Question

So I have read that I can set the default value of a field in symfony2 formbuilder by doing this

->add('myfield', 'text', array(
  'label' => 'Field',
  'data' => 'Default value'
))

Now I want to manipulate the value that would be here by default, in order to know what to set, I need to know what was originally passed, so can I get the default value like

myfield.default_value

so that i can later manipulate it and set the result of my manipulation as the real default value?

Addition:
I tried

    ->add('username', 'text', array('label' => 'Användarnamn ', 'data' => 'my_own_defaultvalue'))

That didn’t work for me (seen it in a bunch of forums though…).

Then I realized that probably the easiest way is to just edit the object before I pass it to the formBuilder, like this:

public function editUserAction($id)
{   

    $em = $this->getDoctrine()->getEntityManager();

    $entity = $em->getRepository('BizTVUserBundle:User')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find Container entity.');
    }

      //run some action to modify one of the variables of $entity

    $entity->setUsername($username_stripped); //put my edited variable into the object, now we're ready to pass my new and improved $entity to the formBuilder...

    $editForm = $this->createForm(new editUserType(), $entity);

    return $this->render('BizTVUserBundle:Default:editUser.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
    ));
}
