update_(meta_type)_metadata_cache хук-фильтрWP 5.0.0

Short-circuits updating the metadata cache of a specific type.

The dynamic portion of the hook name, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function.

Possible hook names include:
