How Can I Make Data Globally Accessible Across All Views in Laravel 5?

How to Make Data Globally Accessible in Laravel 5 Views

Introduction
Passing data to all views in Laravel 5 applications can enhance code reusability and provide a consistent data context across views. This article explores various methods to achieve this in Laravel 5.

Using BaseController
This approach involves creating a BaseController class that extends Laravel's Controller class. Global data can be set within the __construct() method of the BaseController class, and all other controllers that inherit from BaseController will have access to this data.

class BaseController extends Controller
{
    public function __construct()
    {
        // Access your global data here
        $user = User::all();
        View::share('user', $user);
    }
}

Using Filters
Filters provide a mechanism to execute code before every request. Global data can be set within the before filter, making it available to all views.

App::before(function($request)
{
    // Access your global data here
    View::share('user', User::all());
});

Using Middleware
In Laravel 5, middleware provides a more powerful filtering mechanism. Similar to filters, global data can be set within middleware's handle method.

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

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

Using View Composer
View composers allow you to bind specific data to views. Global data can be bound to all views by using a View Composer service provider.

// Service Provider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("*", "App\Http\ViewComposers\TestViewComposer");
    }
}

// View Composer
namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;

class TestViewComposer {

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

Conclusion
This article provides multiple methods to pass data to all views in a Laravel 5 application, enabling developers to maintain a consistent data context and enhance code reusability. The choice of method depends on specific requirements and preferences.
