$profile_name是哪里来的？if (empty($name) || empty($pwd))
应该是if (!(empty($name) || empty($pwd)))吧if (!(empty($name) || empty($pwd)))
{
//查询数据库}
else
{
//用户名或密码为空，请重新输入
}

{
echo "<script language=javascript>alert('对不起帐号或者密码错误!');history.go(-1)</script>";
exit;
}?>
应该是:if (!(empty($name) || empty($pwd)))
或者if (empty($name) and empty($pwd))
$profile_pwd=$pwd;是不是应该是
$name=$profile_name;
$pwd=$profile_pwd;
