表单提交后如何设置数据？

Question

这是以下问题Symfony 2.7. How to get/set value of the Form field after Form submission?的扩展。

在表单提交后，我需要在控制器中设置表单字段的数据。此功能不起作用。如何启用？如何通过其他方式实现这一点？

...\src\MeetingBundle\Form\EventType.php

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('starttimeInt', 'hidden', array('data' => '0',) )
        ->add('endtimeInt', 'hidden', array('data' => '0',) ) 

..\src\MeetingBundle\Controller\EventMapController.php

$starttimeInt=$dateObj->getTimestamp();
$form->get('starttimeInt')->setData($starttimeInt); 
$starttimeIntSet=$form->get('starttimeInt')->getData();
print_r($starttimeIntSet); // prints 0 instead of the timestamp

$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush(); // starttimeInt column contains 0 instead of timestamp, which i want to add to the form after form submission

Answer 1

答案是将数据设置为实体：

..\src\MeetingBundle\Controller\EventMapController.php

/**
 * Creates a new Event entity.
 *
 * @Route("/createjsmapV2", name="ev_jsMap_createV2")
 * @Method("POST|GET")
 * @Template("MeetingBundle:event:ev_jsMap_new.html.twig")
 */
public function createJsMapAction(Request $request)

    $entity = new Event();
    $form = $this->createCreateJsMapForm($entity);
    $form->handleRequest($request);
if ($form->isValid()) {
    $starttimeInt=$dateObj->getTimestamp();
// form->get('starttimeInt')->setData($starttimeInt); // this will not work, you will find 0 in the database as it is the default value in FormType

//here you can set the data to any field you want to modify, after the user submitted the form
    $entity->setStarttimeInt($starttimeInt);
    $em = $this->getDoctrine()->getManager();
    $em->persist($entity);
    $em->flush();
