How to add additional non-entity fields to entity form in Symfony2

Question

I have created form with one element from Entity:

$promo = new Promo();

$form = $this->createFormBuilder($promo)
        ->add('code', 'text')
        ->getForm();

And I want to add file element (this field doesn't exist in the Entity). When I do:

$form = $this->createFormBuilder($promo)
        ->add('code', 'text')
        ->add('image', 'file')
        ->getForm();

I have an error: Neither property "image" nor method "getImage()". How can I add this field?

Use mapped:

$form = $this->createFormBuilder($promo)
    ->add('code', 'text')
    ->add('image', 'file', array(
                "mapped" => false,
            ))
    ->getForm();

In old Symfony versions (2.0 and earlier), use property_path:

$form = $this->createFormBuilder($promo)
    ->add('code', 'text')
    ->add('image', 'file', array(
                "property_path" => false,
            ))
    ->getForm();

"property_path" was removed in Symfony 2.3

Cool. Didn't know about the mapped option.

Thanks. I will use property_path = false.

Use the property_path option:

$builder->add('image', 'file', [
    'property_path' => false,
]);

This is removed since Symfony 2.3. The new way is to use mapped like in the new correct answer.
