add_{$meta_type}_metadata

FILTER wp-includes\meta.php (ligne 90)

Short-circuits adding metadata of a specific type. 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 hook names include:  - `add_blog_metadata`  - `add_post_metadata`  - `add_comment_metadata`  - `add_term_metadata`  - `add_user_metadata`
