Laravel 5.8 setLocale globally

Question

I have a route:

    Route::get(\'/setlocale/{locale}\', function($locale) {
            App::setLocale($locale);

            


        

Answer 1

Try this way

1. firstly when user choose a language we put our selected locale(language) in session [example en, fr, hi ]

Route::get('setlocale/{locale}',function($lang){
       \Session::put('locale',$lang);
       return redirect()->back();   
});

2. Second We use a middleware for translating pages according to our session locale (user selected)

3. Third we put this middleware in kernel.php routeMiddleware (app/Http/kernel.php)

protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'language' => \App\Http\Middleware\LanguageSwitcher::class,        
    ];

'language' => \App\Http\Middleware\LanguageSwitcher::class,

4. Fourth, serving this middleware we need route group. so each request goes through this middleware

Route::group(['middleware'=>'language'],function ()
{
    //your translation routes
});

Logic in middleware

In middleware for every request we check if locale set in current session or not. if Session not having locale then for current request we set locale to config locale means in your app configuration locale

'locale' => 'en',  // config/app.php
 Session::put('locale',Config::get('app.locale')); // in middleware code we use Config method to get app configuration locale
App::setLocale(session('locale')); // finally set this to App locale

else if we have locale in current session then we set that to App locale

App::setLocale(session('locale')); // set this to App locale
