delete_{$meta_type}_metadata_by_mid WordPress Filter Hook
The delete_{$meta_type}_metadata_by_mid hook is called when deleting metadata by meta ID. This hook can be used to perform cleanup when metadata is deleted. For example, if you are storing metadata in a custom table, you can use this hook to delete the corresponding data from your table.
apply_filters( "delete_{$meta_type}_metadata_by_mid", null|bool $delete , int $meta_id ) #
Short-circuits deleting metadata of a specific type by meta ID.
Description
