Handling a complex Symfony2 form with multiple entities relationship - php

Question

I have a form (still not finished and is missing many fields) that is handled as a wizard with steps, in which fields from multiple entities are handled. This is the form itself:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('tipo_tramite', 'entity', array(
'class' => 'ComunBundle:TipoTramite',
'property' => 'nombre',
'required' => TRUE,
'label' => "Tipo de Trámite",
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('q')
->where('q.activo = :valorActivo')
->setParameter('valorActivo', TRUE);
}
))
->add('oficina_regional', 'entity', array(
'class' => 'ComunBundle:OficinaRegional',
'property' => 'nombre',
'required' => TRUE,
'label' => "Oficina Regional",
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('q')
->where('q.activo = :valorActivo')
->setParameter('valorActivo', TRUE);
}
))
->add('procedencia_producto', 'entity', array(
'class' => 'ComunBundle:ProcedenciaProducto',
'property' => 'nombre',
'required' => TRUE,
'label' => "Procedencia del Producto"
))
->add('finalidad_producto', 'entity', array(
'class' => 'ComunBundle:FinalidadProducto',
'property' => 'nombre',
'required' => TRUE,
'label' => "Finalidad del Producto"
))
->add('condicion_producto', 'entity', array(
'class' => 'ComunBundle:CondicionProducto',
'property' => 'nombre',
'required' => TRUE,
'label' => "Condición del Producto"
))
->add('lote', 'integer', array(
'required' => TRUE,
'label' => "Tamaño del Lote"
))
->add('observaciones', 'text', array(
'required' => FALSE,
'label' => "Observaciones"
));
}
I have a question regarding how to handle the parameter data_class in this case so I do not have to do magic in the controller. When I say magic I mean the following:
public function empresaAction()
{
$entity = new Empresa();
$form = $this->createForm(new EmpresaFormType(), $entity);
return array( 'entity' => $entity, 'form' => $form->createView() );
}
public function guardarEmpresaAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
/** #var $userManager \FOS\UserBundle\Model\UserManagerInterface */
$userManager = $this->container->get('fos_user.user_manager');
/** #var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
$dispatcher = $this->container->get('event_dispatcher');
/** #var $mailer FOS\UserBundle\Mailer\MailerInterface */
$mailer = $this->container->get('fos_user.mailer');
$request_empresa = $request->get('empresa');
$request_sucursal = $request->get('sucursal');
$request_chkRif = $request->get('chkRif');
$request_estado = $request_empresa[ 'estado' ];
$request_municipio = $request->get('municipio');
$request_ciudad = $request->get('ciudad');
$request_parroquia = $request->get('parroquia');
$user = $userManager->createUser();
$event = new GetResponseUserEvent($user, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_INITIALIZE, $event);
if (null !== $event->getResponse())
{
return $event->getResponse();
}
$entity = new Empresa();
$form = $this->createForm(new EmpresaFormType(), $entity);
$form->handleRequest($request);
$success = $url = $errors = "";
if ($form->isValid())
{
if ($request_sucursal != NULL || $request_sucursal != "")
{
$padreEntity = $em->getRepository('UsuarioBundle:Empresa')->findOneBy(array( "padre" => $request_sucursal ));
if (!$padreEntity)
{
$padreEntity = $em->getRepository('UsuarioBundle:Empresa')->findOneBy(array( "id" => $request_sucursal ));
}
if ($request_chkRif != NULL || $request_chkRif != "")
{
$rifUsuario = $request_empresa[ 'tipo_identificacion' ] . $request_empresa[ 'rif' ];
}
else
{
$originalRif = $padreEntity->getRif();
$sliceRif = substr($originalRif, 10, 1);
$rifUsuario = $originalRif . ($sliceRif === false ? 1 : $sliceRif + 1);
}
$entity->setPadre($padreEntity);
}
else
{
$rifUsuario = $request_empresa[ 'tipo_identificacion' ] . $request_empresa[ 'rif' ];
}
$user->setUsername($rifUsuario);
$user->setRepresentativeName($request_empresa[ 'razon_social' ]);
$user->setEmail($request_empresa[ 'usuario' ][ 'email' ]);
$user->setPlainPassword($request_empresa[ 'usuario' ][ 'plainPassword' ][ 'first' ]);
$pais = $em->getRepository('ComunBundle:Pais')->findOneBy(array( "id" => 23 ));
$user->setPais($pais);
$estado_id = $request_estado ? $request_estado : 0;
$estado = $em->getRepository('ComunBundle:Estado')->findOneBy(array( "id" => $estado_id ));
$user->setEstado($estado);
$municipio_id = $request_municipio ? $request_municipio : 0;
$municipio = $em->getRepository('ComunBundle:Municipio')->findOneBy(array( "id" => $municipio_id ));
$user->setMunicipio($municipio);
$ciudad_id = $request_ciudad ? $request_ciudad : 0;
$ciudad = $em->getRepository('ComunBundle:Ciudad')->findOneBy(array( "id" => $ciudad_id ));
$user->setCiudad($ciudad);
$parroquia_id = $request_parroquia ? $request_parroquia : 0;
$parroquia = $em->getRepository('ComunBundle:Parroquia')->findOneBy(array( "id" => $parroquia_id ));
$user->setParroquia($parroquia);
...
}
else
{
$errors = $this->getFormErrors($form);
$success = FALSE;
}
return new JsonResponse(array( 'success' => $success, 'errors' => $errors, 'redirect_to' => $url ));
}
Since the 'data_classonEmpresaFormTypeis set toUsuarioBundle\Entity\Empresa` then I need to handle any extra parameter as example above show with getter/setter and that's a lot of work for complex/big forms.
In the sample form, the fields tipo_tramite will persist in the class ComunBundle\Entity\Producto but the field oficina_regional will persist in the class ComunBundle\Entity\SolicitudUsuario and so with others who are not placed even here but they are in the form, in total should persist as 3 or 4 entities including relationships in many cases, how do you handle this?
I know there is CraueFormFlowBundle that maybe cover this process/flow but not sure if it is the solution to go.
Any advice?

Answer 1

Just worked with multi-step form few days ago. I think you need embedded forms here. Anyway can suggest you another nice bundle for creating wizard: SyliusFlowBundle. IMO it's more flexible and easier to understand than CraueFormFlowBundle.
BTW why do you want to store all in one form? We've used one form for each step, and I liked this approach.
