Change locale language in run time

Because you're not persisting it, only changing it for the current request.

You could have the LanguageController set a session variable, and use that within a ServiceProvider to actually set the language.

So in your LanguageController, where you now have something like:

app('translator')->setLocale($locale);

You would replace it with:

\Session::put('locale' , $locale);

and in your app\Providers\AppServiceProvider.php:

    public function register()
    {
        // grab locale from session, or use the default....
        $locale = \Session::get('locale',  \Config::get('app.locale'));
        app('translator')->setLocale( $locale  );
    }

Hi @lostdreamer_nl, thanks for answered. So, I alredy tried to save a variable in session but it doesn't persist either. I've alredy enabled session in my config file and then tried to use app('session')->get('locale') and it returns empty.

What version of Lumen are you using (I just noticed that Lumen >= 5.2 has no session support anymore)?

If you're using < 5.2

Did you also set it up in your bootstrap.php? https://lumen.laravel.com/docs/5.1/session and with which configuration

If it's >= 5.2 you're using, you should probably install the session provider first.

I'm using Lumen 5.5, I've alredy installed illuminate/session package and made the configurations to enable but I still with this problem.
