            $db->insert('logs', array(
                'user'      => $_SESSION['user'],
                'action'          => $action,
                'values'       => json_encode($values),
                'row'         => $id,
                'date'         => date('d.m.Y')
            ));
}

            logChange($editor->db(), 'create', $id, $values);
        })
