Symfony2: Backward Uri (Referrer) during switching locale

Question

I\'d like to implement locale switcher, but it seems with no luck...

The code below doesn\'t work because the (Referrer) contains the old value of locale...

Answer 1

Gilden, thanks a lot for idea, but it's doesn't work anyway...

Here is the controller LOCALE SWITCHER:

class LocaleController extends Controller
{
public function changeAction($locale, Request $request)
{
    if ($request->hasSession())
    {
        $session = $request->getSession();
        $session->setLocale($locale);

        $route_params = $session->get('jet_referrer');
        $route_name = $route_params['_route'];

        // Some parameters are not required to be used, filter them
        // by using an array of ignored elements.
        $ignore_params = array('_route' => true, '_controller' => true,
                               '_template_default_vars' => true);
        $route_params = array_diff_key($route_params, $ignore_params);

        $url = $this->get('router')->generate($route_name, $route_params);
        return $this->redirect($url);
    }
}
}

Here is the controller of BUSINESS LOGIC:

/**
 * @Route("/{_locale}")
 */
class TestController extends Controller
{
/**
 * @Route("/", name="_test")
 * @Template()
 */
public function indexAction(Request $request)
{
    $request->getSession()->set('jet_referrer', $request->attributes->all());
    return array();
}

/**
 * @Route("/hello/{name}", name="_test_hello")
 * @Template()
 */
public function helloAction($name, Request $request)
{
    $request->getSession()->set('jet_referrer', $request->attributes->all());
    return array('name' => $name);
}
}

Regarding IGNORED params for array_key_diff()...

_controller
_locale
_route
_template
_template_default_vars
_template_vars

I've tried to include few of them for the new route generation, but with no luck... Don't understand what is going on...

It's seems just a hack... Do we have more sofisticated way to realize this simple feature in Symfony2 ?? RAW PHP allows me to do that much & much more easily...

Thanks again.
