php - How do you use multiple controllers in CodeIgniter? -

i'm new codeigniter , i've gone through of user guide me understand how multiple controllers.

i have figured out how load multiple pages using 1 of examples. default controller, called site.php:

class site extends ci_controller {  public function index($page = 'home') {     if ( ! file_exists(apppath.'/views/'.$page.'.php')) {         // whoops, don't have page that!         show_404();     }      $data['title'] = ucfirst($page);      $this->load->view('header', $data);     $this->load->view($page, $data);     $this->load->view('footer', $data);      } } 

this works , routes.php:

$route['default_controller'] = 'site'; $route['(:any)'] = 'site/index/$1'; 

i have few views load correctly when go localhost/website/index.php/about, example.

---

now, further learn controllers , uri routing. created new controller, application/controllers/mycontroller.php , coded such:

class mycontroller extends ci_controller {     public function index() {         $this->load->view('header');         $this->load->view('my_controller');         $this->load->view('footer');     } } 

the thing is, don't know how access page. understand default uri pattern example.com/class/function/id/ have tried localhost/website/mycontroller , doesn't work. apache returns 404. i've tried many manipulations of this, going stupid typing localhost/website/index.php/mycontroller of course doesn't work.

what correct way use multiple controllers? have done wrong here? please assist me in learning, thank you!

_{(also, first proper question on stackoverflow, if i've done wrong or formatted incorrectly, please let me know!)}

the problem rule:

$route['(:any)'] = 'site/index/$1'; 

intercepts everything... , passes site controller, argument index method. if call:

/mycontroller 

it map to:

/site/index/mycontroller 

the routing happens before app looks @ controllers, , routing rules considered in order written.

thus need put rule @ bottom of rule list in order let other rules work. adding in front:

$route['mycontroller'] = 'mycontroller'; $route['(:any)'] = 'site/index/$1'; 

it should work fine (although sligthly unusual approach, global any rule) first check if url requested /mycontroller , if so, call mycontroller; otherwise behave used site controller.
