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:

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, ‘/’); 
15. 替换成 
16. global $admincachefile,$adminstyle; 
17. if(emptyempty($adminstyle)) $adminstyle = ‘dedecms’; 
18. //@session_register($this->keepUserIDTag); 
19. $_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag; 
20. $_SESSION[$this->keepUserIDTag] = $this->userID; 
21. //@session_register($this->keepUserTypeTag); 
22. $_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag; 
23. $_SESSION[$this->keepUserTypeTag] = $this->userType; 
24. // @session_register($this->keepUserChannelTag); 
25. $_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag; 
26. $_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
27. //@session_register($this->keepUserNameTag); 
28. $_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag; 
29. $_SESSION[$this->keepUserNameTag] = $this->userName; 
30. //@session_register($this->keepUserPurviewTag); 
31. $_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag;//开源软件:Vevb.com 
32. $_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
33. // @session_register($this->keepAdminStyleTag); 
34. $_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag; 
35. $_SESSION[$this->keepAdminStyleTag] = $adminstyle; 
36. PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’); 
37. PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);
