I did something like this once, but when you clicked on a certain category (essentially the same) It certainly isn’t a true ajax solution, it just hides and reveals the div with the settings, but It is a solution which works. You’ll definitely have to modify this for your needs, but if you have a … Read more

You can filter generated SQL and add precision parameters that you need. Enable filters for get_posts() by adding following to query: ‘suppress_filters’ => false, And: add_filter(‘posts_where’,’cast_decimal_precision’); function cast_decimal_precision( $where ) { return str_replace(‘DECIMAL’,’DECIMAL(10,3)’,$where); } Update With Jan’s suggestion: add_filter(‘get_meta_sql’,’cast_decimal_precision’); function cast_decimal_precision( $array ) { $array[‘where’] = str_replace(‘DECIMAL’,’DECIMAL(10,3)’,$array[‘where’]); return $array; }
Think I found the answer here. The first argument to register_meta is not post type but object_type, which is in my case should be post rather than taxonomy or comment. The function description, found here, states as of WordPress 4.9.2 the correct parameter is post.

Hmmm, can’t remember or find fitting function either. There is wp_set_object_terms() that is used in multiple wrappers like wp_set_post_categories(). It can overwrite categories for a post. So you can get post categories, check for unwanted one and write it back excluding unwanted in that case.
You can use wp_generate_attachment_metadata: This function generates metadata for an image attachment. It also creates a thumbnail and other intermediate sizes of the image attachment based on the sizes defined on the Settings_Media_Screen. The second argument of the filter is the attachment ID, so it shouldn’t be a problem to add the post meta: add_filter( … Read more
An attachment is a Post The posts table contains information on the attachment post. In WordPress every uploaded media has it’s own post entry, where post_type is ‘attachment’ and post_status is ‘inherit’. In fact, you can get attachment post types using functions used to get other post types, like post, page or any CPT. That … Read more
Short version: _encloseme is added to a post when it’s published. The wp-cron process should get scheduled shortly thereafter to process the post to look for enclosures. In other words, it cleans them up normally later. Nothing to worry about. Full explanation: “Enclosures” are links in a post to something like an audio or video … Read more
Try changing hierarchical: false in your CPT definition (if your application allows). When CPT’s are set to hierarchical: true all posts will be queried in the admin dashboard which can cause memory issues.
