Question

The following (simple) question from me:

  $user = new User();
  $user->setEventid(2);
  $user->setT(new \DateTime('now'));

  $em = $this->getDoctrine()->getManager();
  $em->persist($user);
  $em->flush();

  $form = $this->createFormBuilder($user)
    ->add('email', 'email')
    ->add('terms', 'checkbox', array(
          'label'     => 'Read terms?',
          'required'  => true))
    ->getForm();

This is my code. Email is property of the user, terms not.
I want them users to save their email and check the terms-checkbox but i just need to save the email, not if they check the box – if they don’t they cant submit the form.

You know what i mean? I’m shure its pretty simple to achieve this 😉

Second Question: How can i give the rendered from-tag an id-attribute for further handeling in jquery?

Answer 1

To add a field that doesn’t exist in the entity to a form, use this:

->add('terms', 'checkbox', array(
    'label'         => 'Read terms?',
    'required'      => true,
    'mapped'        => false, // this works since Symfony 2.1
    'property_path' => false, // this works since Symfony 2.0
))

Symfony generates an ID for each form element; just open the rendered page source and see the ID of the element you need.
