Only output form elements when filled in

While I’ve been working on a somewhat more complex form, I’ve come across the point where I’ve got a somewhat big sign up form for a dentist, where multiple people have to be able to sign up at once (a family). That’s no problem of course, but the (email) output generated by eForm does get fairly ugly, especially when only one or two people sign up, still the three of four empty name/birthday/sex forms will be mailed.

So far I haven’t quite found a way to add some extra intelligence into the form here, and I’m a bit scared away by the many files eForm uses, making it harder to hack in extra functionality. So my question would be, is this possible, already done, or how should I approach this?

Thanks in advance

Make your mail template very basic, then use an external function to add as many fields to it as there are POST values at the eFormOnBeforeMailSent event.

There’s a wiki article on how to do that here.

Thanks Susan, that’s a handy link to bookmark.

Thanks indeed, I’ll take a look at that.
