Share global data in Laravel views easily.

In web development, it is common to need to share data between different views to maintain the coherence and functionality of the application. Laravel, a popular PHP framework, offers various ways to do this efficiently. In this article, we will explore how to share global data across views in Laravel, making the work of developers easier and optimizing the user experience.

Why Share Global Data in Laravel?

Sharing global data is a useful practice in situations where the same information needs to be accessed in different parts of the application. This avoids redundancy and helps keep the code clean and organized. In Laravel, there are several ways to do this, and each approach has its advantages depending on the application's context.

Methods for Sharing Global Data

Middleware

One of the most common ways to share data in Laravel is through the use of middleware. Middleware are components that run before the request reaches the controller route. You can create a middleware that modifies the request or response, and in this process, you can share data accessible to all views.

To create a custom middleware, you can use the following command in the terminal:

php artisan make:middleware ShareGlobalData

Within the handle method of your middleware, you can add the logic to share the data:

public function handle($request, Closure $next)
{
    view()->share('key', 'value'); // Share data globally
    return $next($request);
}

Don't forget to register your middleware in app/Http/Kernel.php so that Laravel executes it on every request.

Base Controllers

Another way to share data is by extending a base controller. By creating a parent controller that contains common data, you can make all your controllers inherit from it. This is useful if your global data is related to the controller's logic.

An example of a base controller could be:

namespace App\Http\Controllers;

use Illuminate\Support\Facades\View;
use App\Models\User;

class BaseController extends Controller
{
    public function __construct()
    {
        $users = User::all(); // Get data
        View::share('users', $users); // Share in all views
    }
}

Then, you simply extend the BaseController in your other controllers:

class PostController extends BaseController
{
    public function index()
    {
        return view('posts.index');
    }
}

Service Providers

Service Providers are another option for sharing global data in Laravel. They are the application's entry point and allow access to and hosting of different services. You can use the boot method to share data across all views.

To do this, create a new Service Provider using the following command:

php artisan make:provider ViewServiceProvider

Then, share data in the boot method:

public function boot()
{
    view()->share('key', 'value'); // Share data globally
}

Don't forget to register the provider in config/app.php.

Conclusion

Sharing global data in Laravel is a straightforward task thanks to its multiple methods. Whether using middleware, base controllers, or service providers, each offers flexibility and organization in application development. Implementing these approaches not only simplifies data management but also optimizes the performance and maintainability of your code.
