文档:

Short-circuits deleting metadata of a specific type by meta ID.

The dynamic portion of the hook name, $meta_type, refers to the meta object type (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:

  • delete_post_metadata_by_mid
  • delete_comment_metadata_by_mid
  • delete_term_metadata_by_mid
  • delete_user_metadata_by_mid
