In one page, inside a form, you can have a hidden field of the form <input type="hidden" name="thing" value="$thing"> and the script invoked by the form then gets the value by using param (using CGI.pm, of course), i.e. $thing=param('thing') You can use CGI.pm to produce the code for the hidden field using something like print hidden(-name=>"thing1",-value=>"thing2"); but I seem to recall having difficulty getting variables to interpolate in the value, so I've usually used the explicit first way. (If someone can comment on the interpolation problem, I'd be happy to hear about that...) The CGI module has built-in handling of "stickiness" (i.e. maintaining state (and I believe this makes use of hidden fields in a clever way... I don't understand it very well)) but it usually takes me such a lot of messing around to get it to work properly that I mostly just use hidden fields myself. That's not meant to detract from CGI.pm at all - it is a wonderful tool, I just don't know it well enough. (I always use CGI.pm, I just don't always use all of the subtleties available.)
