How Can I Efficiently Share Data Across All Views in Laravel 5?

How to Effectively Share Data Across All Views in Laravel 5

The imperative of making certain data universally accessible throughout an application's views in Laravel 5 is frequently encountered by developers. This tutorial will meticulously guide you through several approaches to achieve this objective.

Sharing Data with BaseController

Establishing a BaseController class that extends Laravel's Controller provides a convenient means of initializing and sharing data globally. Other controllers can then inherit from BaseController instead of the default Controller.

class BaseController extends Controller
{
    public function __construct()
    {
        $user = User::all();
        View::share('user', $user);
    }
}

Utilizing Filters

Filters can be employed to ascertain that specific data is meticulously configured for every view on all requests:

App::before(function($request)
{
    View::share('user', User::all());
});

Alternatively, you can establish a bespoke filter and invoke it explicitly:

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

Route::group(['filter' => 'user-filter'], function() {
    // Define routes here
});

Leveraging Middleware

Middleware offers another streamlined approach to implementing data sharing across views.

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

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

Utilizing View Composers

View composers provide a flexible mechanism for binding distinct data to specific views. You can define composers that target individual views or apply to all views.

view()->composer("ViewName", "App\Http\ViewComposers\TestViewComposer");

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

In the ViewName.blade.php view:

{{ $ViewComposerTestVariable }}

To apply a view composer to all views, simply modify the service provider:

view()->composer('*', "App\Http\ViewComposers\TestViewComposer");

In conclusion, Laravel 5 offers a diverse array of approaches to sharing data across views, enabling developers to select the most suitable method based on their specific requirements.
