如何将一些变量只放到某些特定的视图中？

Question

I found in documentation that something similar can be done

But for all views

By putting in AppServiceProvider or other own ServiceProvider something like

View::share('key', 'value');

But how to share data only with some specific views?

Not all. Not one. But some views? Views listed im array or something that I want it to share

Answer 1

This is how I usually set up this kind of situation

In AppServiceProvider

public function boot()
{
      View::composer(
        ['home', 'profile.edit', 'projects.create'], // array of views
        function($view){
          $foo = \App\Foo::where('active', 1)->get();
          $bar = \App\Bar::all();
          $view->with(compact('foo', 'bar'));
        }
      );
}

Then in the views I passed to the array,I can reference my variables:

@foreach($foo as $item) :

@endforeach
