Wordpress query posts with multiple post_meta data
I want to display posts in a slider that are marked as "featured".
For this i created a post meta box with a checkbox.
Now i have the following query
SELECT wp_posts.* FROM wp_posts, wp_postmeta WHERE wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = '' AND wp_postmeta.meta_key = 'theme_featured_post' AND wp_postmeta.meta_value = '1' AND wp_posts.post_status = 'publish' AND wp_posts.post_type = 'post' AND wp_posts.post_date < NOW() ORDER BY wp_posts.post_date DESC
But i need another value from the post_meta table as well. So how can I select the second meta_key in the query. I could query it with
> get_post_meta( $postid, 'custom_image')
Cause transactions are expensive, i would like to include it in one query.
The custom_image is an image id and has its own row in the table. | It's not a normal practice to use raw SQL in WP, unless you absolutely _have_ to. You should be using normal WP APIs for this and optimizing _after_ you encounter a performance issue.
Among other things APIs will transparently _cache_ data (such as post meta) within page load and between page loads with Object Cache installed. In typical cases Object Cache will be _faster_ than database fetch (which is the point of it). | stackexchange-wordpress | {

How to set a default value in a meta box
I found a post for adding units of measure after a price in woocomerce sites. It works wonderfully for me. Adding unit amount after WooCommerce price.
I want to add a default value since 95% of my products are all sq ft. Im hoping this will make it so all products show sq ft, but the few products I change to new values will have the new value displayed.
**Edit** Here is what I ended up using to accomplish this.
//add default of sq sf
add_filter('woocommerce_get_price_html','wpse103469_add_price_per_unit_meta_default');
function wpse103469_add_price_per_unit_meta_default( $price ) {
$default_units = __( 'sq. ft.', 'myplugin_textdomain' );
$units = get_post_meta( get_the_ID(), 'wc_price_per_unit_key', true );
return ( $units ) ? $price .= ' ' . $units : $price .= ' ' . $default_units;
} | Here's a tweaked version of the referenced `wpse103469_add_price_per_unit_meta_to_price()` function. If no units have been specified, the default units are appended to the price, otherwise the user-specified units are used.
add_filter('woocommerce_get_price_html', 'wpse103469_add_price_per_unit_meta_to_price');
function wpse103469_add_price_per_unit_meta_to_price( $price ) {
$default_units = __( 'sq. ft.', 'myplugin_textdomain' );
$units = get_post_meta( get_the_ID(), 'wc_price_per_unit_key', true );
return ( $units ) ? $price .= ' ' . $units : $price .= ' ' . $default_units;

Remove all removed pages from wordpress
I am creating a plugin in wordpress and the thing I am trying to do is to create pages with code using `wp_insert_post`.
After creating each page and removing all of them the new page with the same slug is being created with this format `slug-number`.
My question is how can I remove the page entirely from wordpress and database so each time a page is being created the previous one be deleted completely and the new ones slug become just the slug I provide without any number attached at the end of slug? | You must use `wp_delete_post()` with second parameter set to `true`. The post will be completely deleted, not trashed.
// Use $args to get the pages you created previously
// See
$pages = get_pages( $args );
if( $pages ) {
foreach( $pages as $page ) {
wp_delete_post( $page->ID, true );
}
}
After that, you can use `wp_insert_post()` to create a new post with a slug previously used.
It may worth to consider to update the post instead of delete and create a new one. | stackexchange-wordpress | {

How to use rewrite rule or rewrite endpoint to switch languages?
The goal is to have this working:
www.pageurl.de -> nothing happens
www.pageurl.de/en/ -> a variable is set and stored in a cookie
this also need to work with permalinks, categories etc. like this:
www.pageurl.de/en/linktopost/
www.pageurl.de/en/categoryname/
i tried to work with
`add_rewrite_endpoint('en',EP_PERMALINK|EP_PAGES|EP_ROOT|EP_CATEGORIES);`
but the endpoint (that makes sense) only works at the end of the url
i also tried to work with
`$language="en"; add_rewrite_rule('^' . $language . '/([^/]*)/?$', 'index.php?lang=$matches[1]', 'top'); ` but www.pageurl.de/en/ only returns a 404
What is the best way to do this?
I need to have the language pattern in the url on the whole page, lets say after changing the page in a menu the "en" has to be in the url. | You cannot do this by just adding a rewrite rule, you need to change every recorded rules.
Here is a simple way to do this:
function my_rewrite_rules($rules) {
$new_rules = array();
$new_rules['(?:de|en)/?$'] = 'index.php';
foreach ($rules as $key => $val) {
$key = '(?:de|en)/?' . $key;
$new_rules[$key] = $val;
}
return $new_rules;
}
add_filter('rewrite_rules_array', 'my_rewrite_rules', 11);
Now you still need a way to receipt the language value in order to save it in a cookie.
You could add a parameter for the language, in order to get it inside the `$_GET` super global. But that would means to offset all other parameters of all other rules, and this would involve a lot of regex.
Instead you can simply get the language by querying the `$_SERVER` global:
preg_match('/\/(de|en)(\/|$|\?|#)/', $_SERVER['REQUEST_URI'], $matches); | stackexchange-wordpress | {

Separate Custom Post Type Taxonomy by Comma

}
Each taxonomies show correctly. However, I cannot separate them in comma. it shows "TaxonomyATaxonomyB" but I want to show it as "TaxonomyA, TaxonomyB"
How to do it? or is there any other way around?
Thanks! | You can use a counter to determine if you need to add a comma or not :
$terms = get_the_terms( $post->ID , array( 'commitments', 'type' ) );

$term_link = get_term_link( $term, array( 'commitments', 'type' ) );

Use WordPress function in php file
I have a WordPress Child Theme and I have added a php file to this child theme. Also I want to use WordPress functions in this file ( I want to show header, menu and footer )
So I try
<?php
$parse_uri = explode( 'wp-content', $_SERVER['SCRIPT_FILENAME'] );
require_once( $parse_uri[0] . 'wp-load.php' );
?>
Also I try to add header and footer
<?php get_header();?>
//my content
<?php get_footer();
But it seems it can't load all css/js files and page have bad styling. | There are two things to do to make this work. First, you have to turn your php file into a template that can be recognized by WordPress. This is simply done by adding the following to the top of your file:
<?php /* Template Name: WPSE Example Template */ ?>
The second thing is, you must make sure this file is not called directly, but through WordPress, so functions like `get_header` are recognized. This you do by making a page in WP. You can leave everything blank, including the title. Just make sure that you assign your template as the one to be used by this page. Use the permalink generated when you save the page to display it. | stackexchange-wordpress | {

Localhost port is missing on some links after downgrading MAMP
I downgraded to MAMP after trying MAMP pro, everything is fine except some of the links don’t have localhost port; eg…localhost/about, when it should be localhost:8888/about. Some of the links include the port, and some don’t, but I’m not sure why? Any ideas would be greatly appreciated. Thanks! | If some of your link are using `localhost` while others are using `localhost:8888`, you'll want to make sure that all of the links in your database are set to `localhost:8888`.

2. Unzip the file and drop the folder in your **localhost** where your WordPress is installed (the root) and rename the folder to **`replace`** (screenshot)
3. Navigate to the new folder you created in your browser (ex: ` and you will see the search/replace tool

Creating Custom Hook for my plugin
In my plugin I have in admin menu function Media Organizations List. Here I get a list of all Organizations. There are 3 organizations types
* affiliate
* direct
* bureau
The total list will get long. Therefor I need a custom hook to filter the 3 organization types to get a better view.
I have read several documents but not understand exact what to do.
Is there someone of you who can help me making this custom hook? It would be very helpful. | First, register the filter hooks with the handy `apply_filters` tool:
function wpse_238394_org_types() {
return apply_filters(
"my_org_types",
array( "affiliate", "direct", "bureau" )
);
}

add_filter("my_org_types", function($types) {
$types[] = "custom_type";
return $types;
});

Changing WordPress routing to load the same page for different URLs

postsperpage value not being applied

Where is the correct place(s) in twentysixteen's header.php to add a Google webfont?
I have a slightly tweaked child theme to twentysixteen (used solely on ` \- feel free to view source!), and I would like to add a Google webfont. < suggests (as one option) to put e.g. `<link href=" rel="stylesheet">` before your theme imports its stylesheet. That sounds like sensible enough advice, but twentysixteen's `header.php` does not contain strings I could find like "css". As a result, I don't know where the last line is in `header.php` before the theme's stylesheet is loaded, or whether (in a child theme to twentysixteen) I should be editing some other file (and if so, which?).
I have provisionally placed `<link href=" rel="stylesheet" />` in `header.php` just after the open HEAD tag, but I suspect there are better or more surgical placements.
Where, in a twentysixteen child, should I place an HTML tag to import a Google font or the like?

My WP site and password was hacked, what to do?
Today I realized that my WordPress blog was hacked. I noticed, because the title was altered to something like:

After a while I couldn't login with my usual password, so I went to the host's cPanel and I tried to reset my WordPress password in the `wp_users` database, with the help of phpMyAdmin. There, I can see that somebody altered the login information to " _indoxploit_ " and maybe the password MD5 hash was also altered, because when I searched it in google I got this page hit:
Then I simply added a new MD5 hash and then I was able to login to my WP admin dashboard, I updated the WordPress version to the newest one, and the plugins too. What to do besides these actions? | Nice job recovering your password, however, the exploit probably still exists so you might get hacked again.

Advanced ordering of query_posts
I'm working on a rather large and old Wordpress project where someone has previously used `query_posts` all over the place. For this reason, I'm unwilling to change those method calls. I'm not the maintainer of the site, I'm doing a quick fix.
Each post in question has a field called `our_date`, which represents a date and a time, and `title`. The customer wants the posts ordered by `title`, but so that the _future_ posts appear first in the list and all the past dates at the bottom.
This is what I'm working with right now:
'orderby' => array('date' => 'ASC'),
What's the best way to accomplish this custom sorting of results from `query_posts`? | I don't think this is doable in a single WP API query. You just don't sort whole set with single logic, you have logic _changing_ halfway. I don't think even SQL can express this.
It is hard to advise without seeing specific circumstances (such as counts, pagination involved and so on), but my first thought would be to split this into two queries:
1. "Future" posts (meta query for date field in future, order by title)
2. "Past" posts (meta query for date field in the past, order by title) | stackexchange-wordpress | {

How to customize pagination links?
The default setup for `paginate_links` is very odd to me. For example if I'm on page 5 of a total of 9 pages, this is how it will display:

What I want to achieve is to display it something like Google search results page where I only show the current 5 (Google does 10) pages. I don't see any dots and I don't see the last page or the first pages unless I'm within that 5 page range. I want the user to click next as many times as needed to reach the end.

[1] 2 3 4 5 next >

Remove post type filter added by the plugin in the final query
I am querying the post types based on the custom post type, but when printing the final query it also includes the `post_type='tribe_events'`, which is due to plugin using for the events. But I have added the following parameters only in the query:
$args = array(
'post_type' => 'mycustomepost',
'posts_per_page'=>1
);
How to remove the events post type filter from the query? | The best course of action would be to prevent the plugin from doing something you don't want. If for some reason this is not possible you can use the filter `pre_get_posts` to change the query before it is executed, like this:
add_action( 'pre_get_posts', 'wpse239465_force_post_type', 9999);
function wpse239465_force_post_type () {
$query->set('post_type', 'mycustomepost');
}
Note that this will force the post type on all your queries, given that the priority of 9999 guarantees it is the last filter applied and there is no condition attached to `$query->set`. So you may at least want to add some conditional tag. | stackexchange-wordpress | {

Automatically Add Specified Value to Attachment Metadata upon Upload
I am trying to create a function that automatically adds a value to the attachment metadata (if it matters, on Audio uploads).
For example, I want to add a value of 'artist' and output it as my own specificity (for the sake of the example, just simply 'test')
I've tried numerous things but each one, thus far, has not worked (and outputs an unspecified error upon uploading the media).
Here's a couple things I've tried:
function auto_update_audio_meta($post_ID) {
add_post_meta( $post_ID, 'artist', 'test');
}
add_action('add_post_meta', 'auto_update_audio_meta');
I've also tried hooking to `update_post_metadata`, and variations such as
function auto_update_audio_meta() {
wp_update_post_meta( $post->ID, 'artist', 'test');
}
add_action('update_post_metadata', 'auto_update_audio_meta', 10, 5);
What am I doing wrong? | You're close! Try using these hooks instead.
// Add post meta to new audio uploads.
function auto_update_audio_meta( $post_ID ) {

add_post_meta( $post_ID, 'artist', 'test' );
}
}
add_action( 'add_attachment', 'auto_update_audio_meta' );

// Update post meta to updated audio uploads.
function auto_update_audio_meta( $post_ID, $post_after, $post_before ) {
if ( wp_attachment_is( 'audio', $post_ID ) ) {
update_post_meta( $post_ID, 'artist', 'test' );

Wordpress remove EXIF Data from specific Thumb
Is it possible to **hook** in to action when uploading and resizing specific size added by `add_image_size( 'mini-placeholder', 32 )` for image in Wordpress, and remove EXIF Data, and set quality of this one to minimum (10/20%)?
I want to achieve small thumb under 1kb (the goal is smallest as it is possible). | Assuming you are using ImageMagick (the WP standard) as your library there is a filter called `image_strip_meta` which controls whether the EXIF data must be preserved. Normally you would just use a boolean to do an overall setting, but you could easily make that a function like this:
add_filter ('image_strip_meta','wpse239481_conditional_strip')
function wpse239481_conditional_strip {
if (...condition ..) return true else return false;
}
The problem is in the condition. You would need to access the current thumbnail label, which doesn't trickle down from the multi_resize method that sets thing going. However, the target width and height are known in the resize function where the filter resides. Still, you can't access those dimensions inside the filter unless you hack the core to make this instance of `apply_filters` pass parameters.

How to catch and modify custom field values when a page is updated
I'm trying to find how to intercept the values in some custom fields on a page when they are being saved. I have searched and found out how to add a hook to the functions file to get the standard content fields, but so far haven't worked out how to do the same for custom fields. I'm using ACF Pro with flexible content fields, so the actual values come through as mutli-dimensional arrays.

}

}
add_filter( 'wp_insert_post_data', 'save_my_post' ); | It all depends on how your "custom fields" are saved.

Set Post Format if find a string in title or post content

if ( has_post_format( 'image', $postID ) || srtpos($a, 'imagenes') !== false)
return;
set_post_format( $postID, 'image' );
} | You are using `$post_id`, but you have passed the post ID as `$postID`. As a result `$a` is always empty.
Even if it weren't empty, there is no PHP function `srtpos`. It's `strpos` and you could have more straightforward logic to execute `set_post_format`.
Wrapping it up:
function CambiarPostFormat( $postID ) {
$a = get_the_title( $postID );
if ( !has_post_format( 'image', $postID ) && strpos($a, 'imagenes') !== false)

Custom Query to search through categories

A better way to override plugin's JS files?
I'm modifying some functionality of a theme i'm using, which already set up a `.js` file inside a plugin to handle the paypal checkout process. I had to modify the code so I renamed a few elements and basically copied the old js file to a new file and made the changes.
It works and everything is fine, but I wonder if there's a better way to do it in Wordpress? It doesn't feel right to modify so much just so I could change a few lines of code inside.
Thanks! | Extending the above comment:
Directly changing the files of the plugin or theme is not a good practice as once the plugin/theme is updated, you will loose the changes. Instead use child theme in case of themes and hook to required actions in case of plugins.
In your case since you are only changing the script in plugin and they might have enqueued(they should be) with `wp_enqueue_script` hooked to `wp_enqueue_scripts`. You can dequeue that script using `wp_dequeue_script` all you have to do is findout the script handle from the original plugin.

wp_get_post_terms() returns WP_Error in functions.php but in template it works
$my_post_id = 644;
$areas = wp_get_post_terms( $my_post_id, 'area-trabajo' );
var_dump($areas);
This code, in functions.php, returns:
object(WP_Error)#3178 (2) { ["errors"]=> array(1) { ["invalid_taxonomy"]=> array(1) { [0]=> string(20) "Taxonomia no válida" } } ["error_data"]=> array(0) { } }

What could be the reason that in the functions.php returns invalid_taxonomy? | If you dump the code into `functions.php`, then the custom taxonomy hasn't been registered, because it isn't recommend to register custom taxonomies earlier than the `init` hook.
Running the code within the template hierarchy files should work, because it's later than `init`.

Exclude posts from featuring

'posts_per_page' => 1,
'meta_key' => 'meta-checkbox',
'meta_value' => 'yes',

$query = new WP_Query( array( 'category__not_in' => array( 2, 6 ) ) );
See the codex: <
**NOTE: If you are trying to exclude category by the name of category**
First you would do this to find the category ID by providing category name.
$category_id = get_cat_ID( 'My Category' );
then add the returned `$category_id` in your WP Query arguments it would look like this:

Customize Wordpress Core Template
I used the `paginate_links()` function to retrieve pagination and everything works fine. It returns every link as `a` anchor tag it is also fine if we want links inside `<li></li>` we can specify return type as `array` and then loop to add links to `<li></li>`.
but what is the solution for current page link it return a span tag but i want wordpress to give me an anchor tag with `href="#"` attribute. i google but not find any solution instead i get understand from where this template is generating it's located in `general-template.php` file and it's easy to just replace html template there and that's it.
but it is not permanent solution nor good wordpress development.
**cons of doing so**
1) whenever wordpress will update my changes will lost.
2) it's not effective in just my theme it will disturb core template
anyone can help me out what is the better way to do so..? | Since it isn't pluggable, you could define a replacement function in your theme. In your theme's `functions.php` file, copy the core `paginate_links()` function, rename the function - perhaps `my_paginate_links()`, modify the source code so it creates the anchor tag you need, and then call your new function wherever you need it in the rest of the theme. | stackexchange-wordpress | {

Getting the ID of a meta box
I'm wanting to change the display title of a meta box when editing a custom post.
I want to try this solution here:
How to change the title of a Meta Box on a specified Custom Post Type?
Where I'd be removing the meta box and then re-adding it with a modified title. However, I don't have the ID information of my meta boxes and am having trouble finding them. Is there a way to get a list of ID's of meta boxes? I've looked into the global variable `$wp_meta_boxes`, but I couldn't figure out how to list the ID's.
A bit more information: I didn't create the meta boxes originally. I created custom taxonomies for a specific post type, and Wordpress automatically created the meta boxes that allow you to tag those custom taxonomies while editing my custom post. | Here's what I would do in order to get the ID of the metabox,
1. In the _Dashboard_ where the meta boxed are located, open up the _Screen Options_ tab on the upper right corner
2. Open up your browser's developer tool (ex: Chrome)
3. Use the element selector (![]( and select the checkbox label that is listed in the _Screen Options_ , like so:
![](
4. The element will be selected and you should see something similar:
![](
5. For each `<label for=` tag, you will find the ID's of each meta box, for example:
* `dashboard_right_now`
* `dashboard_activity`
* `dashboard_quick_press`
* `dashboard_primary`
* `wp_welcome_panel`
From there, you can continue with the code that you found in a previous question with the ID that you need. | stackexchange-wordpress | {

'Thumbnail' and 'Medium' Image sizes are different than expected
In a typical WordPress installation, the size of the `thumbnail` image is 150x150 and `medium` image is 600x400.
I'm theme developer and I have one client which has different sizes for these. The `thumbnail` size is 150x100 `medium` size is 300x200.
How can this be? Can this be overwritten in the WordPress core somewhere, or in the database?
My theme doesn't overwrite these but adds new/custom image sizes which shouldn't have any impact on the default ones.
I never faced this issue before. For all other clients, everything is working fine.
I would really appreciate some thoughts on this. | The `thumbnail`, `medium`, and `large` sizes can all be configured by the user under _Settings > Media_. Different installs can have different settings. The default size for the `thumbnail` size is 150x150, `medium` is 300x300, and `large` is 1024x1024. | stackexchange-wordpress | {

How to register script with null value for version?
Can someone explain the version argument in `wp_register_script()`? According to the codex it is `added to the URL as a query string for cache busting purposes`.
It also says if the `$ver` argument is set to `null`, no version is added and if `false`, the currently installed version of WordPress is added.
How do I set the `$ver` argument to `null`? I thought I had in the code I'm using below but it's adding the currently installed WordPress version as the version number.
function add_ajax_script() {
wp_register_script('ajax-implementation', '/wp-content/themes/codilight-child/scripts/ajax-implementation.js', array('jquery'), '', false);
wp_enqueue_script('ajax-implementation');
}
add_action( 'wp_enqueue_scripts', 'add_ajax_script' ); | You literally specify the version number as `null`:
function add_ajax_script() {
wp_register_script( 'ajax-implementation', get_stylesheet_directory() . '/scripts/ajax-implementation.js', array('jquery'), null, false);
wp_enqueue_script('ajax-implementation');
}
add_action( 'wp_enqueue_scripts', 'add_ajax_script' );

Favicon causes mixed content warning over SSL
I have the following favicon loading via header.php:
<link rel="shortcut icon" type="image/x-icon" href="<?php echo esc_url( home_url( '/wp-content/themes/themename/img/favicon.ico' ) ); ?>">
My site has an SSL certificate installed. Google Chrome loads the each page over SSL perfectly, but Firefox flags a mixed content warning. I can see via the source (both in Chrome and Firefox), that the favicon is being served via http.
I can't work out why this is happening. | After a little more reading via the WordPress Codex, I discovered that I was calling the favicon incorrectly. It should be called like this:

way to include own functions independent of theme
I know how to include my own functions by writing them into the theme's `functions.php` and enqueuing them, or by including a php file containing all that in `functions.php`.
But that is always bound to the used theme. If I switch to another theme, I always have to copy that code to the new theme's `functions.php`
Is there any way around that - a place/file where I can define and enqueue scripts that remain valid across all themes? (without loosing it when WP is updated)? | This is not quite simple (as copying and pasting into new functions.php :D), but you can create a plugin that will load this every time.
A (very) good and simple guide can be found here.
## Addition by Original Poster (johannes)
I created a plugin for that:
1. I created a simple php file and put it into `wp-content/plugins`. It looks basically like this (i.e. it contains the plugin name, description, author etc. and the function I want to use in my site across all themes):
<?php
/**
* Plugin Name: Function-Includer
* Plugin URI: my URI
* Description: my description
* Version: 1.0
* Author: johannes
* Author URI: my URI
*/
[... code of my function ...]
?>
2. Then I went into the WP admin backend, to the plugin page, where that plugin is listed as "Function-Includer" and activated it.
3. Done - the function is available everywhere in my site now. | stackexchange-wordpress | {

Certain header elements not served over https
I have forced SSL on each page of my site using WordPress HTTPS. This works perfectly and isn't throwing up any mixed content warnings.
However, when I visit the page source, I can see a whole bunch of resources being served over http in the header. These are not resources that I control, but what I assume to be coming from the WordPress core. Here they are:
<link rel="profile" href="
<link rel="alternate" type="application/rss+xml" title="Website » Feed" href=" />
<link rel="alternate" type="application/rss+xml" title="Website » Comments Feed" href=" />
<link rel=' href=' />
<link rel='shortlink' href=' />
<link rel="alternate" type="application/json+oembed" href=" />
<link rel="alternate" type="text/xml+oembed" href=" />
What are these elements doing and should I be concerned that they are not being served over https? | I'm not sure about the first one, the profile, but the `rel="alternate"`s and the `rel='shortlink'` provide different formats for different readers, like XML and RSS feeds. These should be generated by your site URL. In your dashboard, go to Settings > General, and make sure you're using https:// instead of http:// in the URL. You may then need to clear your site cache to see the change. | stackexchange-wordpress | {

Synchronise Renewals on existing subscriptions
I have a site that uses woocommerce together with subscriptions plugin. And I have recently turned on "Synchronise Renewals", I see that it works great for new people signing up for a subscription. But the previous subscriptions are not renewing to the specific day, but is renewing on the same day they signed up..
How can i make my precious subscriptions renew on the same day?
Would a solution be to manually change the date in "Next payment" field in the Billing schedule box on each subscription? Will that make it renew every monday if the date is on a monday? | Yes a solution for this is to manually change the date in "Next payment" field in the Billing schedule box on each subscription
A subscription can be unsynchronized by changing the next payment date to a day not aligned with the synchronization schedule. For example, changing a weekly subscription synchronized to Mondays to have the next payment processed on Wednesday will mean all future payments will be processed on Wednesday. This is because future payments are calculated based on the past payment and renewal synchronisation is only calculated and applied to the first payment. | stackexchange-wordpress | {

Trying hard but can't hide featured post/page from grid

if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post(); ?>

if(have_posts()) : while(have_posts()) : the_post();
?> | wp section of stackexchange really seems half dead.
you rarely get issue sorted.
have_posts checks whether there is any post, so add another condition that checks whether the post is featured or not.

Read More showing only on first post
I created a new menu item which only pulls posts categorized “Webinars” but when I visit the Webinar category page, only the first post excerpt gets a “Read More” button.
What do I have to do so that all post excerpts in this blog category get a “Read More” button? | There are only 2 posts on that page, so there's not a lot to go on here, but it looks like there is not enough text to warrant a _Read More_ button for the second post.
By default, WordPress has an excerpt length of 55 words (looks like that's in effect on your site). The second post isn't long enough to have an excerpt so the full post is shown.
You can change the number of words in the excerpt to something shorter. Add this code to your theme's `functions.php` file:
/**
* Filter the except length to 20 words.
*
* @param int $length Excerpt length.
* @return int (Maybe) modified excerpt length.
*/
function wpse240108_custom_excerpt_length( $length ) {
return 20;
}
add_filter( 'excerpt_length', 'wpse240108_custom_excerpt_length', 999 );

$dom = new DOMDocument;
$dom->loadHTML( mb_convert_encoding( $author_desc, 'HTML-ENTITIES', 'UTF-8' ) );

The function update_post_meta() updates the value of an existing meta key (custom field) for the specified post.
**This may be used in place of add_post_meta() function.** The first thing this function will do is make sure that $meta_key already exists on $post_id. If it does not, add_post_meta($post_id, $meta_key, $meta_value) is called instead and its result is returned.
Returns meta_id if the meta doesn't exist, otherwise returns true on success and false on failure. It also returns false if the value submitted is the same as the value that is already in the database. | stackexchange-wordpress | {

echo '<p>this post does not have a featured image</p>';
}
}
} else {
echo '<p>No post images found</p>';
}
Anybody knows a fix for that problem?
By the way I am using a Shortcode to get $name and $taxonomy | If your category is custom taxonomy you'll have to use tax_query in you `WP_Query()`.

'posts_per_page' => 6,
'post_type' => 'video',

array(
'taxonomy' => $taxonomy,

Promoting child theme to stand alone
I have developed a website using a fully fledged theme packed with tons of bloatware and custom functions/widgets I am not using. The package is slow, and 95% of CSS (1MB!!!!) and Javascript is never used by the child theme. This is why I am thinking about unlinking the child theme from the parent and promote the child theme as a standalone theme. However this requires "walking" through PHP code, scripts and CSS to verify what is being used before trimming.
What steps would you take, generally speaking, to achieve this? | Start with "view source" of rendered HTML and then work backward from that, building a new theme by pulling whatever css, php files and functions from the parent as needed.
