這篇文章主要介紹了DedeCMS不支持PHP5.3、5.4及以上版本后臺500錯(cuò)誤白屏的解決方法,需要的朋友可以參考下

今天把系統(tǒng)換成了windows server 2008 r2 同時(shí)將PHP環(huán)境提升至PHP5.5版本，測試PHPinfo的時(shí)候一點(diǎn)問題都沒有，但是登陸dede后臺卻顯示500錯(cuò)誤，這應(yīng)該怎么解決呢？百度了一下發(fā)現(xiàn)dede不支持PHP5.3、PHP5.4及以上版本了，主要原為是php5.4的版本廢除了session_register函數(shù) 

可以采用如$_SESSION[$this->keepUserIDTag] = $this->userID;

這種方式處理完整代碼如下

首先打開 include/userlogin.class.php這個(gè)文件，在287行到308行原內(nèi)容如下：

代碼如下:

@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

代碼如下:

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, ‘/’);
