OK well lemme try again :)

If no javascript, then don't you have to make a trip back to the webserver everytime the user adds a field? In that case you can just number them as you create them and there's no need for an array, you just have a lot of parameters.

The PHP thing looks slick, but it's really just a convenience method. CGI.pm has convenience methods too, check out "FETCHING THE PARAMETER LIST AS A HASH" in the CGI.pm docs. Seems like kinda the same thing.
