Insert same entity three times from one form - forms

Question

I'm using symfony4 and In my project I have and entity Bill and it offer two packs:
1) First pack, user can generate just one bill in PDF after filling out a form and saving data in database and it has its own price.
2) Second pack, user can generate Three bills in PDF after filling out a form and saving data in database and this has its own price also.
The first pack is simple and it works fine , I have created BillType and an action in the controller and everything is well.
public function newBillFirstPack(Request $request)
{
$entity = new Bill();
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(BillType::class, $entity);
$form->handleRequest($request);
if ($form->isSubmitted()) {
if ($form->isValid()) {
$em->persist($entity);
$em->flush();
//...............
}
}
return $this->render('frontOffice/bill/new_first_pack.html.twig', array(
'form' => $form->createView()
));
}
The problem is with the second pack , I'd like to know how can I create three bills from one form. I tried to create 3 FormType
- FirstBillType and a twig to render its view.
- SecondtBillType and a twig to render its view.
- ThirdBillType and a twig to render its view also.
And in the controller I created three forms.
I didn't test it yet but even it works I don't like it , I fell it's not a clean solution. Imagine if a day I want to edit an attribute in the formType, so I must edit it in three formsType and three html.twig views, same thing if I want to remove or add an attribute in the forms.
I have see in the documentation "How to Embed a Collection of Forms", but that example is how to embed one attribute many times.
Any good solution ?

If I understand what you need. New action can handle this and depending on your needs form can run different action.
public function newBillThirdPack(Request $request)
{
$entity = new Bill();
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(BillType::class, $entity);
$form->handleRequest($request);
if ($form->isSubmitted()) {
if ($form->isValid()) {
$em->persist($entity);
$em->persist(clone $entity);
$em->persist(clone $entity);
$em->flush();
//...............
}
}
return $this->render('frontOffice/bill/new_third_pack.html.twig', array(
'form' => $form->createView()
));
}
