get_{$meta_type}_metadata

FILTER wp-includes\meta.php (ligne 664)

Short-circuits the return value of a meta field. The dynamic portion of the hook name, `$meta_type`, refers to the meta object type (blog, post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function. Possible filter names include:  - `get_blog_metadata`  - `get_post_metadata`  - `get_comment_metadata`  - `get_term_metadata`  - `get_user_metadata`
