codeigniter钩子不能得到$ ci对象工作 [英] codeigniter hooks can't get $ci object to work

问题描述

我刚刚开始查看钩子今天不是100％肯定我做错了，但我得到一个错误，当我尝试和使用$ ci对象在我的函数。

I've just started looking at hooks today not 100% sure what I'm doing wrong but I'm getting an error when I try and use the $ci object in my function.

遇到PHP错误
严重性：注意
消息：尝试获取非对象的属性
文件名：hooks / language .php
行号：12

A PHP Error was encountered Severity: Notice Message: Trying to get property of non-object Filename: hooks/language.php Line Number: 12

我的hooks文件看起来像这样。它在我的应用程序文件夹的hooks目录中。

My hooks file looks like this. It's in the hooks directory in my application folder.

class Language{

    var $ci;

    public function __construct(){
       $this->ci =& get_instance();
    }

    function get_language(){
        echo $this->ci->session->userdata('language');
    }
}

我需要获取会话中的值才能使用在我的功能。我不应该这样做吗？

I need to get the value in the session to use in my function. Am I not supposed to do it like this?

感谢您！

推荐答案

在Base4 / 5.php文件中，get_instance（）函数被写入，它被有条件地加载，所以它不会存在，直到它被加载。这就是它给错误的原因。

In the Base4/5.php file the get_instance() function is written and it is conditionally loaded so it won’t be present until after it is loaded. And that's the reason its giving error.
