In Symfony >= 2.3, you can get the value of single fields with:

$var = $form->get('yourformfieldname')->getData();

On the other hand, you can use:

$data = $form->getData();

BUT this would get you two different things:

• the entity with values populated by the form, if your form have the data-class option enabled (so it's binded to an entity); this will exclude any field with the 'mapping' => false option

• otherwise, an array with all the form's fields
