Defining cross-field validation in a form
Cross-field Validation is used to validate multiple fields in a form if their values are correlative.
For example, on most account registration forms, there are two password inputting fields. In order to avoid customers inputting wrong password accidentally, both fields must have the same value before the form can be submitted.
