A language switcher in Symfony 2.4

Question

I have an object Language, and I can add, delete and update languages from the admin page.

What I want to do, is to add a language switcher, I put this html/twig code:

 {% for language in languages %}         
      <li><a href="{{ path('evr_footer_switch_language',{'locale': language.code | lower }) }}">{{ language.language | capitalize }} ({{ language.code }})</a></li>
 {% endfor %}

And an action the route for the action is evr_footer_switch_language, the one I used in the switcher above:

 public function switchlanguageAction($locale = 'en') {

        $this->get('session')->set('_locale', $locale);
        $request = $this->getRequest();
       $request->setLocale($locale);
        return $this->redirect($request->headers->get('referer'));
    }

This is the route I defined for the action/controller switchlanguageAction()

evr_footer_switch_language:
    pattern: /language/switch/{locale}
    defaults: { _controller: EvrHomeBundle:Footer:switchlanguage, locale: en }

It seems to me very simple in principle, you click on the link of the language (got from the database), send the code of the language (exemple : 'fr', 'en', 'zh' etc...) to the action as a $locale variable, then set the Locale of the session/request to this value.

The problem is that none of this works, and the language is still 'EN' (default value).

Note According to the requirements of this project, The language can't be mentioned in the URL (like fr/articles, en/articles), but the same URL (/articles/) can show in different languages, this is why I didn't use the pre-defined slug (_locale).

Thanks

While in search for some more details in order to write an answer I stumbled upon this Symfony cookbook entry: Making the Locale "Sticky" during a User's Session

I think that's exactly what you need ;)

Thanks so much for your answer +1, but ...I created a listener, and Added it to the services.yml (the same steps described in the article you mentioned), then I set the locale from the controller, but in vain...it didn't work yet. – SmootQ Feb 07 '14 at 11:57
Thank you so much again , I applied what the doc says, But to set the locale I used only `$request->setLocale()`, and now I added the `$this->get('session')->set('_locale')`, it works ... Best answer ! – SmootQ Feb 07 '14 at 12:02

Symfony 2.6: I used the LocaleListener mentioned in "Making the Locale Sticky", but also had to use this to get things working properly:

/** from Controller
 *
 * @Route("/changeLanguage/{changeToLocale}", name="changeLanguage")
 *
 */
public function changeLanguageAction($changeToLocale){
    $this->get('request')->attributes->set('_locale', null);
    $this->get('session')->set('_locale', $changeToLocale);

    return $this->redirect($this->generateUrl('index'));
}

public function onKernelRequest(GetResponseEvent $event)
{
    $request = $event->getRequest();
    if (!$request->hasPreviousSession()) {
        return;
    }

    // try to see if the locale has been set as a _locale routing parameter
    if ($locale = $request->query->get('swich_language')) {

        $request->getSession()->set('_locale', $locale);
        $routing = $this->router->match($request->getPathInfo());

        $route_params = array();

        foreach ($routing as $key => $value) {
            if($key[0] !== "_")
            {
                $route_params[$key] = $value;
            }
        }

        $parameters = \array_merge($route_params, array("_locale" => $locale));
        $url = $this->urlGenerator->generate($routing['_route'], $parameters);

        $response = new RedirectResponse($url);
        $event->setResponse($response);
    }
}

You can add as a kernel request and with querystring swich_language you can change it

Thank you so much for your answer +1 , in fact the question is 4 years old, but it is still useful to have many solutions, thank you. <3 — SmootQ, Nov 19 '18 at 08:39
