解决方案 »

  1.   

    代码太多了,大致看了下,主要是LZ获取数据方面出问题了,把看到的几个问题标出来if($_POST['Submit']){
    $query=mysql_query("insert into tb_administrator (user,pass,qx)values('{$_POST['users']}','{$_POST['passs']}','{$_POST['pxs']}')");
    if($query==true){
    echo "<script>alert('普通用户创建成功!'); history.back();</script>";
    }
    }
    if($_POST['Submit3']=="创建"){if($_POST['Submit2']=="删除"){if($_POST['Submit4']=="修改"){
    问题比较多,LZ获取表单提交过来的数据,不要直接  $表单元素的name,这样获取不到的。
    如果是GET请求用$_GET['表单元素的name']
    如果是POST请求用$_POST['表单元素的name']

    或者统一用
    $_REQUEST['表单元素的name']
