apply_filters( "add_{$meta_type}_metadata", null|bool $check , int $object_id , string $meta_key , mixed $meta_value , bool $unique )
Filters whether to add metadata of a specific type.
Description Description
The dynamic portion of the hook, $meta_type, refers to the meta object type (comment, post, term, or user). Returning a non-null value will effectively short-circuit the function.
