Pre Fill Symfony Form Text Field with Data From the Database

Question

How can I pre fill a text field in symfony with data from the database. I have a field in the host table called hostFee and when I create the form I want that data to pre fill this text field.

I am creating a form for new BookingSpecsType()...

Here is my form builder element.

$builder->add('hostFee', 'text', array(
        'required'=>false,
        'error_bubbling'=>true,
        'label'=>'Do you charge a hosting fee?',
        'data' => '??????? (How do I fill this text field dynamically with the Host table hostFee column data) ?????',
        'attr'=>array(
            'placeholder'=>'If yes, enter dollar amount $0.00',
            'class'=>'form-control'
        )
    ));

Thanks.

The documentation provide many examples.

When you use $this->createForm in your Controller action, the second parameter, allow you to hydrate the form with an object.

For example:

public function editAction()
{
        $user = $this->getDoctrine()->getRepository('User')->find(1); // YOUR OBJECT RETRIEVED FROM THE DB FOR EXAMPLE
        $form = $this->createForm(new EditType(), $user, array(
            'action' => $this->generateUrl('account_edit'),
        ));

        return $this->render(
            'AcmeAccountBundle:Account:edit.html.twig',
            array('form' => $form->createView())
        );
}

You do not need to define manally the data. If you just init the form from an hydrated entity, then all data are init into all fields.
