allow_extra_fields
~~~~~~~~~~~~~~~~~~

.. versionadded:: 2.6
The ``allow_extra_fields`` option was introduced in Symfony 2.6.

**type**: ``boolean`` **default**: ``false``

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.
