解决更换PHP5.4以上版本后Dedecms后台登录空白问题的方法,php5.4dedecms
把PHP的版本从5.2.14升到了5.4.15,升级完后dedecms后台却打开空白,检查了各种权限和文件,都没有问题,找来找去,原来是PHP版本函数的问题,它是用session_register来注册一个session变量,但是在php5.4以上中已经移除了这个功能
解决办法:
找到include/userlogin.class.php,里面有一个keepuser()函数,它是用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,见官网介绍:
如果使用的该php版本肯定会出错的,不过我们可以修改下代码:
把@session_register($this->keepUserIDTag); 注释掉,然后改为
if (!isset($_SESSION[$this->keepUserIDTag]))
一共有六个,全部改为下面这样:
if (!isset($_SESSION[$this->keepUserIDTag])) //@session_register($this->keepUserIDTag); $_SESSION[$this->keepUserIDTag] = $this->userID; if (!isset($_SESSION[$this->keepUserTypeTag])) //@session_register($this->keepUserTypeTag); $_SESSION[$this->keepUserTypeTag] = $this->userType; if (!isset($_SESSION[$this->keepUserChannelTag])) //@session_register($this->keepUserChannelTag); $_SESSION[$this->keepUserChannelTag] = $this->userChannel; if (!isset($_SESSION[$this->keepUserNameTag])) //@session_register($this->keepUserNameTag); $_SESSION[$this->keepUserNameTag] = $this->userName; if (!isset($_SESSION[$this->keepUserPurviewTag])) //@session_register($this->keepUserPurviewTag); $_SESSION[$this->keepUserPurviewTag] = $this->userPurview; if (!isset($_SESSION[$this->keepAdminStyleTag])) //@session_register($this->keepAdminStyleTag); $_SESSION[$this->keepAdminStyleTag] = $adminstyle;
重新进入后台登录,就可以正常跳转到管理页面了。
因为对PHP并不熟,网上一般都说是data/common.inc.php文件编码的问题,把编码要改为无BOM格式文件保存,居然没有说是php5.4版本的问题
另外一种方法:
在include/helpers/util.helper.php末尾加入以下代码
function fix_session_register(){ function session_register(){ $args = func_get_args(); foreach ($args as $key){ $_SESSION[$key]=$GLOBALS[$key]; } } function session_is_registered($key){ return isset($_SESSION[$key]); } function session_unregister($key){ unset($_SESSION[$key]); } } if (!function_exists('session_register')) fix_session_register();
这样php5.4下dedecms就能正常使用了,希望本文分享的两种方法都可以帮助大家顺利解决问题。
