Filters whether to add metadata of a specific type.

Syntax Syntax

apply_filters( "add_{$meta_type}_metadata", null|bool $check, int $object_id, string $meta_key, mixed $meta_value, bool $unique )

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.
