Language setLocale - not working.

Trying to make the app multi lang. This client has Laravel 7.x so i need to upgrade on a later date. For now, i want to update the menu to be multi lang. I create a json file for en.json fr.json and es.json /resources/lang

en.json
{
    "Login": "Login",
}

es.json
{
    "Login": "Ingresar",
}

And the route looks like this

Route::get('/lang/{locale}', function ($locale) {

    if (!in_array($locale, ['en', 'fr','es'])) {
        abort(400);
    }

    App::setLocale($locale);

    return redirect()->back();

});

and the view looks like this...

<h3 class="text-center mb-3">{{ trans('Login') }}   </h3>
<h3 class="text-center mb-3">{{ __('Login') }}   </h3>

Problem is that it does not work. It will not change the language. However, if change the config/app.php to

    'locale' => 'es',

it works......

anyone please?

To ensure the consistent application of the selected locale, it is necessary to store the locale in the session. so update your route:

Route::get('/lang/{locale}', function ($locale) {

    if (!in_array($locale, ['en', 'fr','es'])) {
        abort(400);
    }

    App::setLocale($locale);
	session()->put('locale', $locale);

    return redirect()->back();

});

create a middleware that examines the locale stored within the session,

artisan make:middleware Localization

namespace App\Http\Middleware;

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

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

add the newly created middleware into your kernel.php file, within the middlewareGroups array, to enable its functionality throughout your application's request lifecycle.

protected $middlewareGroups = [
        'web' => [
            ...
			\App\Http\Middleware\Localization::class,
        ]
];

now, your application will utilize the selected locale for all of its pages

@Rebwar thank you! just same a small change to your code...

    public function handle($request, Closure $next)
    {

        if( Session::has('locale') ) {

            App::setLocale( Session::get('locale') );
        
        } else {
        
            App::setLocale( config('app.fallback_locale') );
        
        }

        return $next($request);

    }
