RE: i need help with an undefined variable

this is due to 'register_globals' is off by default in php 4. this is for security reasons. pls. use $game as $_GET['game']. alternatively you can turn on 'register_globals' in php.ini (not recommended). regds, -----Original Message----- From: Anyang [mailto:anyang@optonline.net] Sent: Wednesday, October 02, 2002 07:08 To: php-windows@lists.php.net Subject: i need help with an undefined variable I wrote a php script for a page that I hosted on a separate host and it worked perfectly. I recently installed php 4 onto my windows XP Pro build 2600 computer and it seems to work until I try to use varuables that look to the address bar for reference. I wanted to make it so that when somebody clicks "game" it would go to www.mywebsite.com/index.php?game=example and that would merely replace the body with the example page. It worked on my other host but when I tried it on my computer it says: Notice: Undefined variable: game in C:\Xitami\webpages\index.php on line 5 Notice: Undefined variable: game in C:\Xitami\webpages\index.php on line 8 My script says: <?php include("head.html"); if (!$game) { include("public.html"); } if ($game != NULL && $op != NULL) { include("http://mywebsite.com/example/" . "$game" . ".html"); } any ideas? please help. if there's any script i can type and have all the pages require it so that this can be defined that would work great.
