update_(meta_type)_metadata_cache filter-hook . WP 5.0.0
Short-circuits updating the metadata cache of a specific type.
The dynamic portion of the hook, $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.
Usage
add_filter( 'update_(meta_type)_metadata_cache', 'filter_function_name_255', 10, 2 ); function filter_function_name_255( $check, $object_ids ){ // filter... return $check; }
- $check(mixed)
- Whether to allow updating the meta cache of the given type.
- $object_ids(int[])
- Array of object IDs to update the meta cache for.
