CodeIgniter：Hooks（pre_controller）加载助手

问题描述

我正在尝试在我的pre_controller钩子中加载cookie助手，用于我们网站上的记住我功能。我认为创建CI对象的实例$ ci =& get_instance（）;

I am trying to load the cookie helper in my pre_controller hook for a 'remember me' function on our site. I thought that creating an instance of the CI object with $ci =& get_instance(); would allow me to access to loading helpers but this is not the case.

想法？

 $ci =& get_instance();
 $ci->load->helper('cookie');
 // does not load

推荐答案

code> pre_controller 钩子在超级对象完全构造之前执行，因此 get_instance（）无法工作 - 静态对象

The pre_controller hook executes before the super object has been fully constructed, so get_instance() can't work - the static object it returns a reference to hasn't yet been initialized.

请考虑使用 post_controller_constructor 钩子;您的控制器的构造函数将已执行，并且CI超级对象将可供使用。

Consider using the post_controller_constructor hook instead; your controller's constructor will have executed, and the CI super object will be available for use.
