How to Define the Validation Groups to Use

Validation Groups

If your object takes advantage of :doc:`validation groups </validation/groups>`, you'll need to specify which validation group(s) your form should use. Pass this as an option when :ref:`creating forms in controllers <creating-forms-in-controllers>`:

$form = $this->createFormBuilder($user, [
    'validation_groups' => ['registration'],
])->add(...);

When :ref:`creating forms in classes <creating-forms-in-classes>`, add the following to the configureOptions() method:

use Symfony\Component\OptionsResolver\OptionsResolver;

public function configureOptions(OptionsResolver $resolver): void
{
    $resolver->setDefaults([
        // ...
        'validation_groups' => ['registration'],
    ]);
}

In both of these cases, only the registration validation group will be used to validate the underlying object. To apply the registration group and all constraints that are not in a group, use:

'validation_groups' => ['Default', 'registration']

Note

You can choose any name for your validation groups, but Symfony recommends using "lower snake case" names (e.g. foo_bar) in contrast with the automatic validation groups created by Symfony, which use "upper camel case" (e.g. Default, SomeClassName).
