twig how to render a twig template as a variable

I'm trying to render twig template as variable, using symfony. I have a 'sendAction' Controller, which uses the mailgun API to send emails to one or more mailing lists. Here is my code for the Controller:

public function sendAction(Request $request, Newsletter $newsletter, MailgunManager $mailgunManager)
$form = $this->createForm(SendForm::class);
$form->handleRequest($request);

$formData = array();

if ($form->isSubmitted() && $form->isValid())

$formData = $form->getData();

$mailingLists = $formData['mailingLists'];

foreach ($mailingLists as $list)

$mailgunManager->sendMail($list->getAddress(), $newsletter->getSubject(), 'test', $newsletter->getHtmlContent());

return $this->render('webapp/newsletter/sent.html.twig');


return $this->render('webapp/newsletter/send.html.twig', array(
'newsletter' => $newsletter,
'form' => $form->createView()
));

}


And here's my sendMail (mailgun) function:

public function sendMail($mailingList, $subject, $textBody, $htmlBody)

$mgClient = new Mailgun($this::APIKEY);

# Make the call to the client.
$mgClient->sendMessage($this::DOMAIN, array(
'from' => $this::SENDER,
'to' => $mailingList,
'subject' => $subject,
'text' => $textBody,
'html' => $htmlBody
));



I want my ' $newsletter->getHtmlContent()' to render template called 'newsletter.twig.html'. can anyone help me or point me in the right direction as to what I can do or Where I can find Tutorials or notes on what I am trying to do. the symfony documentation is quite vague.

newsletter.twig.html

webapp/newsletter/send.html.twig

$mailgunManager->sendMail($list->getAddress(), $newsletter->getSubject(), 'test', $this->render($newsletter->getTemplate()));

You can use getContent() chained to your render function.

getContent()

return $this->render('webapp/newsletter/send.html.twig', array(
'newsletter' => $newsletter,
'form' => $form->createView()
))->getContent();


SymfonyComponentHttpFoundationResponse

getContent()

Response

$this->render()

Simply inject an instance of SymfonyBundleFrameworkBundleTemplatingEngineInterface into your action, and you’ll be able to use Twig directly:

SymfonyBundleFrameworkBundleTemplatingEngineInterface

public function sendAction(Request $request, EngineInterface $tplEngine, Newsletter $newsletter, MailgunManager $mailgunManager)

// ... other code
$html = $tplEngine->render('webapp/newsletter/send.html.twig', [
'newsletter' => $newsletter,
'form' => $form->createView()
]);



Note that $this->render() (in the controller action) will return an instance of SymfonyComponentHttpFoundationResponse, while $tplEngine->render() returns a HTML string.

$this->render()

SymfonyComponentHttpFoundationResponse

$tplEngine->render()

render
