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];
$cuserLogin=newuserLogin();
if(!empty($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();
}
}
elseif($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
}
?>
