当我按下detail.php上的编辑链接时，它会显示data.php页面，其中填写了表格中的数据...现在如果我想编辑某些内容，然后按编辑按钮，它将是更新.. data.php 的代码给出如下

<?php if(isset($_GET['name']) && !empty($_GET['name'])):?>
<script>
window.onload=function()
{
document.getElementById("sbmt").style.visibility="hidden";

};              
function editform()
{

我需要这个地方的代码_它应该是什么？我想我需要ajax。当我按下编辑按钮时，它将是编辑记录，我在下面尝试了类似 bt 的内容，因为我需要值名称=??? 我怎样才能得到那个值_

<?php
$con=mysqli_connect("localhost","root","","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
   // mysqli_query($con,"UPDATE user_detail SET     name=,address=,gender=,hoby=,country=,place=,
    //WHERE name='$_GET['name']'");

mysqli_close($con);
?>
};                          
</script>
<?php
$con=mysqli_connect("localhost","root","","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
$p= $_GET['name'];
//echo "$p";
$result = mysqli_query($con,"SELECT * FROM user_detail where name ='$p' ");
$data =mysqli_fetch_array($result);
mysqli_close($con);
?>
<?php else:?>
<script>
window.onload=function()
{
document.getElementById("edit").style.visibility="hidden";

};
</script>

    <?php $data =array();?>
