As the project progresses, you ’ ll spend more and more time in the controller, loading models, using
libraries, and loading views as appropriate.

Before creating your views, you will need to do a bit of work on the index() function. Although you
haven ’ t created any views, you already have some design considerations in mind:

1. You need to load the navigation.


2. You need to load a template and reuse that template as often as possible.


3. At some point, you ’ ll need to consider the use of subtemplates that are included in the master
   template.

You can ’ t do anything about the third point at the moment, but you can do something about the other
two. Create your index() function controller like this:

function index(){

$data[‘title’] = “Welcome to Claudia’s Kids”;

$data[‘navlist’] = $this- > MCats- > getAllCategories();

$this- > load- > vars($data);

$this- > load- > view(‘template’);

}

Here ’ s what will happen when you visit the home page of your site:

$data[ ’ title’] will be used as $title in the template view.

The categories from the database are retrieved into $data[‘navlist’] by the MCats model,

and then passed along to the underlying view.

The footer, header, and navigation subviews don ’ t need to be loaded here, as they ’ ll be loaded

inside the template.php view.
