Problem: I have two custom fields in a Form, and I would like to only allow one of the fields to be filled in. I would like to set up some form validation that prevents form submission if a User fills in values for both fields.
Solution: There are two options in our system:
- Conditional Form Groups: You can use Conditional Form Groups to show or hide the "Submit" button based on the value of these fields. If both fields are not empty, then you can hide the submit button. This is "front-end" validation, meaning that the validation occurs before the form is submitted.
- Custom validation API: You can use custom code to validate form fields on the "back-end". If errors are detected, the form will reload and display your custom error messages. This requires PHP code.
Beyond that you may be able to use custom JavaScript to handle this type of DOM manipulation.
