How do I add an unbound field to a form in Symfony which is otherwise bound to an entity?
Solution 1
In your form add a text field with a false property_path:
$builder->add('extra', 'text', array('property_path' => false));
You can then access the data in your controller:
$extra = $form->get('extra')->getData();
UPDATE
The new way since Symfony 2.1 is to use the mapped
option and set that to false
.
->add('extra', null, array('mapped' => false))

Solution 2
Since Symfony 2.1, use the mapped
option:
$builder->add('extra', 'text', [
'mapped' => false,
]);
Solution 3
According to the Documentation:
allow_extra_fields
Usually, if you submit extra fields that aren't configured in your form, you'll get a "This form should not contain extra fields." validation error.
You can silence this validation error by enabling the
allow_extra_fields
option on the form.
mapped
If you wish the field to be ignored when reading or writing to the object, you can set the
mapped
option to false.
class YourOwnFormType extends AbstractType
{
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
array(
'allow_extra_fields' => true
)
);
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$form = $builder
->add('extra', TextType::class, array(
'label' => 'Extra field'
'mapped' => false
))
;
return $form;
}
}

Maybe I'm missing the obvious but how do I (or can I) add an extra "unbound" field to a Symfony form that is otherwise bound to an entity?
Let's say I have an entity with fields
first_name
andlast_name
. I do the typical thing in my form classbuildForm
method.$builder ->add('first_name') ->add('last_name') ;
and this in my controller:
$editForm = $this->createForm(new MyType(), $entity);
That works nicely but I'd like to add another text box, let's call it "extra", and receive the value in the POST action. If I do
$builder->add('extra')
, it complains thatNoSuchPropertyException in PropertyAccessor.php line 479:
Neither the property "extra" nor one of the methods "getExtra()", "extra()", "isExtra()", "hasExtra()", "__get()" exist and have public access in class...
Which is correct. I just want to use it to collect some extra info from the user and do something with it other than storing it with the entity.
I know how to make a completely standalone form but not one that's "mixed". Is this possible?
