PHP 5.4相對與5.3的變化還是很大的，廢除了不少原因的函數(shù)，這也導致了一些CMS無法完美支持的問題，比如DedeCMS系統(tǒng)。

在PHP 5.4下，登錄DedeCMS后臺輸入用戶名和密碼后沒有提示顯示為空白，主要原為是php5.4的版本廢除了session_register函數(shù)?？梢圆捎萌?_SESSION[$this->keepUserIDTag] = $this->userID; 這種方式處理完整代碼如下：

解決方法一：

打開 include/userlogin.class.php這個文件，在287行到308行原內(nèi)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, ‘/’);

替換成

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, ‘/’);

至此問題解決。

解決方法二：

找到include文件夾中的userlogin.class.php文件中把所有帶有session_register的全部刪除即可。

@session_register下的所有語句屏蔽掉

function keepUser()

{

if($this->userID != ” && $this->userType != ”)

{

global $admincachefile,$adminstyle;

if(empty($adminstyle)) $adminstyle = ‘dedecms’;

代碼如下復制代碼

$_SESSION[$this->keepAdminStyleTag] = $adminstyle;

PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);

PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);

$this->ReWriteAdminChannel();

return 1;

}
