Laravel: How to access session value in AppServiceProvider? - php

Question

Is there any way available to access Session values in AppServiceProvider? I would like to share session value globally in all views.

Answer 1

You can't read session directly from a service provider: in Laravel the session is handled by StartSession middleware that executes after all the service providers boot phase
If you want to share a session variable with all view, you can use a view composer from your service provider:
public function boot()
{
view()->composer('*', function ($view)
{
$view->with('your_var', \Session::get('var') );
});
}
The callback passed as the second argument to the composer will be called when the view will be rendered, so the StartSession will be already executed at that point

Answer 2

Add new web middleware ShareDataForView
in \app\Http\Kernel.php:
protected $middlewareGroups = [
'web' => [
// ...
\Illuminate\Session\Middleware\StartSession::class,
// I will always ShareDataForView after StartSession
\App\Http\Middleware\ShareDataForView::class,
...
and write your code in method "handle" of app\Http\Middleware\ShareDataForView.php, for example:
<?php
namespace App\Http\Middleware;
use Illuminate\Support\Arr;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Str;
use Closure;
use Log, Exception, View;
class ShareDataForView
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$user = Auth::user();
$bank = NULL;
if ( $user ){
$bank = $user->bank;
}
View::share('user', $user);
session()->put(['bank' => $bank]);
return $next($request);
}
}

The following works for me on Laravel 5.2, is it causing errors on your app?
AppServiceProvider.php
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
\Session::put('lang', 'en_US');
view()->share('lang', \Session::get('lang', 'de_DE'));
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}
home.blade.php
<h1>{{$lang}}</h1>
Shows "en_US" in the browser.
