Generate PDF using job and then attach to queueable email

Level 58

To achieve this, you can use Laravel's queue system along with a combination of jobs and mailables.

First, create a job that generates the PDF. This job should implement the ShouldQueue interface to ensure it is queued for processing. Within the handle method of the job, you can generate the PDF and save it to a specific location. You can then pass the file path to the mailable.

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;

class GeneratePdfJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $user;
    protected $pdfFilePath;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function handle()
    {
        // Generate the PDF and save it to a specific location
        $pdf = generatePdf(); // Replace with your PDF generation logic
        $this->pdfFilePath = storage_path('app/pdf/' . $this->user->id . '.pdf');
        file_put_contents($this->pdfFilePath, $pdf);
    }

    public function getPdfFilePath()
    {
        return $this->pdfFilePath;
    }
}

Next, create a mailable that will send the email with the PDF attachment. In the build method of the mailable, you can attach the PDF file using the file path passed from the job.

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class SendPdfEmail extends Mailable
{
    use Queueable, SerializesModels;

    protected $pdfFilePath;

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

    public function build()
    {
        return $this->view('emails.pdf')
            ->attach($this->pdfFilePath, [
                'as' => 'document.pdf',
                'mime' => 'application/pdf',
            ]);
    }
}

Finally, in your controller or wherever you trigger the process, dispatch the GeneratePdfJob and pass the user to it. Once the job is completed, you can dispatch the SendPdfEmail mailable with the PDF file path.

use App\Jobs\GeneratePdfJob;
use App\Mail\SendPdfEmail;

public function sendPdfEmail(User $user)
{
    $generatePdfJob = new GeneratePdfJob($user);
    dispatch($generatePdfJob);

    $pdfFilePath = $generatePdfJob->getPdfFilePath();
    $sendPdfEmail = new SendPdfEmail($pdfFilePath);
    dispatch($sendPdfEmail);
}

This way, the PDF generation job will be queued and processed asynchronously. Once the job is completed, the mailable will be dispatched with the PDF file attached.

Note: Make sure to replace the placeholders (User, generatePdf(), emails.pdf, etc.) with your actual code and logic.
