apply_filters( "delete_{$meta_type}_metadata", null|bool $delete, int $object_id, string $meta_key, mixed $meta_value, bool $delete_all )

Short-circuits deleting metadata of a specific type.

Description

The dynamic portion of the hook, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function.

Parameters

$delete

(null|bool) Whether to allow metadata deletion of the given type.

$object_id

(int) ID of the object metadata is for.

$meta_key

(string) Metadata key.

$meta_value

(mixed) Metadata value. Must be serializable if non-scalar.

$delete_all

(bool) Whether to delete the matching metadata entries for all objects, ignoring the specified $object_id. Default false.
