hi again james,
btw, consider doing this :
if (empty($submit)) {
or
if (!empty($submit)) {
as it doesn't run into such problems. or use isset although i tend to
almost always use empty, i LOVE empty() !!! each have their uses :
http://www.php.net/manual/en/function.empty.php
http://www.php.net/manual/en/function.isset.php
there are also compare functions such as :
http://www.php.net/manual/en/function.strcmp.php
but anyway, those are other options to consider. options are good. but
really for such things use empty(), also the following is bad form (imho
of course) :
if ($var == '') {
regards,
