Conditional Validation: Both cannot be blank

[yogastudents362523]

I want Validation Toolkit to insist that I receive either a cell phone number or a land number from my form. One of ['cellphone'] OR ['contactphone'] is required, but both can be provided if desired.

Suppose my error message is "NO". What coding must surround "NO" so Validation Toolkit does what I want and shows "NO" if both phone number fields on my form are left blank?

Please keep this very very simple! I am learning fast ... but I am obviously still a newbie. I've tried experimenting with:
!isset($_POST['contactphone']?!$_POST['cellphone']:"NO" but it's not working out. Either I have that wrong, or I am inserting it in the wrong place.

Thanks.

OK. I think I solved my own problem.
I will create a third, hidden field.
I will then arrange for it to be filled, conditinally, with either one or the other of my two phone fields.

I will then validate that third field. It will be required, and may not be blank. I believe that will work.
Thanks.

That sounds like it will work for this purpose. Make sure to put the code that populates the hidden field before the code that validates the hidden field.
