数据修改成功后,页面显示的还是原来的数据

回复讨论(解决方案)

先检查发送表单后的数据:print_r($_POST); ,看看有没有把数据发送出去
然后去数据库里查看是否真的修改成功
最后看看你改的那条和你查的那条是不是同一条

你修改后有刷新下页面吗?

先清理一下浏览器缓存,再打开页面看看

楼主的意思是,数据库数据更新,但是页面数据未更新,是这个意思吗?
首先确认你是否修改成功。

我确认过,数据库已更新了,但是页面显示的还是原来的数据。

修改成功后用location跳转到这个地址试一试。

设置一下页面禁止缓存

<?php header("Pragma: no-cache"); ?>
