问题


i’m using the Codeigniter.2.1.3 for a website, so i need to extend the CI_Controller so i can add a method to be executed with all controllers so i did what’s in the user_guide:

creating a file named MY_Controller.php in the application/core folder the creating in it MY_Controller Class that extends the CI_Controller, the changing my regular controller to extend the MY_controller like this: MY_controller.php:

class MY_Controller extends CI_Controller{
    protected $page;
    # Constructor
    function __construct (){
        parent::__construct();
        #code shared with all controllers
    }
    public function get_page(){
        #code to get_the right page here
    }
}

regular controller named Regular.php:

class Regular extends MY_Controller{
     public function __construct(){
         parent::__construct();
     }
     public function index(){
          $this->get_page();
     }
}

but the following error keep appearing:

Fatal error: Class ‘MY_Controller’ not found in /var/www/immo/CodeIgniter_2.1.3/application/controllers/regular.php on line 2


回答1:


You would need to include your MY_Controller class or auto-load it. I suggest you auto-load it by adding the following to your application/config/config.php file.

function __autoload($class)
{
    if (strpos($class, 'CI_') !== 0)
    {
        if (file_exists($file = APPPATH . 'core/' . $class . EXT))
        {
            include $file;
        }
    }
} 



回答2:


Make sure the filename is perfectly cased. Linux server is case-sensitive. So if the class name is My_Controller then the name of the file should be My_Controller.php




回答3:


$config['subclass_prefix'] = "MY_"

check that in config.php and of course you should use it in Controller Name Like MY_Controller.php and Named "class MY_Controller...."




回答4:


Late with this answer, but I got the "Fatal error: Class ‘MY_Controller’ not found" error when I had a controller (php) file by the same name at the web root instead of the application/controllers directory. Don't know how it got there, actually, but the problem went away when I deleted it.

in config/config.php

/* load class in core folder */
function my_load($class) {        

    if (strpos($class, 'CI_') !== 0) {            
        if (is_readable(APPPATH . 'core' . DIRECTORY_SEPARATOR . $class . '.php' )) {                
            require_once (APPPATH . 'core' . DIRECTORY_SEPARATOR . $class . '.php');                
        }
    }

}

spl_autoload_register('my_load');
