php - How to pass data to all views in Laravel 5?

Question

I want to have some default data accessible in all views in my Laravel 5 application.

I have tried to search for it but only find results for Laravel 4. I have read the documentation 'Sharing Data With All Views' here but I can't understand what to do. Where should the following code be placed?

View::share('data', [1, 2, 3]);

Thanks for your help.

Answer 1

This target can achieve through different method,

1. Using BaseController

The way I like to set things up, I make a BaseController class that extends Laravel’s own Controller, and set up various global things there. All other controllers then extend from BaseController rather than Laravel’s Controller.

class BaseController extends Controller
{
  public function __construct()
  {
    //its just a dummy data object.
    $user = User::all();

    // Sharing is caring
    View::share('user', $user);
  }
}

2. Using Filter

If you know for a fact that you want something set up for views on every request throughout the entire application, you can also do it via a filter that runs before the request — this is how I deal with the User object in Laravel.

App::before(function($request)
{
  // Set up global user object for views
  View::share('user', User::all());
});

OR

You can define your own filter

Route::filter('user-filter', function() {
    View::share('user', User::all());
});

and call it through simple filter calling.

Update According to Version 5.*

3. Using Middleware

Using the View::share with middleware

Route::group(['middleware' => 'SomeMiddleware'], function(){
  // routes
});



class SomeMiddleware {
  public function handle($request)
  {
    View::share('user', auth()->user());
  }
}

4. Using View Composer

View Composer also help to bind specific data to view in different ways. You can directly bind variable to specific view or to all views. For Example you can create your own directory to store your view composer file according to requirement. and these view composer file through Service provide interact with view.

View composer method can use different way, First example can look alike:

You could create an AppHttpViewComposers directory.

Service Provider

namespace AppProviders;
use IlluminateSupportServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("ViewName","AppHttpViewComposersTestViewComposer");
    }
}

After that, add this provider to config/app.php under "providers" section.

TestViewComposer

namespace AppHttpViewComposers;

use IlluminateContractsViewView;

class TestViewComposer {

    public function compose(View $view) {
        $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
    }
}

ViewName.blade.php

Here you are... {{$ViewComposerTestVariable}}

This method could help for only specific View. But if you want trigger ViewComposer to all views, we have to apply this single change to ServiceProvider.

namespace AppProviders;
use IlluminateSupportServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer('*',"AppHttpViewComposersTestViewComposer");
    }
}
