In Laravel, middleware can be used to handle various tasks, including setting the locale. However, accessing the session in global middleware can be tricky, especially when dealing with routes that don't exist (like a 404 error).
To access the session in global middleware, you need to ensure that the session is started before your middleware runs. Here's a step-by-step solution:
Create a Global Middleware:
First, create a new middleware using the Artisan command:
php artisan make:middleware SetLocale
Modify the Middleware:
In your SetLocale middleware, you can access the session and set the locale. Here's an example of how you might do it:
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Session;
class SetLocale
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
// Check if the session has a 'locale' key
if (Session::has('locale')) {
// Set the application locale
App::setLocale(Session::get('locale'));
}
return $next($request);
}
}
Register the Middleware:
To ensure this middleware runs globally, you need to register it in the app/Http/Kernel.php file. Add it to the $middleware array:
protected $middleware = [
// Other middleware
\App\Http\Middleware\SetLocale::class,
];
Ensure Session Middleware is Loaded:
The session middleware should be loaded before your custom middleware. Laravel's default session middleware is usually included in the web middleware group. However, since you're dealing with global middleware, ensure that the session is started by including \Illuminate\Session\Middleware\StartSession::class in the $middleware array if it's not already there.
Handling 404 Errors:
Since 404 errors might bypass the web middleware group, having your locale setting middleware globally ensures it runs even on non-existent routes.
By following these steps, you should be able to set the locale using session data in a global middleware, even when handling 404 errors.
This is my code...I can grab the session object with no problems. But storing the locale is not working. When it comes back the Session Object array is blank. Session::all() returns nothing in the array after it is set.
Sorry for the bad formatting how do I get my code to code format, so it is easier to read for you all?
namespace App\Http\Middleware;
use App\Enums\Languages;
use Closure;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Auth;
use Session;
class SetLocale
{
public function handle($request, Closure $next)
{
if (Auth::check() and Auth::user()->lang) {
App::setLocale(Auth::user()->lang);
}
elseif (Session::has('locale')) {
App::setLocale(Session::get('locale'));
Session::put('locale_text', Languages::from(Session::get('locale'))->label());
}
else{
App::setLocale(config('app.fallback_locale'));
Session::put('locale',config('app.fallback_locale') );
Session::put('locale_text', Languages::from(Session::get('locale'))->label());
}
Solution: Using Global Middleware
You can create a middleware that sets the locale based on the request and register it globally.
Create a Middleware
php artisan make:middleware SetLocale
Update the Middleware
Modify the generated middleware (app/Http/Middleware/SetLocale.php) to set the locale:
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\App;
class SetLocale
{
public function handle(Request $request, Closure $next)
{
// Get the locale from session, request, or default
$locale = $request->getPreferredLanguage(['en', 'fr', 'es', 'de']) ?? 'en';
// Set application locale
App::setLocale($locale);
return $next($request);
}
}
Register Middleware Globally
In Laravel 11, middleware registration happens in app/Http/Kernel.php. Open the file and add your middleware to the $middleware array:
protected $middleware = [
\App\Http\Middleware\SetLocale::class,
];
Clear Cache and Test
php artisan config:clear
php artisan cache:clear
