Filters whether to delete metadata of a specific type.

Syntax Syntax

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

Description 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 Parameters


Whether to allow metadata deletion of the given type.


ID of the object metadata is for.


Metadata key.


Metadata value. Must be serializable if non-scalar.


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