老是提示验证码不正确,高手们帮我看看。
验证代码如下:
<?php
session_start();
include("conn.php"); //数据库连接
$CheckCode=$_POST['CheckCode'];
$username=$_POST['user_name'];
$password=$_POST['user_password'];
$sql="select * from [user] where username='".$username."'";
$rs=mssql_query($sql);
$row=mssql_fetch_row($rs);
if(strtolower($CheckCode)!=$_SESSION['authnum']){
echo "<script>alert('校验码不正确!');window.location.href='login.php';</script>";
exit;
}
if ($row>0)
{ if ($rs['password']==$password)
{$_SESSION['admin']="OK";
header("location:admin_index.php");
}
else echo"<script>alert('密码不正确!');window.location.hre
