By default, the signup url for ver. 4+ is in this format /signup/index/c/1 I would like to change the signup url that includes the ID number. Here is one example site with the signup url: http://www.wpzoom.com/purchase/?id=119 May I know how to do it?
You already can load signup form such way : /signup/index?c=1 c is signup form code which you set in forms editor. if you want to change variable name from "c" to "ID" create own custom Rewrite Rules which were redirect user from urls like: /purchase/?id=119 to /signup/index/c/119
