Multi language in laravel 11

In this article we will discuss localization in laravel.Multi Language is needed in almost every project here we will discuss all the basics that you need to know how we implement multi language in laravel 9,10 and 11.We will switch language based on user request and we will store that in session and then by using that session value in middleware we detect the language in laravel 8, laravel 9 laravel10 and laravel 11.

Create Language Files

Create a directory named `lang` and inside that lang folder create json files inwhich you want to localize.

// lang/en.json { "welcome": "welcome", "Elegant Laravel": "Elegant Laravel" } // lang/fr.json { "welcome": "bienvenu", "Elegant Laravel": "Laravel élégant" } // lang/it.json { "welcome": "benvenuto", "Elegant Laravel": "Elegante Laravel" }

            <h1>{{ __('Elegant Laravel') }}</h1>

    </div>
</body>
</html>

Route

Our route to change language in laravel.

Route::get('/lang',[LanguageController::class , 'change'])->name('user.lang');

Bussiness Logic Controller

input('lang');
        if (!in_array($lang, ['en', 'it', 'fr'])) {
            abort(400);
        }
        Session::put('locale', $lang);
        return redirect()->back();
    }
}

Set Up Middleware for Locale Switching

Now we will create a middleware that sets the locale based on user preference or request.

public function handle(Request $request, Closure $next): Response
{
    if ($request->session()->has('locale')) {
        App::setLocale($request->session()->get('locale', 'en'));
    }
    return $next($request);
}

withRouting(
        web: _DIR_ . '/../routes/web.php',
        commands: _DIR_ . '/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->web(append: [
            SetLocale::class,
        ]);
    })
    ->withExceptions(function (Exceptions $exceptions) {
        //
    })->create();
