I always pass a hidden form element that is a counter filled in by JS for how many fields have been added. So if I have a field named foo_1 and I add foo_2, foo3, foo_4 and take away even foo_2 my hidden counter will pass in 4. then on the processing side I do a loop over my counter, something like:
<cfloop from="1" to="#Form.Counter#" index="i"> <cfif StructKeyExists(FORM, "foo_#i#") AND Trim(Form["Foo_#i#"]) IS NOT "">Then do something</cfif> </cfloop> On Fri, Dec 19, 2008 at 2:02 PM, Judah McAuley <[email protected]> wrote: > The way I do this is to have each form field have an underscore in it. > So play_1, play_2, etc > > Then I'd loop over the FORM collection and do a listfirst with _ as a > delimiter to figure out if I've got a play, a po, a role, etc or some > random field (like submit) that I don't care about.
