在CodeIgniter中扩展控制器类 [英] Extending The Controller Class in CodeIgniter

问题描述

我有类MY_Controller扩展CI_Controller 和大配置文件节的通用逻辑，所以I'va尝试创建 class Profile extends MY_Controller 具有公共逻辑的配置文件部分和所有类相关的这个部分应该扩展这个配置文件类，如我所知，但是当我试图创建 class Index profile Profile 我收到一个错误：

 致命错误：找不到类'Profile'
  / pre> 
 
 
 CodeIgniter尝试在我正在运行的 index.php 中找到这个类。 
 
 
 
我的错误在哪里？ 
解决方案
我认为你把你的MY_Controller放在/ application / core，并在配置中设置前缀。 
我会小心使用索引作为类名。作为Codeigniter中的一个函数/方法，它有一个专用的行为。
 
 
 
如果你想扩展该控制器，你需要把类放在同一个文件中。
 
 
 
例如In / application core 
  / * php文件的开头* / 
 class MY_Controller extends CI_Controller {
 public function __construct（）{
 parent :: __ construct（）; 
} 
 ... 
} 
 
 class another_controller extends MY_Controller {
 public function __construct（）{
 parent :: __ construct ; 
} 
 ... 
} 
 / * php文件结尾* / 
  
在/ application / controllers 
  class foo extends MY_Controller {
 public function __construct ）{
 parent :: __ construct（）; 
} 
 ... 
} 
  
或
  class bar extends another_controller {
 public function __construct（）{
 parent :: __ construct 
} 
 ... 
} 
  
 
I have class MY_Controller extends CI_Controller and common logic for big profile section, so I'va tried to create class Profile extends MY_Controller with common logic for profile section and all class related to this section should extends this Profile class as I understand right, but when I tried to create class Index extends Profile I recieve an error:
Fatal error: Class 'Profile' not found
CodeIgniter tries to find this class in index.php which I am running. 

Where is my mistake? Or maybe there is anoter better way to mark out common logic?
解决方案
I take it you have put your MY_Controller in /application/core, and set the prefix in the config.
I would be careful about using index as a class name though. As a function/method in Codeigniter it has a dedicated behaviour.

If you then want to extend that controller you need to put the classes in the same file.

E.g. In /application core
/* start of php file */
class MY_Controller extends CI_Controller {
    public function __construct() {
       parent::__construct();
    }
...
}

class another_controller extends MY_Controller {
    public function __construct() {
       parent::__construct();
    }
...
}
/* end of php file */
In /application/controllers
class foo extends MY_Controller {
    public function __construct() {
       parent::__construct();
    }
...
}
or
class bar extends another_controller {
    public function __construct() {
       parent::__construct();
    }
...
}
