Where to setLocale in laravel 5 on multilingual - multidomain app

I'm also searching for the best answer for language preference. I just publish a small demo on Social Login with a language selection in the home page. Demo is visible at http://oidconnect.breizhme.net/demo/openidconnect/home

The only working model, I found it to store my user language preference in session and then retrieve it from controller constructor. I also tried to retrieve it from route.php but it looks like this file is executed before the session is in place. I then tried in access middleware. But even if in middleware I can retrieve language from user session, if I do a App::setLocale($lang) as this level it is forgotten before I reach my controller.

In ended up with following call in my controller parent class. It works, but I'm not sure that it is be the place where it should be.

    public function __construct () {
        $lang = Session::get ('locale');
        if ($lang != null) \App::setLocale($lang);
    }

I made an App middleware set in global stack after Illuminate ones to manage locale and other stuff. It works fine.

BrestMono could explain your "in global stack after Illuminate". When I try 'App::setLocale($lang);' the selection was lost before I enter my controllers.

Question: where do you declare your Middleware in order to make the called automatic for every pages and late enough for the selection to be still valid where entering Controllers methods ?

Anywhere in the protected $routeMiddleware array of the app/Http/Kernel.php file.

    /**
     * The application's route middleware.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => 'Asgard\Http\Middleware\Authenticate',
        'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
        'guest' => 'Asgard\Http\Middleware\RedirectIfAuthenticated',
        'locale' => 'Your\Middleware\Namespace',
    ];

Then you can localize routes :

$router->group(['middleware' => 'locale'], function($router)
{
  $router->get('a/localized/route', ...);
});

@fulup there :

/**
 * The application's global HTTP middleware stack.
 *
 * @var array
 */
protected $middleware = [
    'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
    'Illuminate\Cookie\Middleware\EncryptCookies',
    'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
    'Illuminate\View\Middleware\ShareErrorsFromSession',
    'Illuminate\Foundation\Http\Middleware\VerifyCsrfToken',
    'App\Http\Middleware\App'
];

This is almost what I tried and I was loosing my language preference. Are your using \App::setLocale($lang); call or something else in your middleware ?

@fulup this is my middleware :

<?php namespace App\Http\Middleware;

use Closure, Session, Auth;

class App {

    /**
     * The availables languages.
     *
     * @array $languages
     */
    protected $languages = ['en','fr'];

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(!Session::has('locale'))
        {
            Session::put('locale', $request->getPreferredLanguage($this->languages));
        }

        app()->setLocale(Session::get('locale'));

        if(!Session::has('statut')) 
        {
            Session::put('statut', Auth::check() ?  Auth::user()->role->slug : 'visitor');
        }

        return $next($request);
    }

}

You can see it in action in my example.

I created a middleware like that:

<?php namespace App\Http\Middleware;

use Closure;
use Session;
use App;
use Config;

class Locale {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $language = Session::get('language', Config::get('app.locale'));
        App::setLocale($language);

        return $next($request);
    }

}

and added it to protected $middleware array of App/Http/Kernel.php which will make it loaded automatically.

    /**
     * The application's global HTTP middleware stack.
     *
     * @var array
     */
    protected $middleware = [
        'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
        'Illuminate\Cookie\Middleware\EncryptCookies',
        'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
        'Illuminate\Session\Middleware\StartSession',
        'Illuminate\View\Middleware\ShareErrorsFromSession',
        'App\Http\Middleware\VerifyCsrfToken',
        'App\Http\Middleware\Locale',
    ];

Hi. I have created a new LocaleController to change the locale option using cookies

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
use URL;
use Cookie;

class LocaleController extends Controller {

    public function setLocale($locale = 'en')
    {
        if (! in_array($locale,['en','es']))
        {
            $locale = 'en';
        }
        Cookie::queue('locale', $locale);
        return redirect(url(URL::previous()));
    }
}

And a route like this:

...
Route::get('locale/{locale?}',
    [
        'as' => 'locale.setlocale',
        'uses' => 'LocaleController@setLocale'
    ]);
...

So the Locale middleware needs to be modified to this

<?php namespace App\Http\Middleware;
use Carbon\Carbon;
use Closure;
use App;
use Config;

class Locale {
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $locale = $request->cookie('locale', Config::get('app.locale'));
        App::setLocale($locale);
        Carbon::setLocale($locale);

        return $next($request);
    }
}

Yours.

hi guys can you tell me which process to set locale is best against speed,loading time span

Does this work like a language switcher with routes or just an over all site language setting?

Hi omar.makled, Please can you advice? Why redirect to login page and no change language. I did everything by your instructions.

Didn't work for me. session('locale') is in null before middleware.

I tried this way...

created new request class LocaleRequest and inject this request in controller methods.

LocalRequest.php

`<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest; use App;

class LocaleRequest extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return true; }

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    App::setLocale(session('locale', 'en'));

    return [
        //
    ];
}

`
