use post meta in add_meta_boxes action
Is there any way to use get_post_meta within a function called by the add_meta_boxes action hook?
I only want to display the meta box if a specific post meta matches a regex, but so far, I have not idea how to do so. | You can not put condition in callback function as it will display the meta box without the HTML. Better you can wrap `add_meta_box()` in `if` condition.
If you are on post edit screen you can get the post id in this way.
$post_id = false;
if (!empty($_POST['post_ID'])) {
$post_id = $_POST['post_ID'];
} else if (!empty($_GET['post'])) {
$post_id = $_GET['post'];
}
if (get_post_meta($post_id, 'yourKey', true)) {
add_meta_box($id, $title, $callback, $screen, $context, $priority, $callback_args);

Are database queries created using WordPress filters protected from SQL injection?
I'm using the WordPress 'posts_where' filter (< to alter my queries as below:
function filter_my_search($where=''){
global $wpdb;
if(isset($_GET['q'])) {
$where .= 'AND (((' . $wpdb->posts . '.post_title LIKE "%'.$_GET["q"].'%") OR (' . $wpdb->posts . '.post_content LIKE "%'.$_GET["q"].'%")))';
}
return $where;
}
add_filter('posts_where', 'filter_my_search');
So a query is being run, and I'm intercepting the where clause, and adding an extra condition. Would that code be susceptible to SQL injection? | No! WordPress will **not** protect against SQL injection in this case. You need to do so yourself, using `$wpdb->esc_like` and `$wpdb->prepare`:
if ( isset( $_GET['q'] ) ) {
// WordPress forces magic quotes (god knows why), unslash it
$value = wp_unslash( ( string ) $_GET['q'] );
// Escape like wildcards so that MySQL interprets them as literals
$value = $wpdb->esc_like( $value );
// Create our "true" like query
$value = "%$value%";
// Now inject it safely
$where .= $wpdb->prepare(
" AND ( ( $wpdb->posts.post_title LIKE %s ) OR ( $wpdb->posts.post_content LIKE %s ) )",
$value,
$value
);

Insert media while posting is not working with new wordpress update
Insert media while editing or adding post is not working since the 4.1.2 update. But I can upload media through media manager itself.
I didn't change anything in the site today, only the automatic update to wordpress 4.1.2. But since then I found this issue.
And the funny thing is I have two instance of same wordpress site and both of them updated in the morning. But one is working as normal, but one is not working.
When I debug it with console I saw that the working instance is using `POST asynce-upload.php` while other one using `POST admin-ajax.php` to upload media.
Anyone has an idea about that ? | I disabled the `post thumbnail editor` plugin, then everything started to work again as normal.
But for the general advise for similar kind of issue is, disable your plugins one by one and test. Then you can find the plugin which is not compatible with wordpress update. So that you can disable that plugin at lease until it is giving new update.

What function publishes a post when you click the publish button?
I'm trying to track down an issue with a plugin. In vanilla WP when you are on the post edit screen (/wp-admin/post.php) what function is getting called to change the post status from draft to publish?
I've looked in that post.php and there is nothing that I'm seeing do it. I'm thinking that it may be some kind of AJAX call and I tried pausing execution to see what's happening when you click that button but I couldn't find anything. | Normally, posts are published by the `wp_insert_post()` function. Essentially, the `post_status` is changed from draft to publish. Nothing more to it than that, really.
There is also the `wp_publish_post()` function, which is really only used for scheduled posts. It does the basic job of transitioning a post from "future" to "publish", and also calls the same various action hooks that `wp_insert_post()` would normally call, so that plugins and other functions which take actions on publishing of posts behave correctly. | stackexchange-wordpress | {

Shared table across network
Im currently creating a plugin that will read an xml file and import the data into 4 tables on a wordpress multisite. the tables are rather large, with ALOT of columns, so the post table is not suitable for this task. Every "blog" on the network needs to be able to access the data from this table.
I have tried creating the tables by following the codex instructions here using the dbDelta function: <
but on a multisite this creates a set of tables for each "blog" in the network. This is redundant as the data would be identical across all the different table sets.
I have been googling around but can't really find a WordPress-way of doing this.
Does anyone have ideas as yo how this is best achieved? When the plugin is activated network-wide, it needs to create a single set of tables to be accessed from all the blogs in the network | Use `$wpdb->base_prefix . 'table_name'` as a table name when you want to create a table for the whole network, or when you want to run queries on it.
`$wpdb->base_prefix` is always the prefix for the current network’s main table. | stackexchange-wordpress | {

Custom JS on a specific page
So, I have the following custom JavaScript in a page. (Written exactly the way it shows, except the img src)
<script src="
<script>
jQuery("#first").click(function(){
jQuery("#second").trigger('click');
return false;
});
</script>
<a id="first" href="#"> <img src="demo"> </a>
So the by clicking "first" button, it will trigger "Click" on the second button. The functionality itself works (ie. the "second" button is triggered)
However all other JavaScript functions are not working.
I am guessing adding a custom JavaScript file directly into the page is not the best way.
I see that there are some plugins to add JavaScript in a post/page, but I am trying to avoid any unnecessary plugins.
What would be the best way to add the custom JavaScript without affecting other JavaScript functions? What am I doing wrong?
Thanks | First of all, you should declare your scripts using wp_enque_script.
Second, jQuery is loaded automatically in WordPress and is set to no conflict mode. See the documentation for how to link a script that depends on jQuery.
Lastly, if you want it to appear on just one page you have two options
1. In your `functions.php` file add a custom field to either enable this script on that page.
2. Manually insert it on a given page, again via `functions.php` To target only the home page `is_home()` but of course you could just reference a page by it's page_id like this `get_page( $page_id )`. | stackexchange-wordpress | {

How to list all names and descriptions of a custom taxonomy

Prevent CF7 attachment from being deleted
I am using a contact form 7 plugin for an inquiry form and sending the visitor 2 local files attached to the reply email. The function I used is this:
function my_dynamic_attachments($cf7)
{
$submission = WPCF7_Submission::get_instance();
$submission->add_uploaded_file('toe', get_template_directory().'/attachment1.pdf');
$submission->add_uploaded_file('ep', get_template_directory().'/attachment2.pdf');
}
add_action( 'wpcf7_before_send_mail', 'my_dynamic_attachments', 10 );
The problem I am facing is that the attachments are deleted from the server after the email is sent, thus they are not available for the next visitor. Is there any way to prevent this from happening?
Thank you in advance! | Looking at `submit()` in `WPCF7_Submission` we see a call to `remove_uploaded_files()` which has no filter to stop it. So apparently what you are trying to do isn't meant to be done by the author of CF7.
So apart from getting the author to include a hook there the only way I see is that you generate your file and then create a copy before adding it to the form submission so your original file stays. | stackexchange-wordpress | {

Get the number of posts in a named category, outside the loop
I've managed to do this from a `single.php` file, inside the loop, but now I need to do it from another page.
I need to find out how many live posts are in category named `every story` (slug is `everystory`). I am not inside the loop.
I just need the number, I don't need to output anything except the number. E.g `8`
I have tried searching for a way to gather category data just via the `category_name` (could be name, or could be slug, could even be by category `ID`) but everything I've found so far refers to using a specific `$post` var and finding it's category which isn't what I want to do.
Here is the example of what I used on the `single` post page:
$category = get_the_category();
$counter = $category[0]->category_count; | I'm a bit unsure of you are actually asking, so apologies if I understood it wrong.
You can use `get_category()` to get the category object and then just simply echo the `$count` property value
$cat_count = get_category( 'ID OR ROW OBJECT' );

Downloading Generated XML File
I'm making a Widget which presents users with categories as drop down list. When user selects category and press download, I want to get all posts under category and download them. I have faced a problem on downloading. I do something like
$xml = ''; //generated XML with Simple XML
header('Content-type: text/xml');
header('Content-Disposition: attachment; filename="text.xml"');
echo $xml->asXML();
I get headers already sent. So I added buffering to init with code:
add_action('init', 'do_output_buffer');
function do_output_buffer() {
ob_start();
}
and in my `MY_Widget::widget()` I add the code `echo ob_get_clean();` after `echo $xml->asXML();` explained above. Here it works except it exports whole page (with my XML) as single XML file.
Is there a way to download file without including whole page? | I just had to clean buffer and then do my stuffs and call exit
ob_clean(); //clear buffer
header('Content-type: text/xml');

Removing get_template_part in child theme
Parent Theme loads some template files in its functions.php as follows:
get_template_part ('lib/login/register.php');
I want to remove this file in child theme and include my custom php templates.
How can I remove get_template_part function from parent theme.
Thanks | Copy the file to your child theme,
In your child theme, create a template and name it what ever you want, e.g `content-child.php`
Now you can replace `lib/login/register.php` with your new template:
<?php get_template_part( 'content-child', get_post_format() ); ?>

When using W3 Total Cache should I remove my enqueues from functions.php
I am using W3 Total Cache, but when adding the stylesheets and scripts to cache I am not entirely sure whether I should remove those scripts from my functions.php enqueue list or not.
Also a small additional question. Is it a good idea to add Google Fonts to the cache _and_ minify them? | There is no need to deque CSS files and JS files from functions.php as W3Total Cache can be configured to combine all CSS files into one and later it in minified.However you must keep in mind that all CSS and JS files are combined serially(one after another , so you load them as per your theme requirements) and then minified into one.
Google fonts are not served from your own server,so, you can't really minify and concatenate it.Also, Googles font servers are probably faster than if you'd host the fonts yourself. | stackexchange-wordpress | {

Benefits of using Nav Walker?
Are there any benefits to using a nav walker class over iterating through wp_get_nav_menu_items()?
Nav walkers seem very clunky to me and iterating over an array feels easier and more re-usable but it then bypasses the internal menu filters of wordpress that I don't know much about. Will this make my theme incompatible with some plugins?
Best practice advice here would be greatly appreciated. | I would say mostly you see the usage of `wp_nav_menu()`, which does use `wp_get_nav_menu_items()`. You can use `wp_nav_menu()` with the default walker or a custom walker.
To be honest I can't remember the time I did a menu manually, with `wp_get_nav_menu_items()` or something else, and I tend to be lazy, so this is definitely more work.
The Walker Class gives you a lot of possibilities as there is more information available, which definitely is big plus. So whether you should leverage a walker - or otherwise (I'd say) use `wp_nav_menu()` \- is pretty much a question of what you need to achieve, for more complex menus I personally would always go with a walker. Last but not least, walkers are nicely reusable, which is pretty neat and another plus. | stackexchange-wordpress | {

Genesis / custom template page / setting the page title and meta desc
My WP site is running Genesis. I've just implemented my first custom page template in a child theme. The template runs some PHP and makes some data available to any page based on the template using shortcodes. All is working well, except...
For SEO, I'd like to set several items in the _head_ section - most importantly the page title but also some meta items. I use the Yoast Wordpress SEO and this section is top/tailed with a Yoast comment so perhaps it's taken charge of these fields.

When add_query_arg() is necessary?

return $vars;
}
add_filter( 'query_vars', 'add_custom_query_var' );
plugin_part1.php
...
echo '<a href="
...
plugin_part1-fixed.php
...
echo '<a href=" "custom_var", $db_table->db_column).'">text</a>....'
... | The difference is, in "plugin_part1-fixed.php" you wouldn't lose existing args. Consider the url:

<a href="
Note, the existing arg "foo" has been lost, the code in "plugin_part1-fixed.php" would output:
<a href="
Note, the existing arg "foo" is still present and your arg has been appended.
Since you don't have any existing args you don't see a difference. That said, using `add_query_arg()` is still best practice since you don't know if you'll have to interact with another plugin that might also be sending args for whatever reason.
Also, please keep in mind that you should always wrap `add_query_arg()` in `esc_url()` to prevent XSS scripting as better explained here. | stackexchange-wordpress | {

Custom Behavior when Adding New Custom Post Type in Dashboard
I have a Custom Post Type that I'm doing some custom work for. I want to attach some custom functionality to the post type once it's created but an admin can only trigger the custom action from the dashboard.
**For Example**
You create a new Post of the custom type and after it's created you can go to edit the post and in there you see a button that says "Custom Function" which will run some javascript.
**The Idea**
I need the custom button to run a function in functions.php which will create X amount of entries in a custom table on the mysql database and then return the values. I'll use an input next to the button to decide X's value.
I'll be fine with the php + sql + ajax but I just don't know a non-hack way to get the custom inputs to show up on the edit page. Any ideas? | Add a meta box to your custom post type edit screen to contain your markup. Check the `$pagenow` global to only show it on `post.php`, not `post-new.php`, and check `$current_user` global for administrator role to exclude other user roles.
Also, if you aren't familiar, check out the `$wpdb` class for your queries, and read up on using AJAX in WordPress.

Pushing Category and Publish Date to Google Analytics
I have found an interesting article about tracking variables with JS based statical system (for example Google Analytics).

_gaq.push('setCustomVar', 4, 'contCat','[CATEGORY NAME]',3);
_gaq.push('setCustomVar', 5, 'contSubCat','[SUB CATEGORY NAME]',3);
But how can I get the actual value of the pubdate from the PHP environment of Wordpress and write it in the HTML generated code so that it will be really made available to analytics? I hope the question is clear enough. | If you're printing your script inline (i.e. not in an external file), you can use PHP to dynamically output the JavaScript argument:
<script>
_gaq.push( 'setCustomVar', 3, 'pubDate', '<?php the_time( 'Ym' ) ?>', 3 );
</script>

$theme_name = 'themename';// this would be global var or var from a theme class
__('Background image', $theme_name); // or $myClass->themename

Do you see a problem with this ? | Yes this is problematic as i18n tools that parse your theme to generate a *.pot file for translation can't understand this as they do not run PHP code but just search your code as text.
Here is a blogpost detailing on why this may cause trouble:

New Menu Item Type Meta Box
I have a project I am working on where I need to pull in articles from a 3rd party API.
I've got this working using rewrites, but the last step I'm having trouble with is integration into the navigation.
What I'd really like is a separate meta box in the left hand column where I could ask for an article id and category and from that information add a custom link to the nav.
Is such a thing possible? I haven't seen much in the way of custom meta boxes from menu items.
Thanks, | Yes, this should certainly be possible, although as you have noticed it's not too common.
If you take a look at respective admin template the left column is built like this:

!pagesource screenshot | I managed to fix this issue by commenting out the first body tag and placing a second body tag below like this:

Answer from Kim Christensen :
<?php $content = get_the_content(); ?>
<?php printf(__('Output : %1$s', 'theme'), $content); ?>
Works perfectly :
Output : Foo
* * *
Answer from Pieter Goosen :
<?php $content = apply_filters( 'the_content', get_the_content() ); ?>
<?php printf(__('Output : %1$s', 'theme'), $content); ?>
It pushes my content below :
Output :
Foo | `the_content()` prints it output to screen. What you want is to return that output and assign a variable to it.
You should note, although `get_the_content()` do exactly what you want, it only returns unfiltered content, and not filtered content like `the_content()`. You should manually add those filters, which is real easy.
You can do the following
$content = apply_filters( 'the_content', get_the_content() );
## EDIT
It seems the above approach pushes the content part to the next line when the filters are applied to `get_the_content()`.
A work around here would be to concatenate `Output :` to `get_the_content()` and then applying the content filters to that
<?php $content = apply_filters( 'the_content', 'Output :' . get_the_content() ); ?>
<?php printf(__( '%1$s', 'theme'), $content); ?>
would give you what you need | stackexchange-wordpress | {

Why are these settings unregistered?
After updating a WordPress site to version 4.2 (and the forced 4.2.1 security update), I get some weird deprecated errors:
> Functionality: Unregistered Setting
>
> The `post-type-menu-page` setting is unregistered. Unregistered settings are deprecated. See < Deprecated in version 2.7.
I have the same error for lots of other post types: `post-type-dashboard-page`, `post-type-menu-post`, `post-type-menu-forum` (this is from bbPress), `post-type-dashboard-post` and more.
These errors have been reported by the Log Deprecated Calls plugin. There is no line or file shown.
Why do I get these errors?
I don't care about the native WordPress post types, I just want to fix my own post types to be up to date with 4.2+.
**EDIT:** Based on the option's structure, I couldn't find any reference both to `post-type-` or `post-type-menu-` in WordPress' source code. | The error message is actually misleading here. WP isn't checking if the settings are registered -- e.g., `if ( isset( $GLOBALS['wp_registered_settings']['foo'] ) )` \-- it's checking if the form was posted to the default options page (`options.php`), rather than a custom one (`options-general.php?page=foo`).
So, it's entirely possible to get this warning after calling `register_setting()`, if you're doing something like this:
`<form method="post" action="options.php">`
You can just remove the entire `action` attribute, since it'll post to the current URL by default. In that case, it'll include the `?page=foo` parameter, so `$unregistered` won't be set. | stackexchange-wordpress | {

Custom function causes a 503 error after a couple of hours
I have a custom function written in PHP for a Wordspress theme. When I initially wrote it, it worked exactly as expected (it returns the parents and grandparents etc of a term from its ID).
However, after a couple of hours, it started throwing up 503 errors. Why would this only happen after a while? Is there some sort of memory leak that builds up over time?
$ancestors = $terms[0]->term_id.GetAncestors($terms[0]->term_id,$include);

if($parent_term->parent!=11) {GetAncestors($parent_term->term_id,$include);}
return $include;
}

We can easily create a function to return a list by using `implode` to do so:

$object_id,
$object_type = 'category',
$separator = ','
) {
$ancestors_array = get_ancestors( $object_id, $object_type );

How to get_template_directory() properly on local environment
I'm currently developing a site locally in MAMP PRO. When I use get_template_directory() inside of the standard functions.php file, the site path gets output correctly. However, I have a separate enqueue.php file that I use to enqueue my scripts.

require get_template_directory() . '/inc/enqueue.php';

I can't seem to figure out why the /Users path gets added to the URL when I'm not in the functions file.

> (string) Absolute path to the directory of the current theme (without the trailing slash).
>

That is what you are seeing. The function works correctly (based on my interpretation of your question, anyway).
You want `get_template_directory_uri()` instead, which will give you a path relative to your web server root and which is what `get_bloginfo('template_directory');` gives you. | stackexchange-wordpress | {

How to conditionally pass a parameter to wordpress search to limit post types?

Log of Heartbeat Calls
I've read that Heartbeat can slow a WP site down and I'm assuming if our admins/store managers have a lot of admin windows/tabs open, this will exacerbate the issue.

How to load css in the footer

Someone could help me for find a smart solution? | Actually all styles should be placed in header.

So here is a way to to this: You can use `print_late_styles()` function which is called in footer. You just need to enqueue your styles when header is already passed.
So you need to find some hook which is called on each page and after `wp_head` hook. For example `get_footer` could be one.

wp_enqueue_style( 'your-style-id', get_template_directory_uri() . '/stylesheets/somestyle.css' );

Disable Admin Bar Render on Plugin Page

As such, any posts/pages created before the plugin was installed that haven't been viewed since will have no post meta. If you've been on the admin end of your dev server this entire time then it's possible there legitimately are no posts with any `views` post meta.

Note: these posts are already created and the author cannot be set upon creation. Another process is creating the post and defaulting to the admin as the author. I don't have access to creating the post but have access after it is created. | It shouldn't be any problem. Try this:

How to check if user meta field is empty in conditional else statement
Hello all I have a custom post type set up for my wordpress site within this custom post type i have a meta box with about 11 meta fields that I have added programatically. What I would like to do is check if one of the fields (which i have programmed to be a radio box)has a value if it does i would like to display the value of the field. If not then i would like to echo out the word Available. This is what I have been trying so far:
<?php
$consignment= get_post_meta($post->ID, 'availability', true);
if (empty ($consignment)) {
echo "avaliable";
} elseif ($consignment > 1) {
echo "$consignment";
}
?>
I would really appreciate the help. | Does this do the trick?

Wrapping add_query_arg with esc_url not working
I know about the XSS issue related to `add_query_arg()`function. That is why I am wrapping it with `esc_url()`.
Problem is...this is not working with `wp_remote_get()`.
If I go:
$url = add_query_arg( array( 'email' => '[email protected]',
'token' => '899A762614F6C49809A374FB955EC8C15'),
' );
$response = wp_remote_get( $url );
I am getting a valid body response.
But if I use esc_url on the `$url`:
$url = esc_url(add_query_arg( array( 'email' => '[email protected]',
'token' => '899A762614F6C49809A374FB955EC8C15'),
' ));
$response = wp_remote_get( $url );
The body response is "Unauthorized".
And the strange part: both codes echo the same string for $url!!!
Now what? | > And the strange part: both codes echo the same string for $url!!!
No, they don't. Look at the page source. `esc_url()` is encoding the `&` control character. You can't do that and expect the HTTP request to work correctly.
Use `esc_url_raw()` instead. Note the description in the Codex concerning that function:
> The esc_url_raw() function is similar to esc_url() (and actually uses it), but unlike esc_url() it does not replace entities for display. **The resulting URL is safe to use in** database queries, redirects and **HTTP requests**.

Broken urls with http site and https wp-admin
I am currently using a wordpress installation in which all the website is intended to be shown in http while the https part is protected by a self signed certificate, distributed manually to the admins. The problem I have is that the images uploaded are all uploaded with the "https" prefix, I imagine because the link is generated somehow using the full path of the admin interface. Do you know how I can fix this behaviour to use the protocol http for every image uploaded? I don't really need https for this and the site name and URL is in http.
Thanks in advance.
Some specs:
* wordpress version: 4.2.1
* plugins installed: Category Posts Widget, Jetpack, Post Types Order, Relative Image URLs, WordPress SEO, WP Statistics. | I figured out the problem: the SEO plugin by Yoast is breaking the images as described, doing (probably) a URL rewrite at the time the media is upload. I resolved temporarily bye disabling the plugin. I will then find a better solution analyzing why the plugin is behaving in such a way and update my answer. | stackexchange-wordpress | {

Custom term templates
So, I did some research online but could not find a solid answer, so here I am.
I am in need to make a custom woocommerce category page for a specific category.
For example, I have a category called "Awesome".
Instead of using a regular category page, generated by a shortcode`[product_category category="something"]`, I want to customized a specific category page for `Awesome`.
I found that I need to edit the `taxonomy-product_cat.php` file but I have no idea how to link it to the specific category called `awesome`.
In other words, I am thinking of making a custom copy of the php file then add it as a theme `template`.
Does anyone know how I can achieve it? | If you look at the template hierarchy, you need to create a template `taxonomy-{$taxonomy}-{$term}.php`. In your case, that template will be called `taxonomy-product_cat-awesome.php` where I assumed the **slug** of your term is `awesome`
Just a tip, the "categories" of a custom taxonomy is called `terms`. The build in taxonomy `category` "categories" is also called terms, but we call them in plain language categories. To understand this, you should check out this post | stackexchange-wordpress | {

Problem with Class, Filters and Callbacks
according to this Callback example if I'm referencing a method inside a class, I should use add_filter by specifying an array with 2 elements, first the object then the method. Here is my code:
add_action ('login_head', array('Admin', 'plugin_setup'));
class Admin
{
public function plugin_setup()
{
add_filter('login_headerurl', array($this, 'the_logo_url'));
}
private function the_logo_url()
{
return get_bloginfo('url');
}
unfortunately my code does not seem to work unless I move the function `the_logo_url()` outside the class. What's the best way of approaching this problem? | Here's a slightly modified version of your code snippet:
add_action( 'login_head', [ 'WPSE_Admin', 'plugin_setup' ] );
class WPSE_Admin
{
public static function plugin_setup()
{
add_filter( 'login_headerurl', [ 'WPSE_Admin', 'the_logo_url' ] );
}
public function the_logo_url()
{
return get_bloginfo('url');
}
}
The filter callbacks must be _public_ , not _private_. The reason for this is that `apply_filters()/apply_filters_ref_array()` are running `call_user_func_array()` on the stored filter callbacks, in the global `$wp_filter` array.
Also notice that you're not instantiating your `WPSE_Admin` class, so you can't use `$this`. You might want to use _namespace_ but I just prefix the class here. | stackexchange-wordpress | {

How can I add a new page in the pages tab that belongs to specific theme?
Hi I would like to add new pages in my active theme but I dont want these pages appears when I move or active another theme.
I know these pages are saved in the database, but how can I link them to a specific theme?
thanks in advance for your help... | Pages are an independent entity separate from whatever theme is active at that moment.
This is the design paradigm of most CMS systems that separate the concerns of site content from the view or rendering layer which allows a site owner the chance to change how his site looks without having to worry about the contents.
HOWEVER, it would theoretically be possible to build a plugin or simply hook into the template activation system within wordpress to activate or de-activate certain pages on the fly... Or the plugin could conditionally render menu's based upon the active theme slug. | stackexchange-wordpress | {

Separate the tag by comma
I am looking for a solution to separate the tag names by comma. The tag name i am using is without a link. Here goes the code:
<?php $my_tags = get_the_tags();?>
<?php echo $my_tags[0]->name?><?php $count=1;
foreach ($my_tags as $my_tag) {
if ($count != 1) {?>
<?php echo $my_tag->name?>
<?php }
$count++;
} ?>
The above code i got it from this page --> How to separate the tags?. But, the outcome is without a comma(,) if there are more than 1 tag.
Any solutions? Thanks! | This is actually more php related. Best will be to add your term names in an array and then use `implode` to convert it to a comma separated string

$tag_names[] = $tag->name;

Block access to wp-admin

allow from y.y.y.y

Safe to delete blank postmeta?
We have a lot of rogue custom fields. I feel that we can clear significant space in the DB if we remove the blank values. If I query my database with the following:
select * from wp_postmeta where meta_value = ''
I get 871038 (!)
My question is, is it safe to delete these? Are there any potential issues that could arise from doing this? | You should be fine deleting empty custom fields.
The main reason is, that `get_post_meta( $id, 'metakey', true )` returns an empty string if the field is not set, so it is the same as having an empty record set.
`get_post_meta( $id, 'metakey', false )`, returns an empty array if no value is set, so you should be fine too.
The only problem you could face is with getting all metadata at once (`get_post_meta( $id )`), because in the return to this call the empty values are set, but they are not set, if there is no record in the database. This could cause a few `PHP_WARNING`s, but you should be okay. | stackexchange-wordpress | {
