Laravel: How to access session value in AppService

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

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.

Answer 2

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
