Silex : allow user to change langage by clicking on html element and keeping clean URL

Question

I am using Silex and Twig for a website and I want to allow the user to change the langage of the site.

My problem

Right now, it works if I change the loca

Answer 1

I finally find a solution to do what I want, using pmaxs/silex-locale (https://github.com/pmaxs/silex-locale).

As I said in my question, I already used it for my translation but I didn't used the "Url generation" as I should...So here is a recap of how to use it (read the documentation if you use Silex v1.x):

1/ Loading Provider

$app->register(new \Pmaxs\Silex\Locale\Provider\LocaleServiceProvider(), [
    'locale.locales' => ['en', 'fr'],  //I want to translate my site in English and French
    'locale.default_locale' => 'en',   // By default, the locale is "en"
    'locale.resolve_by_host' => false,
    'locale.exclude_routes' => ['^_']
]);
$app->register(new Silex\Provider\LocaleServiceProvider());

2/ Usage

Here is my home route controller :

// this page is accessible by urls '/', '/fr/' or '/en/'
$app->match('/', function (Request $request) use ($app) {

    // my code

     return $app['twig']->render('home.html.twig');
})->bind('home');

As you can see, I have no {_locale} variable in my routing, but still can use it to change the langage of my page.

3/ Url generator

Now, here is how I change my langage :

{% set locale_list = ["en", "fr"] %} // the list of all langage in my website
{% set current_locale = global.request.getLocale() %} // the current langage of my page


    // I display the current langage
    {{ current_locale|upper }} 
    

        

            {% for locale in locale_list %}
                {% if locale != current_locale %}
                    // I create one link to change the langage according to all the langage I want, minus the current langage
                    
                        {{ locale|upper }}
                    
                 {% endif %}
             {% endfor %}
         
     
 

I'm using the "Url Generator", it works like this : locale_generate('es', $name, $parameters = array(), $referenceType = UrlGeneratorInterface::ABSOLUTE_PATH) (more details in the documentation).

This way, when I come in my website I'm in english (my default locale) with my "clean Url" /. Then by clicking on FR my url become /fr/ and my content is translate in French with a new selection menu (current-langue = FR and I can select "EN").
