Codeigniter 扩展扩展 MY_Controller [英] Codeigniter extending extended MY_Controller

问题描述

我严格遵循了操作方法Phil Sturgeon 撰写的文章，用于扩展基本控制器.但我仍然遇到一些错误.

我的 3 节课:

//application/libraries/MY_Controller.php类 MY_Controller 扩展控制器{公共函数 __construct(){parent::__construct();}}//应用程序/库/Public_Controller.php类 Public_Controller 扩展 MY_Controller{公共函数 __construct(){parent::__construct();}}//应用程序/控制器/user.php类用户扩展 Public_Controller{公共函数 __construct(){parent::__construct();}}

<块引用>

致命错误:在第 2 行的/srv/www/xxx/application/controllers/user.php 中找不到Public_Controller"类

好奇的是，如果我直接从 MY_Controller 扩展，下面的代码片段是有效的:

//application/controllers/user.php类用户扩展 MY_Controller{公共函数 __construct(){parent::__construct();}}

我已经通过 __autoload() 或手动加载了控制器.控制器加载成功.

CI 版本:1.7.3

解决方案

你需要在你的 MY_Controller 中 require Public Controller

//application/libraries/MY_Controller.php类 MY_Controller 扩展控制器{公共函数 __construct(){parent::__construct();}}需要(APPPATH.'libraries/Public_Controller.php')；

您收到错误是因为 Public_Controller 从未加载过.这样做将允许您从 Public_Controller

扩展

我喜欢你正在做的事情，因为我一直都在这样做.

当您想创建 Admin_Controller 时，您也可以在 MY_Controller 中执行此操作

//application/libraries/MY_Controller.php类 MY_Controller 扩展控制器{公共函数 __construct(){parent::__construct();}}需要(APPPATH.'libraries/Public_Controller.php')；//包含一些仅适用于 `public` 控制器的逻辑需要(APPPATH.'libraries/Admin_Controller.php')；//包含一些仅适用于 `admin` 控制器的逻辑

I have strictly followed the how-to article by Phil Sturgeon, to extend the base controller. But I get still some errors.

My 3 classes:

// application/libraries/MY_Controller.php
class MY_Controller extends Controller{
    public function __construct(){
        parent::__construct();
    }
}

// application/libraries/Public_Controller.php
class Public_Controller extends MY_Controller{
    public function __construct(){
        parent::__construct();

    }    
}

// application/controllers/user.php
class User extends Public_Controller{
    public function __construct(){
        parent::__construct();
    }
}

Fatal error: Class 'Public_Controller' not found in /srv/www/xxx/application/controllers/user.php on line 2

Curious is that the following snippet is working, if I directly extends from MY_Controller:

// application/controllers/user.php
class User extends MY_Controller{
    public function __construct(){
        parent::__construct();
    }
}

I have loaded the controllers via __autoload() or manually. The controllers are loaded succesfully.

解决方案

You need to require the Public Controller in your MY_Controller

// application/libraries/MY_Controller.php
class MY_Controller extends Controller{
    public function __construct(){
        parent::__construct();
    }
}

require(APPPATH.'libraries/Public_Controller.php');

You get the error because Public_Controller was never loaded. Doing this would allow you to extend from Public_Controller

I like what you are doing because I do that all the time.

You can do this also in your MY_Controller when you want to create an Admin_Controller

// application/libraries/MY_Controller.php
class MY_Controller extends Controller{
    public function __construct(){
        parent::__construct();
    }
}

require(APPPATH.'libraries/Public_Controller.php'); // contains some logic applicable only to `public` controllers
require(APPPATH.'libraries/Admin_Controller.php'); // contains some logic applicable only to `admin` controllers
