不能删除指定的语句 总是从最后一个开始删除 奇怪啦
[code=PHP][/code]

form id="form1" name="form1" method="post" action="lianxi_ok.php">

  <table width="75%" align="center">
  <tr bgcolor="#0033CC">
  <td width="24%" align="center">QQ</td>
  <td width="32%" align="center">电话</td>
  <td width="24%" align="center">地址</td>
  <td width="32%" align="center">作者</td>
  <td width="15%" align="center">删除</td>
  </tr>
<?php
include("../conn.php");
$arr=mysql_query("select * from lianxi",$conn); //查询数据
/*使用while语句循环mysql_fetch_array()函数返回的数组*/
while($result=mysql_fetch_array($arr)){
?>
  <tr>
  <td><?php echo $result['QQ'];?></td>
  <td><?php echo $result['tel'];?></td>
  <td><?php echo $result['add'];?></td>
  <td><?php echo $result['zuozhe'];?>
  <input type="hidden" name="id" value="<?php echo $result['id'] ;?>" />
  </td>
   
  <td align="center"><label>
   
  <input name="Submit" type="submit" value="删除" />
  <a href="lianxup.php?id=<?php echo $result['id'];?>">编辑</a>
  </label></td>
  </tr>
<?php
  } //结束while循环
?>
  </table>
  
</form>

------解决方案--------------------

PHP code

include("../conn.php"); //包含conn.php文件
if(isset($_GET['id'])){
    $delete=mysql_query("delete from lianxi where id='".$_GET['id']."'",$conn);
    if($delete){
        echo "<script> alert('删除成功!'); window.location.href='index.php'</script>";
    }else{
        echo "<script> alert('删除失败!'); window.location.href='index.php'</script>";
    }
}
