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

Passing Data to All Views in Laravel 5

In Laravel 5, sharing data among all views can be achieved through various methods.

Method 1: Using BaseController

Create a BaseController class that extends Laravel's Controller.

class BaseController extends Controller
{
    public function __construct()
    {
        $data = [1, 2, 3];
        View::share('data', $data);
    }
}

All other controllers should then extend from BaseController:

class SomeController extends BaseController {
    // ...
}

Method 2: Using Filter

Create a filter in app/filters.php or in a separate filter class file:

App::before(function($request) {
    View::share('data', [1, 2, 3]);
});

Alternatively, define a custom filter:

Route::filter('data-filter', function() {
    View::share('data', [1, 2, 3]);
});

Apply the filter to specific routes using Route::filter().

Method 3: Using Middleware

Pass data using middleware to views:

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

class SomeMiddleware
{
    public function handle($request)
    {
        View::share('data', [1, 2, 3]);
    }
}

Method 4: Using View Composer

Bind data to views using View Composer. This allows you to bind data to specific views or all views.

To bind data to a specific view, create a ViewComposer class and register it in the service provider:

// ViewComposer
use Illuminate\Contracts\View\View;

class DataComposer
{
    public function compose(View $view)
    {
        $view->with('data', [1, 2, 3]);
    }
}

// Service Provider
public function boot() {
    view()->composer('view-name', 'DataComposer');
}

To bind data to all views, use the following code in the service provider:

view()->composer('*', 'DataComposer');
