我想根据包装页面上的packageId显示最后插入的数据。例如，在我编辑“黄金包装”后，系统会添加“黄金包装”的新数据并在“包装”页面上显示“黄金包装”的最后插入。但是我根据packageId列出数据，如何根据packageId列出数据？如何再次编辑金卡套餐的最后一个插入ID？

如果您不想在更新后丢失数据。您必须插入数据，例如没有更新的新数据，并且要选择最新的更新数据，必须使用时间，请创建两个新列update_id，current_time。像这样。
之后，如果要显示最近更新的数据，请使用Current_time选择类似的数据
$this->db->order_by('Current_time','DESC');
$data = $this->db->get('comment_update',1)->result_array();
