Question

i want to edit my data with symfony form and i have a problem
probably with my controller. I have some like this :
public function detailAction($id,Request $request)
{
$order = $this->getDoctrine()->getRepository(OrderMain::class)->find($id);
if (!$order) {
throw $this->notFoundException();
}
$form = $this->createForm(OrderMainType::class, $order);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// do not enter here
$orderEdit = $form-getData();
$em = $this->getDoctrine()->getManager();
$em->persist($orderEdit);
$em->flush();
}
return $this->render('ModiModiAdminBundle:Order:detail.html.twig',array(
'form' => $form->createView(),
));
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
/.../
->add('edit', SubmitType::class, array(
'attr' =>array('class'=>'edit'),
));
}
All show corectly but when i click a button my page is reload ( dosen't save changes ). Thanks for help.

Answer 1

It is an issue with your controller method. Below should work for you.
public function detailAction($id,Request $request)
{
$order = $this->getDoctrine()->getRepository(OrderMain::class)->find($id);
if (!$order) {
throw $this->notFoundException();
}
$form = $this->createForm(OrderMainType::class, $order);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
//do not enter here
$em = $this->getDoctrine()->getManager();
$em->flush();
}
return $this->render('ModiModiAdminBundle:Order:detail.html.twig',array(
'form' => $form->createView(),
));
}
You can remove the line of $orderEdit = $form-getData();. When your form is submitted, the entity should be updated based on the submitted data. Since this is already a managed entity, you can also remove $em->persist($orderEdit);

Answer 2

public function edit(Request $request)
{
$id = $request->get('id');
$category = $this->getDoctrine()->getRepository(Category::class)->find($id);
if (!$category) {
throw $this->notFoundException();
}
$form = $this->createForm(CategoryType::class,$category);
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()){
$em = $this->getDoctrine()->getManager();
$categoryData = $form->getData();
$em->persist($categoryData);
$em->flush();
}
return $this->render('admin/category/edit.html.twig',array(
'form' => $form->createView(),
));
}
you are missing => handle request from code
$form->handleRequest($request);
