 "" Then 
      Dim checkCode,sessionCode
      checkCode = Trim(Request.QueryString("checkCode"))
      sessionCode=Session("verifycode")
      
      '下面这两句是用来转换注册码全部为大写,可以方便用户输入
      checkCode=UCase(checkCode)
      sessionCode=UCase(sessionCode)


      If checkCode = sessionCode Then 
              Response.Redirect("http://www.hzynh.cn")''这里输入下载地址,验证成功后就可以跳转到下载地址
      Else 
             Response.Write("<script>alert('验证码错误,请重新输入');</script>") 
      End If 
End If

------解决方案--------------------
PHP code

<?php if (!empty($_REQUEST['submit']))
{
    $checkCode = strtoupper(trim($_REQUEST['checkCode']));
    $sessionCode = strtoupper($_SESSION['verifycode']);
    
    if ($checkCode==$sessionCode)
        echo "<script>window.location.href='http://www.hzynh.cn';";
    else
        echo "<script>alert('验证码错误,请重新输入');</script>";
}
?>
<br><font color="#e78608">------解决方案--------------------</font><br><?php <br />if(isset($_POST['submit']))<br>{<br>	$checkCode =Trim($_POST['checkCode']);<br>	session_start();<br>	$sessionCode=$_SESSION['verifycode'];<br>	session_destroy();<br>	$checkCode=UCase($checkCode);<br>   $sessionCode=UCase($sessionCode);<br>	if($checkCode == $sessionCode)<br>	{<br>		Header("Location:http://www.hzynh.cn");<br>	}<br>	else<br>	{<br>		echo "<script>alert('验证码错误,请重新输入');</script>";<br>	}<br>}<br>?><br><br>
<br><font color="#e78608">------解决方案--------------------</font><br>如果你读取的是 php 的session,那么你没有启用 session<br>缺少 session_start();<br><br>如果你试图读取 asp 的 session,那么对不起,你这样是读不到的 <div class="clear">
