laravel：要在每个视图上使用的全局值

I am creating a login site with laravel. Is there a way that I can store the user's name on a variable where it can be called on the page?

I know I can store it in a session like Session::put('loginName', Auth::user()->name);

but this then I would have to also retrieve this user's name on every controller using $loginName = Session::get('loginName'); return View::make('dashboard/index')->with('loginName', $loginName);

and to get it from the view file with {{$loginName}}

I just wonder if there is a short cut so I don't have to repeat this on every controllers

In your routes.php file, do this:

if(Auth::check()){
    $name = Auth::user()->name;
}else{
    $name = 'Guest';
}
View::share('name', $name);

In your view files:

{{ $name }}
