以一种形式插入和更新

Question

昨天我的问题是关于插入和更新的一种形式，我做了，但数据插入，当我点击编辑链接，它可以在displayp.php它显示所有数据的字段，但是当我更新任何数据，并点击提交按钮其不更新，但它下一次插入数据在数据库中，我在数据库中获取多个记录。其实我已经把插入和更新中，如果当我更新它不是在其他部分动，所以请帮我...条件谢谢..

Answer 1

昨天我回答你，但你不添加一个隐藏的输入带ID。你可以这样做吗？

insert and update in one form in php

而且，你怎么想象这后在GET？

if(isset($_GET['id'])) 
{ 

$id = $_GET['id']; 
if(isset($_POST['submit'])) 
{ 

* * * 
} 
}
