Global view data for all actions in Laravel Blade
Laravel’s Blade is a great templating system that blends with Laravel’s ecosystem very well. Setting some data to the view is a breeze and rendering those data into the template is ever so easy. For instance, if you would like to share some data from a controller’s action to a view, you’d do like so.
class HomeController extends BaseController
{
public function __construct()
{
parent::__construct();
}
public function index()
{
return view('greetings', ['name' => 'Victoria']);
}
}
In the above example, a $name variable is available to be rendered in a blade template greetings.blade.php. You can pass around a lot more data similarly but you got the idea.
But what if you want to share some data across all controller actions? Read on to find out.
Using View::share for sharing data
In order to share common data across each view of the controller’s actions, you can use the Illuminate\Support\Facades\View facade’s share method by establishing a key-value pair like so which can then be accessible across all the actions’ views.
use Illuminate\Support\Facades\View;
class HomeController extends BaseController
{
public function __construct()
{
parent::__construct();
View::share('common_data', [
'foo' => 'bar'
]);
}
public function index()
{
return view('index');
}
public function show()
{
return view('show');
}
}
As you can see here, the $common_data will be available to each view, both index.blade.php and show.blade.php alike.
This is useful in scenarios for example there are menu items which are common across a particular set of actions and you don’t want to repeat the code over and over again.
