php5.4 织梦dedecms后台登录空白问题

有不少喜欢尝新的朋友会碰服务器安装php5.4版本之后dedecms5.7登录后面一篇白茫茫的啊,像下雪一样,下面我们来看dedecms后台登录空白问题问题办法.
 
linux,php5.4,织梦dedecms后台登录空白.
 
原因:include/userlogin.class.php,里面有一个keepuser()函数,是用session_register来注册一个session变量,但是在php5.4中已经移除了这个功能,代码如下:
 
把:@session_register($this->keepUserIDTag);注释掉,然后改为:
 
if (!isset($_SESSION[$this->keepUserIDTag]))
 
如下:
 
if (!isset($_SESSION[$this->keepUserIDTag]))
 
//@session_register($this->keepUserIDTag);
 
我的修改前与修改后的代码.
 
解决方法:找开include/userlogin.class.php文件.查找以下内容:
 
@session_register($this->keepUserIDTag);
$_SESSION[$this->keepUserIDTag] = $this->userID;
@session_register($this->keepUserTypeTag);
$_SESSION[$this->keepUserTypeTag] = $this->userType;
@session_register($this->keepUserChannelTag);
$_SESSION[$this->keepUserChannelTag] = $this->userChannel;
@session_register($this->keepUserNameTag);
$_SESSION[$this->keepUserNameTag] = $this->userName;
@session_register($this->keepUserPurviewTag);
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;
@session_register($this->keepAdminStyleTag);
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);
PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);
替换成
global $admincachefile,$adminstyle;
if(emptyempty($adminstyle)) $adminstyle = ‘dedecms’;
//@session_register($this->keepUserIDTag);
$_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag;
$_SESSION[$this->keepUserIDTag] = $this->userID;
//@session_register($this->keepUserTypeTag);
$_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag;
$_SESSION[$this->keepUserTypeTag] = $this->userType;
// @session_register($this->keepUserChannelTag);
$_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag;
$_SESSION[$this->keepUserChannelTag] = $this->userChannel;
//@session_register($this->keepUserNameTag);
$_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag;
$_SESSION[$this->keepUserNameTag] = $this->userName;
//@session_register($this->keepUserPurviewTag);
$_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag;//开源软件:Cuoxin.com
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;
// @session_register($this->keepAdminStyleTag);
$_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag;
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);
PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);
