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
What you propose would break a lot of plugins and internals of WordPress. Post meta keys are not unique. This is supported at the API level too: // on save… add_post_meta( $post_id, ‘lead’, ‘Tom’ ); add_post_meta( $post_id, ‘member’, ‘Bob’ ); add_post_meta( $post_id, ‘member’, ‘Janet’ ); add_post_meta( $post_id, ‘member’, ‘Alice’ ); add_post_meta( $post_id, ‘member’, ‘David’ ); … Read more
I think the problem might be that the spread operator is missing in a couple of places. This line: return { meta: { currentMeta, editedMeta }, }; in withSelect should be: return { meta: { …currentMeta, …editedMeta }, }; This makes the meta object be a copy of currentMeta (have all the same properties and … Read more
Basically, you’re not properly using array_push(). array_push() modifies the original/input array which is passed by reference to the function and it returns the new number of elements in the array. So with add_post_meta( $groupItem->ID, $meta, array_push( $user_ids, 26 ) ), you’re actually setting the meta value to the number of items in $user_ids and not … Read more
If you’re hooking into publish_post, that fires before meta is ready. Either get the meta from the POST object, or use a different hook – possibly update_post_meta.
