Symfony2 styled emails best practices - symfony

Question

What are the best practices to send emails from html & css? I have much mails in my projects & need the solution, that can allow me not to write all below code again & again:
$msg = \Swift_Message::newInstance()
->setSubject('Test')
->setFrom('noreply#example.com')
->setTo('user#example.com')
->setBody($this->renderView('MyBundle:Default:email1.text.twig'));
$this->get('mailer')->send($msg);

Answer 1

Maybe my answer can help. There is a special bundle Symfony2-MailerBundle that render email body from template and allows to set up sending parameters in config file & you won't have to pass them every time you want to build & send email.

Answer 2

Set that code as a function in a service. Functions are for that.
To create a service see the link below.
How to inject $_SERVER variable into a Service
Note: don't forget to inject the mail service as an argument!
arguments: ["#mailer"]
After you set your service;
public function sendMail($data)
{
$msg = \Swift_Message::newInstance()
->setSubject($data['subject'])
->setFrom($data['from'])
->setTo($data['to'])
->setBody($this->renderView($data['view']));
$this->mailer->send($msg);
}
And you can call your service like;
// this code below is just for setting the data
$data = [
'subject' => 'Hello World!',
'from' => 'from#address.com',
'to' => 'to#address.com',
'template' => 'blabla.html.twig'
];
// this code below is the actual code that will save you
$mailer = $this->get('my_mailer_service');
$mailer->sendMail($data);
