Form Builder: Frontend Validation

lorenzulrich · August 16, 2019, 8:33am

If you use the Neos Form Builder and would like to use Frontend Validation, e.g. ParsleyJS, you will have to evaluate the required/max length properties of a form element as well as the validators added to the element and then generate the according attributes (in case of ParsleyJS data-parsley- attributes.

I created a ViewHelper that might be useful as inspiration for your own validation or if you intend to use ParsleyJS, so I thought I might share it:

ElementConfigurationViewHelper.php

namespace Acme\Site\ViewHelpers\Form\FrontendValidation;

use Neos\Flow\Annotations as Flow;
use Neos\Flow\Validation\Validator\AbstractValidator;
use Neos\Flow\Validation\Validator\AlphanumericValidator;
use Neos\Flow\Validation\Validator\EmailAddressValidator;
use Neos\Flow\Validation\Validator\IntegerValidator;
use Neos\Flow\Validation\Validator\NotEmptyValidator;
