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
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.
Parameters
- $check
-
(null|bool) Whether to allow adding metadata for the given type.
- $object_id
-
(int) Object ID.
- $meta_key
-
(string) Meta key.
- $meta_value
-
(mixed) Meta value. Must be serializable if non-scalar.
- $unique
-
(bool) Whether the specified meta key should be unique for the object. Optional. Default false.
