apply_filters( "get_{$meta_type}_metadata", null|array|string $value, int $object_id, string $meta_key, bool $single )

Filters whether to retrieve 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.

    Note that although this filter filters the value that will be returned, you do not receive the current value as the first parameter.

    You allways receive null in the first parameter.

    If your callback returns anything else than null, this is the value that the function will return at the end. If you return null, the function will continue to run normally and try to fetch the data from the database (or cache).
