Re: Passing variable from webpage to php (newbie?)

You have register_globals set to off (read up on "register globals" in php.net). your code should read $HTTP_POST_VARS['action'] or $_POST['action'] (depending on PHP version) INSTEAD of just $action. so to test an if:: if ($HTTP_POST_VARS['action']==1) { /* Code for if action is equal to 1 */ } Of course checkingif the variable is set or empty might be a good idea as well, is set example: if (isset($HTTP_POST_VARS['action'])) { /* Code if the variable POSTed is set */ } "Joe Kupiszewski" <joe@thekups.com> wrote in message news:20030319155813.42156.qmail@pb1.pair.com... > I think I already tried to post once, so sorry if this is a duplicate, but I > don't see my first attempt.
