Global variable in CI

[eluser]anishpsla[/eluser]
Is it possible to add global variable to CI ? For example, I want to use some parameter like site name to all page titles. Making it available all over the application will help.

There is more then one way you can do that. On my mind are two immediatelly:
1. save it in - application/constants.php
2. Declare variable in core/MY_Controller.php
Example

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends CI_Controller {

public $siteName = 'Name of Site';

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

/* End of file MY_Controller.php */
/* Location: ./application/core/MY_Controller.php */

Than in controller you need to extend MY_Controller, NOT CI_Controller:

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Some_controller extends MY_Controller {

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

        public function index()
        {
                echo $this->siteName;
        }

}

/* End of file some_controller.php */
/* Location: ./application/controllers/Some_controller.php */

Another way is with a config file, and then autoload it.

If you are setting application constants I'd recommend using a config file. In my app I auto-load /config/app.php that contains constants like the application name, support email, etc. Then you can access those variables using $this->config->item( 'name' ).

If they are true constants I'd add them to /config/constants.php and name them in all uppercase like the others.
