How to do edit function in symfony2 - php

Question

I have written a function for edit in symfony2, my problem is i can fetch the previous values from the database but after submitting the form the values were notr created instead a new form is creating
Here is the controller
public function editAction($id){
$request = $this->getRequest();
$em = $this->getDoctrine()->getEntityManager();
$profile= $em->getRepository('TcprofileBundle:TcProfiles')
->find($id);
$profile_form = $this->createForm(new ProfileType(), $profile);
$response = new JsonResponse();
$response->setData(array('content' => $this->renderView('TcprofileBundle:Default:create.html.twig',array('form' => $profile_form->createView()))));
return $response;
}
Html.twig file
<div class="edit01"> Edit Profile </div>
I'm fetching the old values, so i put if loop for condition check like this
controller
public function editAction($id){
$request = $this->getRequest();
$em = $this->getDoctrine()->getEntityManager();
$profile= $em->getRepository('TcprofileBundle:TcProfiles')
->find($id);
if(!$id){
$profile_form = $this->createForm(new ProfileType(), $profile);
$response = new JsonResponse();
$response->setData(array('content' => $this->renderView('TcprofileBundle:Default:create.html.twig',array('form' => $profile_form->createView()))));
return $response;
}else{
$profile->upload();
$em->persist($profile);
$em->flush();
$response = new JsonResponse();
$response->setData(array('content' => $this->renderView('TcprofileBundle:Default:create.html.twig',array('form' => $profile_form->createView()))));
return $response;
}
}

You can use $em->merge($profile) instead of $em->persist($profile) when updating an entity. Please this stack overflow post
