Set Lang with Cookie

@giogiosw Maybe edit the config/app.php file with...

Top of file... Elvis operator saying if there is a cookie value for lang, use that... otherwise use en

<?php

$language = cookie('lang') ?: 'en';

return [

Change this mid-file... pass the cookie lang or en to the config.

    /*

    */

    'locale' => $language,

i have this error:

Having it in ServiceProvider should work. I'm not sure from your post if defining it in ServiceProvider is working for you or not?

@giogiosw Actually, put it in the boot method of AppServiceProvider.

public function boot()
{
    // Set locale from cookie, otherwise use default app config setting...
    app()->setLocale( cookie('lang') ?: config('app.locale') );
}

@fylzero I tried but it doesn't work.

It appears that the cookie is not read correctly in the file.

@bugsysha I can't understand why it doesn't work

@giogiosw

Set client cookie... 20 mins

Cookie::queue( Cookie::make('lang', 'es', 20) );

Set client cookie... forever

Cookie::queue( Cookie::forever('lang', 'es') );

Get cookie...

Cookie::get('lang');

The cookie() helper was returning weird for me as well. Make sure you explicitly use the facade use Illuminate\Support\Facades\Cookie;

I guess queue allows the cookie to be attached to the response headers so it can be set on the clients machine. I thought this happened implicitly, it doesn't seem to. I rarely reach for cookies for this. Usually I set these types of things in the session, which uses a cookie anyway, just seems easier to deal with.

In fact, you might just want to use that approach. Store the language preference in the database and then save that to the session on login. That would be more robust because then the setting would save across different machines the user may be using.

Just dropping a language cookie off... if the user goes on their phone or on a different computer, their language would revert to default. Something to consider.

@giogiosw Just figured out... in AppServiceProvier the cookie is still encrypted... still trying to figure this out for ya...

@fylzero In fact it is encrypted and is not read .. Very strange.

@giogiosw I would just do this... it is a bit excessive... but...

Create middlewear to check for a language cookie.

php artisan make:middleware SetLocale

app/Http/Middleware/SetLocale.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Cookie;

class SetLocale
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        // You can optimize / cache this probably so you aren't actually checking for it on every request.
        // .Not sure if that is expensive really / probably not.  Depends on what scale you're working with.
        App::setLocale( Cookie::get('lang') ?: config('app.locale') );

        return $next($request);
    }
}

app/Http/Kernel.php

    protected $routeMiddleware = [
        // Everything else
        'set.locale' => \App\Http\Middleware\SetLocale::class,
    ];

app/Providers/RouteServiceProvider.php

protected function mapWebRoutes()
{
    Route::middleware(['web', 'set.locale'])
            ->namespace($this->namespace)
            ->group(base_path('routes/web.php'));
}

Just drop the cookie on the user machine like this..

Cookie::queue( Cookie::make('lang', 'es', 20) );

I just testing this... looks like it works fine. By editing the RouteServiceProvider and adding the middleware to web routes... that will automatically apply the middleware to anything in the web.php route file.

Again, I'd still reconsider using session for this purpose. Seems more robust / proper.

Cookie encryption middleware is not active at that point in Service Providers so that is why you are getting encrypted values.

@bugsysha Yeah, I still have a lot to learn about lifecycle stuff in Laravel.

I could not remember why but I guess this is the reason why I always used language as part of the URL.

@fylzero Thk for you help :) The code works
