How to connect AJAX submit to Twig form?

Answer 1

Javascript if there are other options, I'll be happy to hear them.

Answer 2

You describe in JavaScript sending to the controller for ajax.
Or, if the controller accepts not only ajax, you can check for XmlHttpRequest and return JSON.

$form = $this->createCreateForm($entity);
$form->handleRequest($request);

if ($form->isValid()) {
    $em->persist($entity);
    $em->flush();

    if ($request->isXmlHttpRequest()) {
        return new JsonResponse([
            'id' => $entity->getId(),
        ]);
    }

    return $this->redirectToRoute('route');
}
