How to use localization in laravel multilanguage support

In this article let’s understand How to use localization in laravel multilanguage support. Let’s understand through steps:

  • Create language files
  • Create and configure middleware
  • Create route – controller – view
  • Add translations to lang files
  • Result

Step 1 : Create local files

First of all lets create language files at resources/lang/{en.json, fr.json}. Checkout below structure.


Configure and check locale at “config/app.php”

'locale' => 'en',
'fallback_locale' => 'en',
  • The application locale determines the default locale that will be used by the translation service provider.
  • The fall-back locale determines the locale to use when the current one is not available.

Step 2 : Create middleware

We need to apply this middleware to filter out routes that will use localization functionality we will create. Create one at app/Http/Middleware/Localization.php as below:

  • Basically this middleware will set the value from session. So we will update the session value while switching the language and it will take care of the rest.
namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
use Illuminate\Support\Facades\Session;

class Localization
    public function handle(Request $request, Closure $next)
        if (Session::has('locale')) {
        return $next($request);

We will add the middleware in our kernal file to apply this to each and every request. Add as below at app\Http\Kernel.php

 protected $middlewareGroups = [
        'web' => [


Step 3 : Create route – controller – view

Lets create two routes first at \routes\web.php as below:

Route::get('locale', [LocaleController::class, 'view'])->name('locale');
Route::get('change-locale', [LocaleController::class, 'changeLocale'])->name('changeLocale');
  • locale‘ – We will use for our main view
  • change-locale’ – We will use to switch the language

Lets create our controller now at app\Http\Controllers\LocaleController.php as below:

namespace App\Http\Controllers;
use Illuminate\Http\Request;

class LocaleController extends Controller
    public function view()
        return view('locale');
    public function changeLocale(Request $request)
        $validated = $request->validate([
            'locale' => 'required',
        \Session::put('locale', $request->locale);
        return redirect()->back();
  • view() – We are simply loading a view from blade file.
  • changeLocale() – Using it to get the requested language and update session.

Next, let’s create our view file as below at laravel\resources\views\locale.blade.php

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">


        <!-- Fonts -->
        <link rel="preconnect" href="">
        <link href=",600&display=swap" rel="stylesheet" />
        <script src=""></script>
        <!-- Styles -->
          * {
                box-sizing: border-box;
                body {
                font-family: Arial, Helvetica, sans-serif;
                header {
                background-color: #666;
                padding: 30px;
                text-align: center;
                font-size: 35px;
                color: white;
                article {
                background-color: #f1f1f1;
                height: 300px;
                footer {
                background-color: #777;
                padding: 10px;
                text-align: center;
                color: white;
            <h2>{{ __('welcome_home')}}</h2>
            <select class="form-select p-3" name="locale" style="width: 10%;">
                <option value="en" {{ Lang::locale() == 'en' ? 'selected' : '' }}>English</option>
                <option value="fr" {{ Lang::locale() == 'fr' ? 'selected' : '' }}>French</option>
                <h3 style="margin:0">{{ __('welcome_home')}}</h3>
                <p>{{ __('text')}}</p>
            <p>{{ __('thank_you')}}</p>
        <script type="text/javascript">
            $(document).ready(function() {
                $('select[name=locale]').change(function() {
                    window.location.href = "{{ route('changeLocale') }}?locale="+ $(this).val();
  • Create few html blocks that represents translation
  • Will use select dropdown to switch between languages
  • Set javascript to call route on change event of language
  • Use syntax {{ __(‘text’)}} where text will represent the key from json file.

Step 4 : Add translations to lang files


    "welcome_home":"Welcome Home",
    "text":"Home, a word that holds immense significance and embodies a sense of belonging, comfort, and love. It is a place where we can truly be ourselves, where our joys and sorrows are shared, and where lasting memories are created.",
    "thank_you":"Thank you"


    "welcome_home":"Bienvenue à la maison",
    "text":"Accueil, un mot qui a une immense signification et incarne un sentiment d'appartenance, de confort et d'amour. C'est un endroit où nous pouvons vraiment être nous-mêmes, où nos joies et nos peines sont partagées et où des souvenirs durables sont créés.",

Step 5 : Result

Head to route “http://localhost:8000/locale” and check result

Switch the language from header and see result:
