Re: CGI form 'falls through' without capturing anything

What part of the code implements "get the user's response"? Do you understand how HTTP and CGI work?

The CGI code runs on the server and generates the page, the client (a browser) interprets that and shows it to a user. Running a subroutine on a server doesn't wait for user input. You need a different page for the Captcha, or implement it in JavaScript.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

This really is the key, of course. I didn't. When I started work on this I thought 'as long as I don't try to do anything the rest of the program isn't trying to do, I'll be okay', but that has turned out not to be the case at all.

I queried a much more experienced friend on this and now have a better understanding of CGI; however, I am now uncertain how to solve the problem at all.

I can make the desired 'captcha' image display correctly on the first of a number of screens. However, I don't know how to have the generated captcha object 'persist' to a 'place' where I can run the check of the user's guess against it: I can't shove it into a hidden field -- or at least I don't know how to correctly. So after the user hits submit on that first screen, I have the user's input in a parameter, but the generated captcha object is gone.

I'd write more but I'm practicing succinctness. :)

UPDATE: problem solved. It was a stupid problem, having nothing to do with making objects persist -- but everything to do with making my cool headspace persist so I don't miss stupid things. Thanks!!
