Check if controller exist

Hello everyone...
I wander,
Is there any way that i can check if controller exist and if not then go to another controller?

As far as I know you can only check for classes (that's what controller are)
that are loaded.
What you can do is set up rules in config/routes.php that point to somewhere in case
a controller is called that don't exist.

ok...

1. where in the config file i can do this?


2. maybe if i tell you what i'm trying to do you can give another way to do it.

I try to built a small cms with an option for the admin to create a new page.
the page that he will create will be save in the view folder.

what i think about is to build a controller which will display the page without creating a new controller.

this is the controller:

Code:

<?php
class Pages extends Controller{
    
    function index($page){
        
        $data['main_content'] = $page;
        $this->load->view('includes/template', $data);
        
    }
}

and i get the $page from the address bar.

is there any other way to do so?

I assume that $page is the name of the view_file that should be loaded?
In that case you can check with the php function

Code:

file_exists()

Have a look here:
http://php.net/manual/de/function.file-exists.php

Check if the view file can be found in your view directory and if not
let the page display an existing one that makes sense for you.

Most common CMS will store page data in the database. Here is how I am doing this same thing

Code:

class Pages extends CI_Controller{

   public function __construct(){
      parent::__construct();
      $this->load->model('pages_model');
   }
    
    function index($page = 'home'){
        
        //Get page from DB
        $data['main_content'] = $this->pages_model->get_page($page);
        
        if($data['main_content'] == FALSE){
            //Display not found page
            $data['main_content'] = $this->load->view('page_not_found', $data, TRUE);  //Save the contents of the view
        }    

        $this->load->view('includes/template', $data);
        
    }
}

//In routes.php
$route['pages/(:any)'] = 'pages/index/$1';
$route['pages']        = 'pages/index/home'; //Load home page if no segment is passed

Now using these routes your links would be pages/home, pages/about_us, pages/services etc.
