Hi all,
I am just preparing some registration form for conference participants by using FormItBuilder v1.3.3. Now I need to add some auto computed field (sum of selected prices) according to selected choices (prices for food, conference fee, etc.) - similar to basket total price in eshop.
Is it possible to do it by using FormItBuilder?

Thanks

Hi monami,
FormItBuilder will create a base form for you quite fine, but any unique logic can still be added on top using a combination of jQuery validate (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) as well as a more secure additional posthook. You can essentailly get your post hook to do whatever you like.

Obviously some knowlege in jQuery and and PHP are kind of required, but this link below should get you started.
