Symfony - controller edit action - php

Question

I defined the form in my controller and set function to edit/update specific fields that I can find by ID. I can't find what am I doing wrong..
public function getUserEdit(Request $request)
{
$form = $this->createFormBuilder()
->add('firstName', TextType::class, array('label' => 'First Name*', 'attr' => ['class'=>'form-control']))
->add('save', SubmitType::class, array('label' => 'Send', 'attr' => [
'class' => 'btn btn-primary action-save'
]))
->getForm();
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$data = $form->getData();
$firstName = $data['firstName'];
$this->container->get('user')->editUser($firstName);
}
return $this->success();
}
Service
public function editUser($id)
{
$editUsers = $this->getUserRepository()->find($id);
if(empty($editUsers)) {
$editUsers = new User();
$editUsers->setId($id);
$this->em->persist($editUsers);
$this->em->flush();
}
}

Symfony returns a single object when searching by find primary key (usually id), then you can check if exist returns a single Entity (in this case User) and so that checking by using insteance.
public function editUser($id)
{
$editUsers = $this->getUserRepository()->find($id);
if($editUsers insteance User) { // here just check
//$editUsers = new User(); // here You don't need create new object of class User, just remove
$editUsers->setId($id);
$this->em->persist($editUsers);
$this->em->flush();
}
else {
// do something if you need
}
}
