Multilingualism in Laravel 11

I am working on multilingualism using the mcamara library

This is what I did: In the laravellocalization.php file I activated the Arabic and English languages

In the boostrab/app.php file, I added the middleware as shown in the library itself

->withMiddleware(function (Middleware $middleware) {
        $middleware->alias([
            /**** OTHER MIDDLEWARE ALIASES ****/
            'localize'                => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRoutes::class,
            'localizationRedirect'    => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRedirectFilter::class,
            'localeSessionRedirect'   => \Mcamara\LaravelLocalization\Middleware\LocaleSessionRedirect::class,
            'localeCookieRedirect'    => \Mcamara\LaravelLocalization\Middleware\LocaleCookieRedirect::class,
            'localeViewPath'          => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationViewPath::class,
        ]);
    })

In the routes/web.php file

Route::prefix(LaravelLocalization::setLocale())
->middleware([ 'localeSessionRedirect', 
        'localizationRedirect', 
        'localeViewPath',
        'localeCookieRedirect'])
->group(function(){
Route::get('create_offer',[OfferController::class,'create']);

});

In the lang/ar/message.php file

'name_required' => 'الاسم مطلوب',
'next' => 'Next »',

In the lang/en/message/php file

'name_required' => 'The Name Required',
'next' => 'Next »',

In the controller file

class OfferController extends Controller
{
    public function store(Request $request){
        $rq = $request->validate([
            'name'=>'required|unique:offers',
            'price'=>'required',
            'details'=>'required'
        ],
    [
        'name.required'=>__('message.name_required')
    ]);
        $inserted = Offer::create(
            
                $rq
            );
            return redirect()->back()->with(['message' => 'تم اضافة العرض بنجاح']);
 
    }

    public function create(){
        return view('offers.create');
    }
}

In the blade file

@foreach(LaravelLocalization::getSupportedLocales() as $localeCode => $properties)
        <li class="nav-item">
            <a class="nav-link" rel="alternate" hreflang="{{ $localeCode }}"  href="{{ LaravelLocalization::getLocalizedURL($localeCode, null, [], true) }}">{{ $properties['native'] }}</a>
        </li>
    @endforeach

What I expect is that when I press the English language button, the language is converted to English, and when I press the Arabic language button, it is converted to Arabic.

Expected when pressing the english button: The word الاسم مطلوب has been changed from Arabic to English But this did not happen. What happens when you press the English button, the word remains the same in Arabic I don't know how to solve this problem

I was able to solve the problem after many attempts, and I would like to share the solution with you so that everyone can benefit from it

What I did was omit the Mcamara laravel-localization library

Then I did this thing inside the store function:

 public function store(Request $request , $lang=''){
        if(in_array($lang,['en','ar'])){
            App::setLocale($lang);
            Session::put('lang',$lang);
        }else{
            App::setLocale(Session::get('lang'));
            Session::put('lang',App::getLocale());
        }
       //.............
     }
    

What was added inside the function store is a variable named lang whose value is sent when entering the route of the function store. The variable values ​​are checked and the value is added inside App::getLocale() and also inside Session::put(). If the value of the variable lang is null, App::setLoale() is made to take the value from Session.

This is the Route of the store function:

Route::post('insert_offer/{lang?}',[OfferController::class,'store'])->name('store_offer');

The same thing was done inside the function create

public function create($lang=''){
        if(in_array($lang,['en','ar'])){
            App::setLocale($lang);
            Session::put('lang',$lang);
        }else{
            App::setLocale(Session::get('lang'));
            Session::put('lang',App::getLocale());
        }
        return view('offers.create',['language'=>['العربية'=>'ar','English'=>'en']]);
    }

This is the Route of the create function:

Route::get('create_offer/{lang?}',[OfferController::class,'create']);

The value of the variable lang is sent to the function store via form.

Like this:

<form method="post" action="{{ route('store_offer',App::getLocale()) }}">

I hope everyone benefits from this and bye

I want to add some modifications just for those who want to use the Request Validation files:

Inside the roles function we will place the same verification code as before, but with a slight difference:

public function rules(): array
    {
        $lang = request()->input('lang');
        if(in_array($lang,['en','ar'])){
            App::setLocale($lang);
            Session::put('lang',$lang);
        }else{
            App::setLocale(Session::get('lang'));
            Session::put('lang',App::getLocale());
        }
       //.............
    

Here the value of lang is taken from the sent request

The value of lang is sent with request through input hidden

<input type="hidden" name="lang" value="{{ App::getLocale() }}">
