Jquery form e-mail OR phone required
I'm pretty noob, and try as I may I cannot fathom how to get my form to give an error message if the telephone or email is not filled in. I only need one of them to be filled in, i.e. it's a contact form, I need to be able to respond somehow.
I can make it do an error for each individually, but not either or. I was trying to use an OR statement. || but I couldn't make it work :(
Your suggestions are invaluable.
Cheers in advance,
p.s. what is a trackback?
