get_metadata( string $meta_type, int $object_id, string $meta_key = , bool $single = false ): mixed

Retrieves the value of a metadata field for the specified object type and ID.


If the meta field exists, a single value is returned if $single is true, or an array of values if it’s false.

If the meta field does not exist, the result depends on get_metadata_default() .
By default, an empty string is returned if $single is true, or an empty array if it’s false.
