Laravel - send mail to queue with different connection - php

Question

I use this code to send invoice
Mail::send($email_template, $view_vars, static function ($m) use ($customer, $company, $email_subject, $users, $invoice, $invoice_name) {
$m->from($company->send_email, $company->name);
$m->to($users, $customer->getFullName())->subject($email_subject);
$m->attachData($invoice, $invoice_name);
});
Problem that it need some time to send email with atache.
Decision - to use Queue and change Mail::send() to Mail::queue()
But I use iron.io as as QUEUE Driver. And by default email with attached will go to iron.io - so it also need some time.
I whant to use database connection for this case.
can I use code:
Mail::queue(.......)->onConnection('database');
?
Table Jobs already exist.
After this need I some additional code that emails was realy sended in background ot it will be done automaticaly?

Answer 1

Tha best way is to use local connection method (databases) for all queues.

According to Laravel docs, you can use onConnection with Queues.
https://laravel.com/docs/8.x/queues#chain-connection-queue
To do extra processing after mail has been sent, you need to listen to Laravel's MailSent event.
https://laravel.com/api/5.5/Illuminate/Mail/Events/MessageSent.html
Define a listener in EventServiceProvider
'Illuminate\Mail\Events\MessageSent' => [
'App\Listeners\OnMessageSent',
]
Define handle function in the listener.
use Illuminate\Mail\Events\MessageSent;
class OnMessageSent {
// listen for MailSent event
public function handle(MessageSent $event)
{
if ($event) {
// do something here
dd($event);
}
}
}
