part( 'parts/card', get_post_type() );
endwhile;

global $post;
foreach ( $related_posts as $post ) {
setup_postdata( $post );

wp_reset_postdata();
```
Note the following points about the code:
1. I use [`wp_list_pluck()`](https://developer.wordpress.org/reference/functions/wp_list_pluck/) to get the category IDs in a single line.
2. I don't use `post__not_in`. This has known [performance issues](https://wpvip.com/documentation/performance-improvements-by-removing-usage-of-post__not_in/). Instead I query for 1 more post than we need so that we can remove the current post later if it appears in the results. This will be faster than using `post__not_in`.
3. I use `get_posts()` instead of `WP_Query`. This is because it has more appropriate defaults for secondary queries (such as setting `ignore_sticky_posts` and `no_found_rows` to `true`.
4. Once we have results I use `wp_list_filter()` to remove the current post, if it appears in the results. I do this by using `get_queried_oject_id()` to get the ID of the current post. If it doesn't appear in the results then I use `array_pop()` to remove the last post to get back down to 3 posts. |

Shane Madsen | Post types in WordPress have a list of capabilities that govern permissions surrounding them. These are:
```
edit_post
read_post
delete_post
edit_posts
edit_others_posts
publish_posts
read_private_posts
read
delete_posts
delete_private_posts
delete_published_posts
delete_others_posts
edit_private_posts
edit_published_posts
create_posts
```
Internally each post type matches these to the *actual* capabilities that can be given in WordPress. Most of the time these have the exact same name. So the `edit_posts` capability of the `post` post type is `edit_posts`, while the `edit_posts` capability for the `page` post type is `edit_pages`.
The one exception to this is `create_posts`. This is the post type capability that WordPress checks to decide whether a user can create a new post of that type. It checks this:
```
if ( current_user_can( get_post_type_object( 'page' )->cap->create_posts ) ) {}
```
Unlike the other capabilities, for posts and pages `create_posts` is actually mapped to `edit_posts` and `edit_pages` respectively, not `create_posts` or `create_pages`, which don't exist.
So if you printed `get_post_type_object( 'page' )->cap->create_posts` you'd see that the value is `edit_pages`, and users with that capability can see the Add New button. Because this is `edit_pages` and not `publish_pages`, it allows users to create new pages and posts even if they can't publish them, they'll just be put into pending review, which is the behaviour you want to prevent.
For custom post types you can control this behaviour by setting `create_posts` in the `capabilities` argument to something else:
```
register_post_type(
'my_custom_type',
[
'capabilities' => [
'create_posts' => 'manage_options',
],
]
);
```
For that custom post types, only users with `manage_options` will be able to add new posts.
For the built in post types you can use the `register_post_type_args` filter to set this capability however you'd like for the default post types:
```
function wpse_342743_create_page_capability( $args, $post_type ) {
if ( 'page' === $post_type ) {
$args['capabilities'] = [
'create_posts' => 'manage_options',
];
}
return $args;
}
add_filter( 'register_post_type_args', 'wpse_342743_create_page_capability', 10, 2 );
```
With that code only users with `manage_options` will be able to create new pages, but they will still be able to update them without review if they otherwise have `edit_pages` and `publish_pages`. You can change this capability to be `delete_pages` so that only users who can delete pages can create them, or you could pass your own custom capability that you'll give to users to give them the ability to create pages. |

``` | Post types in WordPress have a list of capabilities that govern permissions surrounding them. These are:
```
edit_post
read_post
delete_post
edit_posts
edit_others_posts
publish_posts
read_private_posts
read
delete_posts
delete_private_posts
delete_published_posts
delete_others_posts
edit_private_posts
edit_published_posts
create_posts
```
Internally each post type matches these to the *actual* capabilities that can be given in WordPress. Most of the time these have the exact same name. So the `edit_posts` capability of the `post` post type is `edit_posts`, while the `edit_posts` capability for the `page` post type is `edit_pages`.
The one exception to this is `create_posts`. This is the post type capability that WordPress checks to decide whether a user can create a new post of that type. It checks this:
```
if ( current_user_can( get_post_type_object( 'page' )->cap->create_posts ) ) {}
```
Unlike the other capabilities, for posts and pages `create_posts` is actually mapped to `edit_posts` and `edit_pages` respectively, not `create_posts` or `create_pages`, which don't exist.
So if you printed `get_post_type_object( 'page' )->cap->create_posts` you'd see that the value is `edit_pages`, and users with that capability can see the Add New button. Because this is `edit_pages` and not `publish_pages`, it allows users to create new pages and posts even if they can't publish them, they'll just be put into pending review, which is the behaviour you want to prevent.
For custom post types you can control this behaviour by setting `create_posts` in the `capabilities` argument to something else:
```
register_post_type(
'my_custom_type',
[
'capabilities' => [
'create_posts' => 'manage_options',
],
]
);
```
For that custom post types, only users with `manage_options` will be able to add new posts.
For the built in post types you can use the `register_post_type_args` filter to set this capability however you'd like for the default post types:
```
function wpse_342743_create_page_capability( $args, $post_type ) {
if ( 'page' === $post_type ) {
$args['capabilities'] = [
'create_posts' => 'manage_options',
];
}
return $args;
}
add_filter( 'register_post_type_args', 'wpse_342743_create_page_capability', 10, 2 );
```
With that code only users with `manage_options` will be able to create new pages, but they will still be able to update them without review if they otherwise have `edit_pages` and `publish_pages`. You can change this capability to be `delete_pages` so that only users who can delete pages can create them, or you could pass your own custom capability that you'll give to users to give them the ability to create pages. |

343,037 | <p>I am writing a migration script which has to read the post_content of posts and then dynamically change some attributes of some custom Gutenberg blocks.</p>
<p>I was able to read the post_content and then convert them into block objects by using the <code>parse_blocks</code> function. I was also able to dynamically change the attributes of the custom blocks by manipulating the block objects.</p>
<p>But I am not able to convert these block objects into the special HTML comments that Gutenberg uses to serialize them so that I can update the post_content.</p>
<p>I found that the PHP part of WordPress core only has <code>parse_blocks</code> function to parse the special HTML comments into block objects and <code>render_block</code> function to render the blocks, but there is no <code>serialize_block</code> function.</p>

] | I am writing a migration script which has to read the post\_content of posts and then dynamically change some attributes of some custom Gutenberg blocks.
I was able to read the post\_content and then convert them into block objects by using the `parse_blocks` function. I was also able to dynamically change the attributes of the custom blocks by manipulating the block objects.
But I am not able to convert these block objects into the special HTML comments that Gutenberg uses to serialize them so that I can update the post\_content.
I found that the PHP part of WordPress core only has `parse_blocks` function to parse the special HTML comments into block objects and `render_block` function to render the blocks, but there is no `serialize_block` function.
I found that in JavaScript there is a function called [`serializeBlock`](https://github.com/WordPress/gutenberg/blob/master/packages/blocks/src/api/serializer.js#L269) which does this. But is there an equivalent of it in PHP which I can call from my migration scripts? | This markup is generated on the js side of things and saved in the content of the block editor, which is why there doesn't seem to be a native PHP function for this.

You could add it as a method in your own class or convert to a standard function like so:
```
/**
* Serializes a block.
*
* @param array $block Block object.
* @return string String representing the block.
*/
function serialize_block( $block ) {
if ( ! isset( $block['blockName'] ) ) {
return false;
}
$name = $block['blockName'];
if ( 0 === strpos( $name, 'core/' ) ) {
$name = substr( $name, strlen( 'core/' ) );
}
if ( empty( $block['attrs'] ) ) {
$opening_tag_suffix = '';
} else {
$opening_tag_suffix = ' ' . json_encode( $block['attrs'] );
}
if ( empty( $block['innerHTML'] ) ) {
return sprintf(
'<!-- wp:%s%s /-->',
$name,
$opening_tag_suffix
);

return sprintf(
'<!-- wp:%1$s%2$s -->%3$s<!-- /wp:%1$s -->',

I suppose that you are using a container of `WP_USER_QUERY::__construct` in the form or `WP_USER_QUERY` or `get_users` or something to that effect.
You can use `'meta_key' => '<YOUR_DESIGNATION_META_KEY>','orderby' => 'meta_value_num,` to get results sorted by your meta key's value.
If you have used a texted based value in for this meta\_key, please consider using a numeric value based system. eg.
* 0 = 'Director'
* 1 = 'CTO'
and so on as this will allow you to achieve what you want with ease and you can event have the designation array globally defined, store the index as user meta based on selected designation and show the designation based on the stored meta value.
Good luck!!

```
$args = array(
'meta_key' => 'member_role',
'orderby' => 'meta_value_num',
'order' => 'ASC'
);
$results = get_users( $args );
```
and then you can iterate with your `foreach` loop.
And do not that the option values for the select drop down must be like 0,1,2,3 etc. |

] | I have the following really simple code:
```
function load_peoplesoft_results() {
global $wpdb;
echo "<h2>Results</h2>";
}
add_shortcode('load_peoplesoft_result_page', 'load_peoplesoft_results()');
```
And I put the following on the page I want to display the page:
```
[load_peoplesoft_result_page]
```
But when I load the page, it just displays the above. I checked the error log, and got the following:
```
[22-Jul-2019 10:26:49] PHP Notice: do_shortcode_tag was called <strong>incorrectly</strong>.
Attempting to parse a shortcode without a valid callback:
load_peoplesoft_result_page Please see
<a href="https://codex.wordpress.org/Debugging_in_WordPress">Debugging in WordPress</a>
for more information. (This message was added in version 4.3.0.)
in \wp-includes\functions.php on line 4231
```
I also tried putting it in a plugin in a different site where I have some shortcodes implemented that are working fine, but had the same issue. No idea what is going on.
Any advice or ideas are greatly appreciated. Thanks in advance. | Your shortcode callback function is incorrect:
```
add_shortcode('load_peoplesoft_result_page', 'load_peoplesoft_results()');
```
You've included the `()`, but only the function name should be passed:
```
add_shortcode( 'load_peoplesoft_result_page', 'load_peoplesoft_results' );
```
Note that the second argument of `add_shortcode()` is a "callable". This is a standard PHP feature, and you can read documentation for them [here](https://www.php.net/manual/en/language.types.callable.php). |
343,389 | <p>I am working on a WordPress that someone else started and then disappeared. She created a few custom content types and variables using different plugins and I now want to access the data sets in the functions she created for her template.</p>

] | I would like to read from a .css file and inject it as an inline style in wp\_head. it's possible?
i've tried this "[Add inline css to theme](https://wordpress.stackexchange.com/questions/263656/add-inline-css-to-theme)" solution but it doesn't do what I expect because I expect all the style to be injected into
`<style> [mystile.css] </style>`
and not
`<link href="[mystile.css]">` | You need to add your css to wp\_head. In order to do so, you need to get your dynamic CSS first, load in into a variable and then add that variable to the head output. Just like so:

Assuming you only want to pull anchor tags from the headings, you could do something like:
```
$blocks = parse_blocks( get_the_content() );
$block_ids = array();
function get_block_id( $block ) {

First 4 posts display correctly inside a div then, the next div displays only one post, then two more divs with correct count.
What the....? | For your clearfix wrapper you are doing it wrong. You have this:
```
$counter = 0;
while ( $loop->have_posts() ) : $loop->the_post();
if ($counter % 4 == 0) :
echo $counter > 0 ? "</div>" : ""; // close div if it's not the first
echo "<div class='clearfix'>";
endif;
// BUILDS INTERNAL DIVS
$counter++;
endwhile;
```
So you are opening the div for numbers 0 and multiples of the number 4. Then inside that statement you are only closing a div if the `$counter` is greater than 0. So you end up closing the div, then opening a new one that may not get closed.
You need to do two things. First, move the closing `div` to echo at the end of the `while` statement. Second, wrap the closing `div` in a different conditional. Here it is corrected:
```
$counter = 0;
while ( $loop->have_posts() ) : $loop->the_post();
if ($counter % 4 == 0) {
echo "<div class='clearfix'>";
}
// BUILDS INTERNAL DIVS
/**
* Closing div for loop
*
* $counter is more than 0 AND $counter plus 1 is multiple of 4
* OR $counter plus 1 is the total posts found (the plus 1 here is because we start with 0 which counts toward our total)
*/
if ( ($counter > 0 && ($counter+1) % 4 == 0 ) || ($counter+1) == $loop->found_posts ) {
echo "</div>";
}
$counter++;
endwhile;

343,542 | <p>I have an HTML form that is used to send messages to a back end server. When the user clicks the send button, it triggers a javascript that makes an Ajax call to WordPress which in turn, makes an API call to the back end server to send the message. This part works flawlessly. The server then responds with a string which I want to return to the javascript to display in the form.</p>
<p>For some reason, I can't get the return value to javascript. I've stripped my function down to bare bones as follows:</p>
<pre><code>function smsgte_admin_send() {
check_ajax_referer('smsgte_nonce', 'security');
$response = admin_server_send(filter_input(INPUT_POST, 'message', FILTER_SANITIZE_STRING));
$result = array (
//'response' => $repsonse,
'response' => 'just a response',
);
return $result;
}
</code></pre>
<p>The <code>admin_server_send</code> triggers the message being sent to the server. The message reaches the server, so that's working. I was questioning the response from the server, so I just populated my result array with a random string, but the javascript never receives the string.</p>
<p>The javascript code is:</p>
<pre><code>function smsgteAdminSend(button) {
var message = document.getElementById("smsgte_admin_message").value;
jQuery(document).ready(function ($) {
var data = {
'action': 'smsgte_admin_send',
'message': message,
'security': smsgte_Ajax.ajax_nonce,
};
jQuery.post(smsgte_Ajax.ajaxurl, data, function (response, status) {
document.getElementById("smsgte_admin_send_response").innerHTML = response.response;
});
});
}
</code></pre>
<p>Originally, I was sending the response as a string instead of a key/value pair, but that wasn't working either. Can't help think I'm missing something simple.</p>

] | I have an HTML form that is used to send messages to a back end server. When the user clicks the send button, it triggers a javascript that makes an Ajax call to WordPress which in turn, makes an API call to the back end server to send the message. This part works flawlessly. The server then responds with a string which I want to return to the javascript to display in the form.
For some reason, I can't get the return value to javascript. I've stripped my function down to bare bones as follows:
```
function smsgte_admin_send() {
check_ajax_referer('smsgte_nonce', 'security');
$response = admin_server_send(filter_input(INPUT_POST, 'message', FILTER_SANITIZE_STRING));
$result = array (
//'response' => $repsonse,
'response' => 'just a response',
);
return $result;
}
```
The `admin_server_send` triggers the message being sent to the server. The message reaches the server, so that's working. I was questioning the response from the server, so I just populated my result array with a random string, but the javascript never receives the string.
The javascript code is:
```
function smsgteAdminSend(button) {
var message = document.getElementById("smsgte_admin_message").value;
jQuery(document).ready(function ($) {
var data = {
'action': 'smsgte_admin_send',
'message': message,
'security': smsgte_Ajax.ajax_nonce,
};
jQuery.post(smsgte_Ajax.ajaxurl, data, function (response, status) {
document.getElementById("smsgte_admin_send_response").innerHTML = response.response;
});
});
}
```
Originally, I was sending the response as a string instead of a key/value pair, but that wasn't working either. Can't help think I'm missing something simple. | Returning the result array will only return to the PHP function calling it, instead you actually need to output it by echoing it, and in this case because it is an array, encoding it with JSON before outputting. So `return $result` becomes:
```
echo json_encode($result); exit;
```
and then add dataType to the javascript call so it can recognize the array data:
```
var data = {
'action': 'smsgte_admin_send',
'message': message,
'security': smsgte_Ajax.ajax_nonce,
'dataType': 'json'
};
```
