Creating Event and Listener

Create Laravel blade file and keep it in your app’s /src/Events folder.

/packages/vendor-name/project-name/
                    ├── src
                    │   ├── Events
                    │   │   ├── Uninstaling.php
                    │   │   ├── Uninstalled.php

Eloquent Model Events

Eloquent models fire several events automatically, allowing you to hook into the following points in a model's lifecycle: retrieved, creating, created, updating, updated, saving, saved, deleting, deleted, restoring, restored.

RVsitebuilder Application Events

You can find the full list of events using Artisan command.

php artisan event:list

Register Event on App’s Service Provider

php artisan make:event Installing

namespace VenderName\ProjectName\Events;

    class Installing
    {
        use SerializesModels;

        public function __construct(Request $request)
        {
            $this->request = $request;
        }

        public function broadcastOn()
        {
            return [];
        }
    }

Dispatching Events

To dispatch an event, you may pass an instance of the event to the event helper. you may call it from anywhere in your application:

namespace VenderName\ProjectName\Http\Controllers\Admin;

    class AppsController extends Controller
    {
        protected function uninstall(UninstallRequest $request)
        {
            event(new Uninstalling($request));

            Apps::uninstall($request);

            event(new Uninstalled($request));

        }
    }

Register Listener on App’s Event Service Provider

/packages/vendor-name/project-name/
                    ├── src
                    │   ├── Listeners
                    │   │   ├── Uninstaling.php
                    │   │   ├── Uninstalled.php
                    │   │   |   ├── Blog.php
                    │   │   |   ├── page.php

Listener

Set Listeners On App’s EventServiceProvider.php

namespace VenderName\ProjectName;

use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

    class EventServiceProvider extends ServiceProvider
    {
        protected $listen = [
        \VenderName\ProjectName\Events\Uninstaling::class => [
        ],

        \VenderName\ProjectName\Events\Uninstalled::class => [
            \VenderName\ProjectName\Listeners\Uninstalled\Blog::class,
            \VenderName\ProjectName\Listeners\Uninstalled\Page::class,
        ],
    }

Dispatching Listeners

Event listeners receive the event instance in their handle method. you may perform any actions necessary to respond to the event:

namespace VenderName\ProjectName\Listeners\Uninstalled;

class Blog
{
    /*
     * event(new Uninstalled($request));
     */
    public function handle(Uninstalled $event)
    {
        $manageApp = ManageApp::withTrashed()
                                ->where('app_name', $event->request->appsName)
                                ->pluck('enabled_data')
                                ->first();

        $data = collect(json_decode($manageApp, true))->recursive();

        if ($data->get('post')->has('id')) {
            BlogPost::withTrashed()
                    ->whereIn('id', $data->get('post')->get('id')->toArray())
                    ->forceDelete();
        }
    }
