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

I provide my solution using the approach with

$request->headers->get('referer');

as suggested by gilden

/**
 * Your locale changing controller
 */
public function localeAction($locale)
{
    $request = $this->get('request');
    $router = $this->get('router');
    $context = $router->getContext();
    $frontControllerName = basename($_SERVER['SCRIPT_FILENAME']);

    if($request->hasSession())
    {
        $session = $request->getSession();
        $session->setLocale($locale);
        $context->setParameter('_locale', $locale);

        //reconstructs a routing path and gets a routing array called $route_params
        $url = $request->headers->get('referer');
        $urlElements = parse_url($url);
        $routePath = str_replace('/' . $frontControllerName, '', $urlElements['path']); //eliminates the front controller name from the url path
        $route_params = $router->match($routePath);

        // Get the route name
        $route = $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, '_locale' => true);
        $route_params = array_diff_key($route_params, $ignore_params);

        $url = $this->get('router')->generate($route, $route_params);

        return $this->redirect($url);
    }
}
