我应该扩展控制器还是创建助手？ [英] Should I extend Controller or Create Helper?

问题描述

我需要访问CodeIgniter应用程序中多个控制器中的某些功能。目前，这些功能实际上是基本功能，例如：

I need to access some functions in multiple controllers in a CodeIgniter application. At the moments the functions are really basic and a few, For example:

        generate_random_key()  //just a random string
        is_logged()           //check if user is logged or not
        logged_user_only()    //if unlogged, redirect
        unlogged_user_only() //if logged, redirect

由于这些功能与登录相关，因此我可以将它们放在帮助程序文件中，然后放置在 Application / helpers / login_helper中.php

As these functions are related to login, I can either put them in a helper file and place in Application/helpers/login_helper.php

OR

我可以扩展CI_Controller，方法是创建 MY_Controller.php 并将其放在 Application / Core / MY_Controller.php

i can extend the CI_Controller, by creating MY_Controller.php and put it in Application/Core/MY_Controller.php

这两种方法均有效，但我想知道哪种方法更适合此类任务。我认为应该有一些规则，何时扩展Controller或何时使用辅助程序？

Both of the methods work, but I am wondering which one fits better for this kind of task. I think there should be some rules, when the Controller should be extended or when the helper should be used?

推荐答案

在其他控制器中（并且仅在其他控制器中）重新使用这些函数，我建议将它们重构为MY_Controller。
这也使您可以直接访问$ CI实例（而不是调用get_instance（））

If you're using these functions in your other controllers (and only in your other controllers) I would suggest refactoring them into MY_Controller. This would also give you direct access to the $CI instance (instead of calling get_instance())

另一方面，您可以创建一个身份验证库。

On the other hand, you could create an Authentication library. This might be more suitable..

编辑：

我建议使用MY_Controller作为基础，包含身份验证包装函数，可从管理此类内容的库中调用功能。

I would recommend having a MY_Controller as a base, that contains auth wrapper functions, which invoke functionality from a Library that manages this type of thing.
