Note Submitter: timeblind@crucial-systems.com ---- This is a touch buried in the docs. If you need to iterate over form submitted fields (and you don't always know what they are going to be): If PHP's track_vars feature is turned on, either by the track_vars configuration setting or the <?php_track_vars?> directive, then variables submitted via the POST or GET methods will also be found in the global associative arrays $HTTP_POST_VARS and $HTTP_GET_VARS as appropriate.
