Data available for all views in codeigniter

Question

I have a variable, contaning data that should be present in the entire site. Instead of passing this data to each view of each controller, I was wondering if there is a way to make this data available for every view in the site.

Pd. Storing this data as a session variable / ci session cookie is not an option.

Thanks so much.

Answer 1

Create a MY_Controller.php file and save it inside the application/core folder. In it, something like:

class MY_Controller extends CI_Controller {

   public $site_data;

   function __construct() {
       parent::__construct();
       $this->site_data = array('key' => 'value');
   }
}

Throughout your controllers, views, $this->site_datais now available. Note that for this to work, all your other controllers need to extend MY_Controllerinstead of CI_Controller.

Answer 2

You need to extend CI_Controller to create a Base Controller:

https://www.codeigniter.com/user_guide/general/core_classes.html

core/MY_Controller.php

<?php

class MY_Controller extend CI_Controller {

     public function __construct() {
         parent::__construct();

         //get your data
         $global_data = array('some_var'=>'some_data');

         //Send the data into the current view
         //http://ellislab.com/codeigniter/user-guide/libraries/loader.html
         $this->load->vars($global_data);

     }  
}

controllers/welcome.php

 class Welcome extend MY_Controller {
      public function index() {
          $this->load->view('welcome');
      }
 }

views/welcome.php

var_dump($some_var);

Note: to get this vars in your functions or controllers, you can use $this->load->get_var('some_var')
