To send parameters to a job in Laravel, you can use the `dispatch` method and pass the required arguments to the job's constructor. Here are the steps:
1. Define the Job Class:
- Create a job class that accepts parameters in its constructor. For example, `SiteCrawlerJob`:
php
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
class SiteCrawlerJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public function __construct(public Site $site, public Crawler $crawler)
{
// Constructor logic
}
public function handle(): void
{
// Job logic
}
}
2. Dispatch the Job:
- In your controller, dispatch the job with the required parameters:
php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use App\Jobs\SiteCrawlerJob;
use Illuminate\Http\Request;
use Illuminate\Http\RedirectResponse;
class PodcastController extends Controller
{
public function store(Request $request): RedirectResponse
{
$podcast = Podcast::create(/* ... */);
// Dispatch the job
SiteCrawlerJob::dispatch($podcast);
return redirect('/podcasts');
}
}
3. Passing Data to Jobs:
- You can pass data to jobs using the `dispatch` method. For example, if you need to pass a `Site` model and a `Crawler` instance:
php
public function store(Request $request): RedirectResponse
{
$podcast = Podcast::create(/* ... */);
// Dispatch the job
SiteCrawlerJob::dispatch(new SiteCrawlerJob($podcast));
return redirect('/podcasts');
}
4. Handling Multiple Parameters:
- If you need to pass multiple parameters to a job, you can create a Data Transfer Object (DTO) to encapsulate the data. For example, `SiteCrawlerTransporter`:
php
namespace App\Transporters;
use App\Models\Site;
use Symfony\Component\DomCrawler\Crawler;
class SiteCrawlerTransporter
{
public function __construct(public Site $site, public Crawler $crawler)
{
// Constructor logic
}
}
5. Using Pipelines:
- You can use Laravel's pipeline feature to process data through a series of tasks. For example, you can create a pipeline to crawl a site:
php
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\Pipeline;
class SiteCrawlerJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public function __construct(public Site $site)
{
// Constructor logic
}
public function handle(): void
{
// Pipeline logic
Pipeline::send(new SiteCrawlerTransporter($site, new Crawler(Http::get($site->domain)->body())))
->through([
function (SiteCrawlerTransporter $payload, Closure $next) {
// Process the payload
return $next($payload);
},
])
->thenReturn();
}
}
By following these steps, you can effectively pass parameters to jobs in Laravel and manage complex data processing tasks efficiently[1][2][3].
