$em = $this->get('doctrine')->getManager();
/** #var Product $product */
$product = $em->getRepository(Product::class)->find($productId);
$comment->setAuthor($this->tokenStorsge->getToken()->getUser());
$comment->setProduct($product);
$comment->setContent($form->get('content')->getData());
$this->em->persist($comment);

From here
Doctrine 2 ORM does not support INSERT via DQL or the DQL query builder. For a complete syntax, check the EBNF of DQL.
You can add more abstractions if you want your controller to look slightly more beautiful, off the top of my head (effective in Symfony 2.8):
BaseController.php:
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
abstract class BaseController extends Controller
{
/**
* #return ProductRepository
*/
protected function getProductRepo()
{
return $this->get('doctrine.orm.entity_manager')->getRepository(Product::class);
}
}
CommentController.php:
Use native controller functions to create a form and get the currently logged in user. And if you are not intend to add more complex logic between $form->isSubmitted() and $form->isValid() use just $form->isValid()
class CommentController extends BaseController
{
public function newAction(Request $request, $productId)
{
$comment = new Comment();
$form = $this->createForm(CommentForm::class, $comment);
$form->handleRequest($request);
if ($form->isValid()) {
/** #var Product $product */
$product = $this->getProductRepo()->find($productId);
$comment->setAuthor($this->getUser());
$comment->setProduct($product);
$comment->setContent($form->get('content')->getData());
$this->em->persist($comment);
$this->em->flush();
}
return $this->render(':form:comment.html.twig', array(
'form' => $form->createView(),
));
}
}
