SilverStripe\Forms\Validation

CompositeValidator can contain between 0 and many different types of Validators. Each Validator is itself still responsible for Validating its form and generating its ValidationResult.

Required Fields allows you to set which fields need to be present before submitting the form. Submit an array of arguments or each field as a separate argument.

This validation class handles all form and custom form validation through the use of Required fields. It relies on javascript for client-side validation, and marking fields after server-side validation. It acts as a visitor to individual form fields.
