What would be the best way from your point of view to add additional validations for custom fields to the booking form to stay aligned with your plugin updates?
- if custom field 1 is filled, custom field2 will be required (add error msg)
- Depending on the service selection, custom fields should be displayed/hidden/required
- depending on the input of custom field1, input of custom field2 must be validated against a list of criteria
Thanks for your advice!
