query database in all pages

[eluser]keithics[/eluser]
Hello Guys,

I have a website which has a header in all pages. This header has to query (using a model) from a database like getting all the product categories and display it as a drop down (in the header).

The question is.. how can I get the categories without having to put $this->posts_model->get_cat() in all functions and classes?

note: model is autoloaded.

Add in youre constructor what you need.

Code:

function __construct() {
        parent::Controller();
        $data['dropdown'] = $this->posts_model->get_cat();        
    }

function index()
{

  $this->load->view('youreview', $data);

}

function Other()
{
  $this->load->view('other', $data);
}
