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

Filters whether to delete 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

$delete

Whether to allow metadata deletion of the given type.

$object_id

Object ID.

$meta_key

Meta key.

$meta_value

Meta value. Must be serializable if non-scalar.

$delete_all

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