$sql="select * from ot_user where UE_account='".$name."'"; 
$result=mysql_query($sql) or die("账号不正确");
$num=mysql_num_rows($result);
if($num==0){
// echo "<script>alert('帐号可以注册');location='?tj=register';</script>";
}
while($rs=mysql_fetch_object($result))
{

{
$_SESSION['ot_user']=$_POST['UE_account'];
echo "<script>alert('帐号已被注册!');location='?tj=register';</script>";

代码具体还没看  
不过你这个有很多问题  从产品角度说  你问什么不让人家设置一样的密码(随便练手可以无视)
复制到我本地一眼就看出来 最后一个大括号‘}’ 写成中文的了  这种程序能跑通么。。。没反应 你开调试报错了么

这个应该是我后面加上去的,改了之后还是不行的

大概看一下你的代码,一个form两个提交按钮,而且两个按钮没有区分为不同的操作,这个几个意思?不管你提交哪个按钮都是一样的post这个form里所有表单的数据。所以你一个按钮和两个按钮是一样的。你想要一个表格通过不同按钮提交之后又不同的操作得用到js,下面是我最近也的一个js不同按钮提交同一个表单进行不同操作的js,你可以参考一下(用jQuery库的js)
function ordersFormSubmit(href_link, form_action){
  actionPath = href_link+'&action='+form_action;
  $('#ordersForm').attr('action', actionPath);
  $('#ordersForm').submit();
}

Are there any alternatives to PHP sessions?Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
