Email configuration dynamically not changing from database in loop - php

Question

I apply a foreach loop in the email configuration SMTP settings dynamically from database.there are multiple SMTP servers in the SMTP server table. I am selecting the SMTP information dynamically from the table according to smtp_server_id from processing table and storing it in an email configuration before sending the email on the fly. But on the first iteration, the SMTP servers that come from dB are stored on email configuration like as config('mail.smtp.host') but on the second iteration till the end of loop, the SMTP information do not change. The SMTP information remains the same and Mail Configuration variables remains same when they are on the first iteration. What should I do to change the SMTP configuration dynamically one one by one according to the smtp_id in foreach loop.
My cron job to send emails.
namespace App\Console\Commands;
use App\Mail\SendEmail;
use App\Models\CronjobSetting;
use App\Models\ProcessingEmail;
use App\Models\SmtpServer;
use Carbon\Carbon;

use Illuminate\Support\Facades\Mail;
class SendEmailsBasedonDate extends Command

/**

protected $signature = 'sendemailviadate:cron';
/**

protected $description = 'Command description';
/**

public function __construct()
{
parent::__construct();
}
/**

public function handle()
{
$cronJob = CronjobSetting::whereDate('created_at', Carbon::today())->first();
if ($cronJob->email_group_type == 1) {
$processingEmails = ProcessingEmail::all();
foreach ($processingEmails as $processingEmail) {
$smtpServer = SmtpServer::where('id', $processingEmail->smtp_id)->first();
Config::set('mail.mailers.smtp.host', $smtpServer->hostname);
Config::set('mail.mailers.smtp.port', $smtpServer->port);
Config::set('mail.mailers.smtp.username', $smtpServer->username);
Config::set('mail.mailers.smtp.password', $smtpServer->password);
$email = new SendEmail($processingEmail);
Mail::to($processingEmail->recipient_email)->send($email);
if (Mail::failures()) {
ProcessingEmail::where('id', $processingEmail->id)->update(
['status' => 3]
);
} else {
ProcessingEmail::destroy($processingEmail->id);
}
}
} else {
$processingEmails = ProcessingEmail::where('email_group_id', $cronJob->email_group_id)->get();
foreach ($processingEmails as $processingEmail) {
$smtpServer = SmtpServer::where('id', $processingEmail->smtp_id)->first();
Config::set('mail.mailers.smtp.host', $smtpServer->hostname);
Config::set('mail.mailers.smtp.port', $smtpServer->port);
Config::set('mail.mailers.smtp.username', $smtpServer->username);
Config::set('mail.mailers.smtp.password', $smtpServer->password);
$email = new SendEmail($processingEmail);
Mail::to($processingEmail->recipient_email)->send($email);
if (Mail::failures()) {
ProcessingEmail::where('email_leads_id', $processingEmail->email_lead_id)->update(
['status' => 3]
);
} else {
ProcessingEmail::where('email_leads_id', $processingEmail->email_lead_id)->delete();
}
}
return Command::SUCCESS;
}
}
}

Answer 1

SO I will give you two options
one: register the MailServiceProvider after new config.
(new \Illuminate\Mail\MailServiceProvider(app()))->register();
two: creating a new Instance of swift mailer
<?php
$transport = (new \Swift_SmtpTransport('host', 'port'))
->setEncryption(null)
->setUsername('username')
->setPassword('secret')
->setPort($port);
$mailer = app(\Illuminate\Mail\Mailer::class);
$mailer->setSwiftMailer(new \Swift_Mailer($transport));
$mail = $mailer
->to('user#laravel.com')
->send(new SendEmail($processingEmail));
Basically, you are creating a new Instance of swift mailer here and adding providing to laravel mailer.
