DedeCMS不支持PHP5.3、5.4及以上版本后台500错误白屏的解决方法

天外飘仙

今天把系统换成了windows server 2008 r2 同时将PHP环境提升至PHP5.5版本，测试PHPinfo的时候一点问题都没有，但是登陆dede后台却显示500错误，这应该怎么解决呢？百度了一下发现dede不支持PHP5.3、PHP5.4及以上版本了，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
首先打开 include/userlogin.class.php这个文件，在287行到308行原内容如下：

1. @session_register($this->keepUserIDTag);
   
2. $_SESSION[$this->keepUserIDTag] = $this->userID;
   
3. @session_register($this->keepUserTypeTag);
   
4. $_SESSION[$this->keepUserTypeTag] = $this->userType;
   
5. @session_register($this->keepUserChannelTag);
   
6. $_SESSION[$this->keepUserChannelTag] = $this->userChannel;
   
7. @session_register($this->keepUserNameTag);
   
8. $_SESSION[$this->keepUserNameTag] = $this->userName;
   
9. @session_register($this->keepUserPurviewTag);
   
10. $_SESSION[$this->keepUserPurviewTag] = $this->userPurview;
    
11. @session_register($this->keepAdminStyleTag);
    
12. $_SESSION[$this->keepAdminStyleTag] = $adminstyle;
    
13. PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);
    
14. PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);

复制代码

替换成

1. if(empty($adminstyle)) $adminstyle = ‘dedecms’;
   
2. //@session_register($this->keepUserIDTag);
   
3. $_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag;
   
4. $_SESSION[$this->keepUserIDTag] = $this->userID;
   
5. //@session_register($this->keepUserTypeTag);
   
6. $_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag;
   
7. $_SESSION[$this->keepUserTypeTag] = $this->userType;
   
8. // @session_register($this->keepUserChannelTag);
   
9. $_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag;
   
10. $_SESSION[$this->keepUserChannelTag] = $this->userChannel;
    
11. //@session_register($this->keepUserNameTag);
    
12. $_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag;
    
13. $_SESSION[$this->keepUserNameTag] = $this->userName;
    
14. //@session_register($this->keepUserPurviewTag);
    
15. $_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag;
    
16. $_SESSION[$this->keepUserPurviewTag] = $this->userPurview;
    
17. // @session_register($this->keepAdminStyleTag);
    
18. $_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag;
    
19. $_SESSION[$this->keepAdminStyleTag] = $adminstyle;
    
20. PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);
    
21. PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);
