How to change locale of a blade file

Question

We are using IP2LOCATIONLARAVEL for getting visitors' country codes. If the visitor's IP is from Iran (ISO country code = IR), the lang attribute of the html tag in blade.php must be set as 'fa', otherwise as 'en'.

Firstly, we added this line to our config/app.php:

'locale' => 'en',
// we added:
'other_locale' => ['fa-IR'],

We also created a middleware and added it in app/Http/kernel.php properly.

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Illuminate\Foundation\Application;
use Ip2location\IP2LocationLaravel\Facade\IP2LocationLaravel;

class LocaleHandler
{
    public function __construct(Application $app, Request $request) {
        $this->app = $app;
        $this->request = $request;
    }

    public function handle($request, Closure $next)
    {
        if (app()->getLocale()=='fa'){
            if(in_array($request->segment(0), config('app.other_locale'))){
                $this->app->setLocale($request->segment(0));
            }else{
                $this->app->setLocale(config('app.locale'));
            }
        }

        return $next($request);
    }
}

Then we updated app/Providers/RouteServiceProvider.php:

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Route;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Http\Request;

class RouteServiceProvider extends ServiceProvider
{

    protected $namespace = 'App\Http\Controllers';

    public function boot()
    {
        parent::boot();
    }


    public function map(Request $request)
    {
        $this->mapApiRoutes();
        $this->mapWebRoutes($request);
    }


    protected function mapWebRoutes(Request $request)
    {
        if(in_array($request->segment(0), config('app.other_locale'))){
            $locale = $request->segment(0);

        }else{
            $locale = null;
        }

        Route::group([
            'middleware' => 'web',
            'namespace' => $this->namespace,
            'prefix' => $locale
        ], function ($router) {
            require base_path('routes/web.php');
        });

        Route::middleware('web')
            ->namespace($this->namespace)
            ->group(base_path('routes/web.php'));
    }


    protected function mapApiRoutes()
    {
        Route::prefix('api')
            ->middleware('api')
            ->namespace($this->namespace)
            ->group(base_path('routes/api.php'));
    }
}

localhost/laravel/public/fa is 404 error page. how can we update

<html lang="{{ app()->getLocale() }}">

In our blade file, if visitor country code was IR?

It's hard to say what you really want to achieve. You should set valid locale in your PHP code and in Blade you just display it as you showed. — Marcin Nabiałek, Sep 27 '18 at 13:51
i have 1 blade file. i want setLocale to fa if visitor is from iran. i have an if-else(for checking visitor country code) but it doesn't work: setLocale. — Amin Shabanzadeh, Sep 27 '18 at 14:24
Take a look at answer, probably that's the problem that your middleware is never applied — Marcin Nabiałek, Sep 27 '18 at 14:29
note: Route::get('/',function() { return view('welcome'); }); — Amin Shabanzadeh, Sep 27 '18 at 14:40
The problem is that you don't have `/fa` route registered. So you should rethink your urls structure and reading https://stackoverflow.com/questions/25082154/how-to-create-multilingual-translated-routes-in-laravel might be helpful for you. — Marcin Nabiałek, Sep 27 '18 at 16:18

you sure added middleware in web in file kernel.php

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