钩在Codeigniter

问题描述

我怎么只为CodeIgniter中的几个控制器而不是所有控制器调用一个钩子？

How can I call a hook for only a few controllers instead of all controllers in CodeIgniter?

例如：我只想为admin部分运行该钩子。我该如何实现？

E.g.: I want to run the hook for only the admin section. How can I achieve this?

推荐答案

在希望有选择地运行的钩子中，可以使用<$访问ci超级对象。 c $ c> $ this-> ci =& get_instance（）; 。这充当指针，可用于访问CodeIgniter路由器，以使用 $ class = $ this-> ci-> router-> fetch_class（）; 。然后，您可以检查 $ class 是否匹配某个值。这会给你：

In the hook which you wish to run selectively, you can access the ci superobject using $this->ci =& get_instance();. This acts as a pointer which can be used to access the CodeIgniter router to determine the class using $class = $this->ci->router->fetch_class();. You can then check if $class matches a certain value. This would give you:

<?php class Post_controller_constructor {
    var $ci;

    function __construct() {

    }

    function index()
    {
        $this->ci =& get_instance();
        $class = $this->ci->router->fetch_class();
        if($class === 'admin') {
            // Hook procedures
        }
    }
}

/* End of file post_controller_constructor.php */
/* Location: ./application/hooks/post_controller_constructor.php */
