$Variable available in all controllers

[eluser]hugle[/eluser]
Hello Everyone.

I want to call :

Code:

$this->load->helper('date');
$datestring = "%l, %j %F, %G:%i";
$this->data['nav_time'] = mdate($datestring, time());

in every of of controller, so I have $this->data['nav_time'] value in every controller.
I understood that I need to use a hook in pre_controller probably?

But can't understand really how is it done ...
I have looked into howto - but no good result

Anyone can point me on this?
Thank you!

You could extend the controller class. Maybe this may work:

Code:

class MY_Controller extends Controller {

    var data;

    function My_Controller()
    {
        parent::Controller();
        $this->load->helper('date');
        $datestring = "%l, %j %F, %G:%i";
        $this->data['nav_time'] = mdate($datestring, time());
    }
}

And in your controllers you now have to extend MY_Controller instead of Controller class and in every one of your controllers the $this->data variable should be available.

why not autoload a custom config file with

Code:

$config['nav_time'] = date('l, j F, G:i');

Or add following to the constants.php file

Code:

define('NAV_TIME', date('l, j F, G:i'));

The mdate function is only useful if you have text inside the dateformat, take a look at the example in the user guide.
