升级到php5.4：织梦cms安装完成后登录后台出现空白解决办法

从事php工作&＃xff0c;最近使用  php5.4 后发现织梦网的后台登陆显示空白。查找原因&＃xff0c;在php5.4的说明中看到了其取消了对session_register的支持。

解决方法&＃xff1a;找include/userlogin.class.php里面的keepuser()函数&＃xff0c;将其修改为以下代码即可

function keepUser(){

    if($this->userID !&＃61; &＃39;&＃39; && $this->userType !&＃61; &＃39;&＃39;){

                global $admincachefile,$adminstyle;

                if(empty($adminstyle)) $adminstyle &＃61; &＃39;dedecms&＃39;;

                if (!isset($_SESSION[$this->keepUserIDTag]))

                $_SESSION[$this->keepUserIDTag] &＃61; $this->userID;

                if (!isset($_SESSION[$this->keepUserTypeTag]))

                $_SESSION[$this->keepUserTypeTag] &＃61; $this->userType;

                if (!isset($_SESSION[$this->keepUserChannelTag]))

                $_SESSION[$this->keepUserChannelTag] &＃61; $this->userChannel;

                if (!isset($_SESSION[$this->keepUserNameTag]))

                $_SESSION[$this->keepUserNameTag] &＃61; $this->userName;

                if (!isset($_SESSION[$this->keepUserPurviewTag]))

                $_SESSION[$this->keepUserPurviewTag] &＃61; $this->userPurview;

                if (!isset($_SESSION[$this->keepAdminStyleTag]))

                $_SESSION[$this->keepAdminStyleTag] &＃61; $adminstyle;

                PutCOOKIE(&＃39;DedeUserID&＃39;, $this->userID, 3600 * 24, &＃39;/&＃39;);

                PutCOOKIE(&＃39;DedeLoginTime&＃39;, time(), 3600 * 24, &＃39;/&＃39;);

                $this->ReWriteAdminChannel();

                return 1;

        }else{

              return -1;

        }

}
