There’s no caching system in WordPress core that would cause the issues you’re having. The post meta cache (WP_Object_Cache) is not persistent. Its purpose is to ensure that meta data is only loaded once per page, not every time get_post_meta(), for example, is used, but it does not cache those queries across page loads. Therefore … Read more
Back up your database first, then run this query in phpMyAdmin (or if you don’t have phpMyAdmin, run the query out of functions.php on an admin hook using $wpdb->query): UPDATE wp_postmeta SET meta_key = ‘_logo’ WHERE meta_key = ‘_thumbnail_id’ This will preserve all of the current IDs and just change the name of the meta … Read more
get_the_author_meta applies a filter get_the_author_{$field}, i.e. in your case it will be get_the_author_description: function stripp($value) { return str_replace(array(‘<p>’,'</p>’), ”, $value); } add_filter(‘get_the_author_description’, ‘stripp’); In case the p tag has attributes, you may have to modify the above accordingly, or use preg_replace.
Look a this code: if( isset( $_POST [ ‘add_like’ ] ) ){ $update = $like_value + ‘1’; update_post_meta($post_id, ‘_like_value’, $update, $like_value); } Because you’re using it in a loop, it gets output multiple times on a page with a different value for $post_id each time. So essentially you have this: if( isset( $_POST [ ‘add_like’ … Read more
Like almost all content in WordPress, a Media item (aka attachment) is stored in the wp_posts table, and its metadata is stored in the wp_postmeta table. The wp_postmeta data is linked to the post by the post ID. If the Media item is set as an attachment to a specific post, then inside the wp_posts … Read more
After some testing in WordPress v6.0.1, it seemed that: We need to set the (default/initial) type of the data.items to null instead of object. (and yes, the type must be set, or else the API response would be invalidated with many “undefined index” notices) For each item, i.e. an array in the oneOf or anyOf, … Read more
Regarding the metadata portion of your question…I wonder if you could use the exif_read_data function? https://www.php.net/manual/en/function.exif-read-data.php
How do I manage custom meta in post revisions in the Block Editor era?
You should be able to do this fairly easily with the save_post hook. When one of the child pages is saved your hook will fire and allow you to firstly check the post type, and then if the post is indeed a child of your main post, where you want to update the URL, version … Read more
that function is explained here and if I understand it right, it’s not quite THAT simple. To use it as a single line in functions, you would have to fill out all those variables. add_post_meta ( 7, ‘fruit’, ‘banana’ ) This would literally output only on the admin of Post ID 7, and it would … Read more
