使用createFormBuilder（）预填充symfony2表单

Question

Here is my form:

$studentObj = $this->getDoctrine()->getRepository('ProjectEntityBundle:Student')
                    ->findBy(array('user' => $userId));
    $form = $this->createFormBuilder($studentObj)
            ->add('fname', 'text', array('label' => 'First Name'))
            ->add('lname', 'text', array('label' => 'Last Name'))
            ->add('save', 'submit', array('label' => 'Save My Profile'))
            ->getForm();

I pass $userId from route variable. But it does not pre fill the data. How do I solve the issue?

Answer 1

You have to do the "prefill" at controller "level".

Say that you have an editStudentController and that your form is named studentFormType you will do

public function editStudentController() {
  //retrieve here $userId;
  $student = $this->getDoctrine()->getRepository('ProjectEntityBundle:Student')
                                     ->findOneBy(array('user'=>$userId));
  $form = $this->createForm(new studentFormType(), $student);
  [...]
  $view = $form->createView();
  [...]
}
