How to change language dinamically in laravel? - php

Question

I added a button to change language.
This is my controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\RedirectResponse;
class LanguageController extends Controller
{
public function __invoke(String $locale): RedirectResponse
{
app('session')->put('language', $locale);
app()->setLocale($locale);
return redirect()->back();
}
}
My routes:
<?php
use App\Http\Controllers\LanguageController;
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('auth.login');
});
Route::get('/language/{locale}', LanguageController::class)->name('locale');
require __DIR__.'/auth.php';
And I put this in my blade:
#if (app()->getLocale() == 'es')
<x-responsive-nav-link :href="route('locale', ['locale' => 'en'])">
{{ __('English') }}
</x-responsive-nav-link>
#else
<x-responsive-nav-link :href="route('locale', ['locale' => 'es'])">
{{ __('Spanish') }}
</x-responsive-nav-link>
#endif
I tested it changing the locale directly in the config/app.php file and it works.
Also tried to set the locale in the AppServiceProvider but session variable "language" is not set (even though it is on the controller).
How could I do this?

My version.Right now this is the best way for me.
Route:
Route::get('locale/{locale}', function ($locale) {Session::put('locale', $locale);return redirect()->back();})->name('locale');
HeaderController function index:
public function index(): Factory|View|Application
{
$data['languages'] = Language::where('status', '=', 1)->get();
//Get or Set current language
$get_default_lang = 'uk';
$default_lang = $get_default_lang ?? 'en';
if (session()->get('locale') == null) Session::put('locale', $default_lang);
//Get Current Language
$get_current_lang = Session::get('locale');
$session_language = Language::where('code', $get_current_lang)->first();
$data['current_language_name'] = $session_language['name'];
$data['current_language_image'] = url($session_language['image']);
return view('common/header', ['data' => $data]);
}
Header Blade:
<div class="dropdown">
<button type="button" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<img src="{{ $data['current_language_image'] }}" alt="{{ $data['current_language_name'] }}" style="max-width:20px;margin-right:5px;" />
{{ $data['current_language_name'] }}
</button>
<div class="dropdown-menu">
<div class="p-2">
#foreach($data['languages'] as $language)
<a href="{{ route('locale', ['locale' => $language->code]) }}" class="dropdown-item d-flex align-items-center justify-content-between">
<img src="{{ url($language->image) }}" alt="{{ $language->name }}" style="max-width:20px;" />
<span>{{ $language->name }}</span>
</a>
#endforeach
</div>
</div>
</div>
Language migration:
Schema::create('language', function (Blueprint $table) {
$table->bigIncrements('language_id');
$table->string('name', 32);
$table->string('code', 5);
$table->string('image')->nullable();
$table->tinyInteger('status');
$table->timestamps();
});
