这篇文章主要介绍了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,需要的朋友可以参考下
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] = $this->userID;
这种方式处理完整代码如下
首先打开 include/userlogin.class.php这个文件，在287行到308行原内容如下：
代码如下:
@session_register($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', $this->userID, 3600 * 24, '/'); PutCookie('DedeLoginTime', time(), 3600 * 24, '/'); 替换成
代码如下:
//@session_register($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, '/');本文转自 gutaotao1989 51CTO博客，原文链接:http://blog.51cto.com/taoyouth/2048738 转载地址：http://yijpx.baihongyu.com/
