How to Disable the Validation of Submitted Data

.. versionadded:: 2.3
    The ability to set ``validation_groups`` to false was introduced in Symfony 2.3.

Sometimes it is useful to suppress the validation of a form altogether. For these cases you can set the validation_groups option to false:

use Symfony\Component\OptionsResolver\OptionsResolver;

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'validation_groups' => false,
    ));
}

Note that when you do that, the form will still run basic integrity checks, for example whether an uploaded file was too large or whether non-existing fields were submitted.

The submission of extra form fields can be controlled with the :ref:`allow_extra_fields config option <form-option-allow-extra-fields>` and the maximum upload file size should be handled via your PHP and web server configuration.
