Re: Variable Problem when UPGRADING...

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 ($var == '') { regards, philip olson http://www.cornado.com/ On Mon, 29 Jan 2001, James Smith wrote: > Alright, when i was programming with PHP3, I would use > if statements like this: > > if(!$submit) { > // display form > } else { > // display signup complete > } > > to make multiple pages.
