Laravel - 在所有路线上请求提供商数据

Question

I am currently using a Laravel Provider to pass data to a view each time it is called. The App.blade.php includes the blade file if the user is authenticated.

My problem is that at the moment, no matter what view the user is on, it still calls the ViewServiceProvider.php, which doesn't seem very efficient.

I have tried to use @if(view()->exists('home')), but that doesn't seem to have any effect what so ever, and thus, the queries are still called from the ViewServiceProvider.php.

App.blade.php:

@if(!Auth::guest())

  @if(view()->exists('home'))

    @include('layouts.check')

  @endif

@endif

ViewServiceProvider.php:

public function boot()
    {
      view()->composer('layouts.check', function ($view) {

        $sites = Site::where('trust_id', Auth::id())->get();

        $view->with(['sites' => $sites]);
      });
    }

Any help would be hugely appreciated.

The problem with you code is that it's check to see if the view exists. Chances are, the view "home" will always exist, so it will always include your view; "layouts.check".

Unless, of course, the view "home" is dynamic and is only there conditionally, which doesn't seem right. If you want the "layouts.check" view file to only load on certain pages, you might want to try "Request::is()".

@if(Request::is('home'))
    @include('layouts.check')
@endif
