Re: if statment

below is what I have currently <?php if ($HTTP_GET_VARS["id"] == "") { ?> its empty <?php }?> Now when I change the == to <> I receive the following error: Notice: Undefined index: id in c:\inetpub\wwwroot\_\users.php on line 103 Why would that not work - In asp it does, but I can't get it workin in php. If that doesn't make sense, I would like to have an if statement the says, if HTTP_GET_VARS["id"] is NOT empty then show something else Thanks for you guy's help and time -- Tim Haskins "Tim Haskins" <tim@copiousdg.com> wrote in message news:20030331201648.85534.qmail@pb1.pair.com... > Wow, that's weird- I had just tried it and that didn't work, so I thought it > might be some special php thing goin on- thanks for your help! > > -- > Tim Haskins > > > > "Jennifer Goodie" <goodie@apollointeractive.com> wrote in message > > news:NEBBIJJIKBGCCCNKMPBCMEIIGNAA.goodie@apollointeractive.com... > > so change it to "" > > > > -----Original Message----- > > From: Tim Haskins [mailto:tim@copiousdg.com] > > Sent: Monday, March 31, 2003 12:12 PM > > To: php-general@lists.php.net > > Subject: Re: [PHP] if statment > > > > > > My bad, I actually meant that the "nothing" was like, if the pr_ID in the > > url is empty then show the following text. > > > > -- > > Tim Haskins > > > > "Jennifer Goodie" <goodie@apollointeractive.com> wrote in message > > > > news:NEBBIJJIKBGCCCNKMPBCCEIGGNAA.goodie@apollointeractive.com... > > > > > > if( $HTTP_GET_VARS["pr_ID"] == "nothing"){ > > > echo "there are no products"; > > > } > > > http://www.php.net/manual/en/control-structures.php > > > > > > http://www.php.net/manual/en/ > > > > > > -----Original Message----- > > > From: Tim Haskins [mailto:tim@copiousdg.com] > > > Sent: Monday, March 31, 2003 11:56 AM > > > To: php-general@lists.php.net > > > Subject: [PHP] if statment > > > > > > > > > I'm used to asp and not php, but what would the code be for and if > > statement > > > that was like: > > > > > > if $HTTP_GET_VARS["pr_ID"] = "nothing" then > > > "there are no products" > > > end if > > > > > > Also does anyone know a great resource that lists different examples of > > php > > > variables, if statements, and so on? > > > > > > Thanks so much! > > > -- > > > Tim Haskins > > > > > > > > > > > > > > > > > -- > > PHP General Mailing List (http://www.php.net/) > > To unsubscribe, visit: http://www.php.net/unsub.php > > > >
