Laravel Blade Templates Sharing data to all views
Example
Sometimes you need to set the same data in many of your views.
Using View::share
// "View" is the View Facade
View::share('shareddata', $data);
After this, the contents of $data will be available in all views under the name $shareddata.
View::share is typically called in a service provider, or perhaps in the constructor of a controller, so the data will be shared in views returned by that controller only.
Using View::composer
View composers are callbacks or class methods that are called when a view is rendered. If you have data that you want to be bound to a view each time that view is rendered, a view composer can help you organize that logic into a single location. You can directly bind variable to a specific view or to all views.
Closure-based composer
use Illuminate\Support\Facades\View;
// ...
View::composer('*', function ($view) {
$view->with('somedata', $data);
});
Class-based composer
use Illuminate\Support\Facades\View;
// ...
View::composer('*', 'App\Http\ViewComposers\SomeComposer');
As with View::share, it's best to register the composers in a service provider.
If going with the composer class approach, then you would have App/Http/ViewComposers/SomeComposer.php with:
use Illuminate\Contracts\View\View;
class SomeComposer
{
public function compose(View $view)
{
$view->with('somedata', $data);
}
}
These examples use '*' in the composer registration. This parameter is a string that matches the view names for which to register the composer (* being a wildcard). You can also select a single view (e.g. 'home') of a group of routes under a subfolder (e.g. 'users.*').
