DedeCMS 5.7不兼容PHP 5.4版本的解决办法

PHP 5.4相对与5.3的变化还是很大的，废除了不少原因的函数，这也导致了一些CMS无法完美支持的问题，比如DedeCMS系统。

在PHP 5.4下，登录DedeCMS后台输入用户名和密码后没有提示显示为空白，主要原为是php5.4的版本废除了session_register函数。可以采用如$_SESSION[$this->keepUserIDTag] = $this->userID; 这种方式处理完整代码如下：

解决方法一：

打开 include/userlogin.class.php这个文件，在287行到308行原内容如下：

@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(empty($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;
$_SESSION[$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, ‘/’);

至此问题解决。

解决方法二：

找到include文件夹中的userlogin.class.php文件中把所有带有session_register的全部删除即可。

@session_register下的所有语句屏蔽掉

function keepUser()
{
if($this->userID != ” && $this->userType != ”)
{
global $admincachefile,$adminstyle;
if(empty($adminstyle)) $adminstyle = ‘dedecms’;
代码如下复制代码
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);
PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);
$this->ReWriteAdminChannel();
return 1;
}
else{….以下省略
