直接用下面的代碼,覆蓋dede中的login.php即可

<? 
require_once(dirname(__FILE__)."/../include/config_base.php"); 
require_once(dirname(__FILE__)."/../include/inc_userlogin.php"); 
if(empty($dopost)) $dopost=""; 
//-------------------------------- 
//登錄檢測(cè) 
//-------------------------------- 
if($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,$pwd); 
              //成功登錄 
              if($res==1){ 
                       $cuserLogin->keepUser(); 
                       if(!empty($gotopage)){ 
                               //header("location:$gotopage"); 
                               ShowMsg("成功登錄，正在轉(zhuǎn)向管理管理主頁(yè)！",$gotopage); 
                               exit(); 
                       } 
                       else{ 
                               ShowMsg("成功登錄，正在轉(zhuǎn)向管理管理主頁(yè)！","index.php"); 
                               //header("location:index.php"); 
                               exit(); 
                       } 
              } 
              else if($res==-1){ 
                      ShowMsg("你的用戶名不存在!",""); 
              } 
              else{ 
                      ShowMsg("你的密碼錯(cuò)誤!",""); 
              } 
     }//<-密碼不為空 
     else{ 
            ShowMsg("用戶和密碼沒(méi)填寫完整!",""); 
     } 

//<-驗(yàn)證用戶 
}
