How to Disable the Validation of Submitted Data

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): void
{
    $resolver->setDefaults([
        '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 allow_extra_fields config option and the maximum upload file size should be handled via your PHP and web server configuration.
