dede织梦会员登陆后如何返回登录前页面？

如果是DEDE的商品模型的话,你打开plus/carbuyaction.php

找到if(empty($username) || $password)

有两处,

替换为

			$gourl=urlencode(GetCurUrl());
            $gourl="/member/login.php?gourl=".$gourl."";
            if(empty($username) || $password)
            {
                $gourl = str_replace('^','&',$gourl);
                ShowMsg("请选登录",$gourl,0,2000);
				exit();
            }

/member/index_do.php找到

if(empty($gourl) || preg_match("#action|_do#i", $gourl))

替换为

if(empty($gourl))

搞定
