每次在 CodeIgniter 中加载页面时运行一个函数

我以前只在 Asp.Net MVC 中制作过 Web 应用程序，您可以在 BaseController 上设置的“ActionFilter”中使用 OnResultExecuted 来在每次执行操作方法时运行一个方法（即基本上每次有人访问该中的任何页面时）应用）。

我如何在 CodeIgniter/PHP 中做同样的事情？

编辑：

我根据建议之一尝试使用 post_controller_constructor ，但这没有帮助：

$hook['post_controller_constructor'] = array(
                                'class'    => 'PreController',
                                'function' => 'getIp',
                                'filename' => 'preController.php',
                                'filepath' => 'hooks'
                                );

我仍然得到 Undefined property: PreController::$input （我只是没有重命名所调用的类，如果目前仍称为 PreController）。

但事实仍然是我无权访问输入属性...显然我无权访问输入类，那么我该怎么做呢？我相信如果我在控制器中做了同样的事情那就没问题了，但是从钩子中呢？我该怎么做？

I have previously only made web applications in Asp.Net MVC, and there you can use OnResultExecuted in an "ActionFilter" set on the BaseController to run a method each time an action method is executed (i.e. basically each time anyone visits any page in the application).

How would I do the same thing in CodeIgniter/PHP?

EDIT:

I tried using post_controller_constructor instead, according to one of the suggestions, but that doesn't help:

$hook['post_controller_constructor'] = array(
                                'class'    => 'PreController',
                                'function' => 'getIp',
                                'filename' => 'preController.php',
                                'filepath' => 'hooks'
                                );

I still get Undefined property: PreController::$input (I just haven't renamed the class called, that shouldn't matter if it is still called PreController for the moment).

But the fact remains I do not have access to the input property... Obviously I don't have access to the Input Class, so how do I do that? I belive if I had done the same thing in a Controller it would have been ok, but from a hook? How do I do this?

您可以使用 CodeIgniter 挂钩： http://www.codeigniter.com/user_guide/general /hooks.html

您可以挂钩几个“事件”，请查看文档页面的底部。

回应评论：

重新阅读您的评论并编辑...似乎您假设您的钩子类是当前控制器 - 但事实并非如此。当前控制器是与 URI/路由映射匹配的任何控制器（例如，site.com/users/view/1 将使用 Users 控制器，而不是您的钩子处理程序PreController 类）。挂钩处理程序可以是一个不继承自 CI_Controller 的简单 PHP 类。

在钩子处理程序中您需要做的第一件事是获取实际控制器，其中将包含输入引用和其他内容。

class HookHandler {
    function post_controller_constructor() {
        $ci =& get_instance();
        // ... now you can use $ci->input and other controller members
    }
}

You can use CodeIgniter hooks for that: http://www.codeigniter.com/user_guide/general/hooks.html

There are several "events" you can hook into, check the bottom of the documentation page.

In response to the comment:

Re-read your comment and edit... it seems that you're assuming that your hook class is the current controller -- it isn't. The current controller is whatever matches the URI/route mapping (for example, site.com/users/view/1 would be using the Users controller, and not your hook handler PreController class). The hook handler can be a simple PHP class not inheriting from CI_Controller.

The first thing you need to do in the hook handler is to get hold of the actual controller, that will contain the Input reference and others.

class HookHandler {
    function post_controller_constructor() {
        $ci =& get_instance();
        // ... now you can use $ci->input and other controller members
    }
}
