Class constraint validator in form type class?

Question

In the documentation it lists examples for applying a class validation constraint to Annotations, XML and YAML but not for PHP.

Since the validation is not applied to a property, where do I add this class validation constraint to the whole class inside a Symfony form type?

Answer 1

I think I've found a solution here: https://knpuniversity.com/screencast/question-answer-day/custom-validation-property-path There is a tip what says:

If your form lives in a form type class, simply add the constraints key to the setDefaulOptions method.

Answer 2

I couldn't find the setDefaultOptions mentioned on the other answer, but managed to get it to work with OptionsResolver::setDefaults. It must have something to do with Symfony's version.

Something like this should do the trick:

$resolver->setDefaults([
        'constraints' => [
            // list of constraints,
        ],
    ]);
