CakePHP Index with query

Question

I'm building a prototype search application using CakePHP and I have a search controller that has the following code so far:

class SearchController extends AppController
{
    var $name = 'Search';

    var $uses = array();

    function index ( $query )
    {
        $query = $_GET['q'];

        $this->set('title_for_layout', $query. ' &ndash; smplr');

        // if no query then redirect to home
        if ( !$query )
        {
            $this->redirect(array('controller' => 'home', 'action' => 'index'));
        }
    }
}

So this would be fired when a user has something like this: domain.com/search?q=Hello

My question is how to use the query passed into index() ?

At the moment I have to manually create a new variable to grab the query string using $_GET which I'm sure is NOT the way to do this using Cake.

Any help much appreciated. Thanks

You need to use:

$this->params['url']['q'];

More specifically:

function index ( $query )
    {
        $query = $this->params['url']['q'];

....

So I wouldn't need the $query inside the index() at all then? As I could just use the variable content straight from the params?

Yes, you wouldn't need to catch $query as a function argument.

Why not though? When dealing with normal functions like creating, editing etc you would do. Thanks

Because you're not passing it the normal way. Your url is: domain.com/search?q=asdf. To catch it how you want to, your url should be: domain.com/search/index/asdf

What's the difference between $query = $this->params['url']['q']; and $query = $_GET['q'];
