Question

I want to generate a class-less form inside my service.

The way I do it is:

class StepSummary implements StepInterface 
{
    public function __construct($container)
    {
        $this->container = $container;
    }

    public function getVariables()
    {
        $form = $this->container->get('form.factory')->createBuilder('text')
            ->add('accept')
            ->getForm();

        return array('form' => $form->createView());
    }
}

In the API, I’ve found that I need to pass a form type to the FormBuilder – I didn’t find any reference to that, so I’ve put imaginary text string. Now it renders the form but this way:

<input type="text" id="text" name="text" required="required" />

Obviously there is no reference to the accept field.

Answer 1

Controller’s createForm() method was quite helpful here:

    public function createFormBuilder($data = null, array $options = array())
    {
        return $this->container->get('form.factory')->createBuilder('form', $data, $options);
    }

So the solution is:

$form = $this->container->get('form.factory')->createBuilder('form')
            ->add('accept')
            ->getForm();
