cake php link to the current page with different prefix

Question

In my default layout I would like to show link which points to the current page but with different prefix. I am using prefix 'language' to use address like www.site.com/eng/controller/action/param.

I tried $this->Html->link('eng', array('language' => 'eng') );

But this creates link with url eng/controller/action without passed arguments, without named arguments and without url params.

How I can do this? I would prefer elegant solution like 1 line of code - I know it can be done but can't find it :(.

Try this:

// helper method, possibly AppHelper, or in AppController and set a view var
function getCurrentParams() {
    $route = Router::currentRoute();
    $params = $this->request->params;
    $pass = $params['pass'];
    $named = $params['named'];
    unset($params['pass'], $params['named']);
    if (!empty($route->options['pass'])) {
        $pass = array();
    }
    return array_merge($params, $named, $pass);
}

$params = $this->SomeHelper->getCurrentParams();
$params['language'] = 'eng';
// use $params for your link now
