This tutorial explains how to create a language system and be able to change the language in the menu with the corresponding translations.
I will try to be clear and concise 😃
Check out a Spanish translation here
Setup
First, you need to create a controller App/Http/Controllers to record the language in session and be able to retrieve it with the middleware we will create just after :
namespace App\Http\Controllers;
use App;
use Illuminate\Http\RedirectResponse;
class LocalizationController extends Controller
{
/**
* @param $locale
* @return RedirectResponse
*/
public function index($locale)
{
App::setLocale($locale);
session()->put('locale', $locale);
return redirect()->back();
}
}
Now, you must create a middleware App/Http/Middleware to retrieve the language that was recorded in session :
namespace App\Http\Middleware;
use App;
use Closure;
class Localization
{
/**
* Handle an incoming request.
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if (session()->has('locale')) {
App::setLocale(session()->get('locale'));
}
return $next($request);
}
}
After that, you must save the middleware in app/http/Kernel.php :
/**
* The application's route middleware groups.
* @var array
*/
protected $middlewareGroups = [
'web' => [
(...)
\App\Http\Middleware\Localization::class,
],
(...)
];
Finaly, create a route to change the language :
use App\Http\Controllers\LocalizationController;
Route::get('lang/{locale}', [App\Http\Controllers\LocalizationController::class, 'index']);
Create the dropdown
First, you must create a flag folder in public/images and store flags images inside :
Secondly, in your menu, insert this code to be able to switch from one language to another :
@php $locale = session()->get('locale'); @endphp
<li class="nav-item dropdown">
<a id="navbarDropdown" class="nav-link dropdown-toggle" href="#" role="button"
data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" v-pre>
@switch($locale)
@case('en')
<img src="{{asset('images/flag/en.png')}}" width="25px"> English
@break
@case('fr')
<img src="{{asset('images/flag/fr.png')}}" width="25px"> Français
@break
@default
<img src="{{asset('images/flag/en.png')}}" width="25px"> English
@endswitch
<span class="caret"></span>
</a>
<div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="lang/en"><img src="{{asset('images/flag/en.png')}}" width="25px"> English</a>
<a class="dropdown-item" href="lang/fr"><img src="{{asset('images/flag/fr.png')}}" width="25px"> Français</a>
</div>
</li>
Let's try it
To test that everything works, insert this code on your homepage or any other page :
<h1>@lang("Bonjour")</h1>
Then to finish, in the resources/lang folder, you have to create a folder for each language you want (for example fr and en) and for each folder, do the following to take into account the text of the homepage to translate :
<?php
// EN folder
return [
'Bonjour' => 'Hello'
];
Here we go, now if you click on the english flag in your menu, the Bonjour text will change to Hello.
Notice that if you need, there is another way to make translations using json :
{
"Bonjour" : "Hello"
}

I found the error, and fixed it. You need to begin with a forward slash both in your route and your menu... so
Route::get('/lang/{locale}not
Route::get('lang/{locale}and
href="/lang/en"not
href="lang/en"this is my favourite way to do it after reading the instructions, however I found that you get a 404 error when a parameter is used in the URL. If I have a route that goes something like example.com/user/1 where 1 is the id of the user, the code breaks and instead of the translation occurring you get a 404... any fix for this?
