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

Answer 1

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

'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')
