Re: HTML form – make one of two fields required

“But we’ll need to have either YOUR PHONE or YOUR EMAIL required – one of these, but not both.”.

People won’t understand that, if they see two fields they’ll automatically complete them especially as they are compulsory (in effect).

If you need one of two, I’d give them an option to select their preferred choice and then reveal the necessary input.

Alternatively, make them enter both but insist on a ‘preferred’ method…it’s just coming at it from the other direction.
