直接用下面的代码,覆盖dede中的login.php即可
复制代码 代码如下:
<?
require_once(dirname(__FILE__)."/../include/config_base.php");
require_once(dirname(__FILE__)."/../include/inc_userlogin.php");
if(empty($dopost)) $dopost="";
//--------------------------------
//登录检测
//--------------------------------
if($dopost=="login")
{
  if(empty($validate)) $validate=="";
  else $validate = strtolower($validate);

  if( empty($_SESSION["s_validate"]) ) $svali = "";
  else $svali = $_SESSION["s_validate"];

   $cuserLogin = new userLogin();
     if(!empty($userid)&&!empty($pwd))
     {
              $res = $cuserLogin->checkUser($userid,$pwd);
              //成功登录
              if($res==1){
                       $cuserLogin->keepUser();
                       if(!empty($gotopage)){
                               //header("location:$gotopage");
                               ShowMsg("成功登录，正在转向管理管理主页！",$gotopage);
                               exit();
                       }
                       else{
                               ShowMsg("成功登录，正在转向管理管理主页！","index.php");
                               //header("location:index.php");
                               exit();
                       }
              }
              else if($res==-1){
                      ShowMsg("你的用户名不存在!","");
              }
              else{
                      ShowMsg("你的密码错误!","");
              }
     }//<-密码不为空
     else{
            ShowMsg("用户和密码没填写完整!","");
     }

//<-验证用户
}
