Hi,
I am looking for the following functionality:
The user is required to fill in either one of two fields to be able to submit. (e.g. There is a phone number field and an email field and the user must fill in at least 1 to leaves some sort of contact details.)
Is this possible with Gravity Forms?
Many thanks!
This isn't a built in feature. A field is either required or it is not required. There are no options for either or functionality as far as required fields go. It would be possible to do this, but only as a customization using the gform_validation API hook You'd have to write your own custom validation. We have a tutorial on how to use the gform_validation hook here:
http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_valiation%22_Hook
I usually handle this with a conditional "How would you like to be contacted?" question, with two multiple choice (radio button) options: phone and email.
Then you show the phone field if they selected "phone" and the email field if they selected "email" using the built in "conditional logic" feature. Make both the phone and email fields required. Gravity Forms is smart enough to know that a conditional field that is required but unused (i.e. they want to be contacted by phone, so the email field is not used) does not fail validation. It won't be required any longer.
Here's a quick example:

I'm certain there are other ways to handle it, but this is one simple way. I realize this is a pre-sales question, but rest assured that what you want to achieve is certainly possible with Gravity Forms.
I'm also interested in this.
The example at http://guitar.chrishajer.com/2011/07/08/conditional-contact-form/ is a little bit wonky, though -- if you click Phone and then decide you prefer Email, it won't switch. If you click Email first, then Phone, you get both. Is this default behavior, or would there be a way to clean up the functionality so it would switch if you change your mind on the fly?
The problem with dredging up old posts is that sometimes they no longer work :-)
I updated my Gravity Forms and WordPress installation there and you will see now that it works.
You're welcome. Good luck to you.
