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

Whether to allow adding metadata for the given type.

$object_id

Object ID.

$meta_key

Meta key.

$meta_value

Meta value. Must be serializable if non-scalar.

$unique

Whether the specified meta key should be unique for the object. Optional. Default false.
