我在这个链接下有一个脚本Order list/ while loop php issue它从以下字段中检索订单数据行:
order_id | users_id | total | order_date(CURRENT_TIMESTAMP) | shipped
此后我添加了一个单选按钮，管理员用户可以单击该按钮以显示该商品是否已发货。 (它通过提交按钮向运送字段添加"is"或“否”)SQL 查询如下:
UPDATE orders SET shipped='$shipped' WHERE order_id='$id'
该脚本工作正常，但它将最初下订单的时间(在“order_date”下)替换为提交发货按钮的时间，我想保持原始时间不变。
我可以更改 SQL 查询还是必须为此使用 php？如果您需要查看完整的 PHP 代码，请告诉我。

最佳答案
@gview 是正确的，您应该更改您的表并将其设为 DEFAULT CURRENT_TIMESTAMP。如果您不能更改表，您可以更改更新查询以设置 order_date = order_date，这将阻止它被更新:
UPDATE orders SET shipped='$shipped', order_date = order_date WHERE order_id='$id'
