apply_filters( "update_{$meta_type}_metadata_by_mid", null|bool $check, int $meta_id, mixed $meta_value, string|false $meta_key )

Short-circuits updating 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:

  • update_post_metadata_by_mid
  • update_comment_metadata_by_mid
  • update_term_metadata_by_mid
  • update_user_metadata_by_mid
