Re: i need help with an undefined variable

You should test first for the existence of the var before using it... a better code would be: <?php @include("head.html"); if (!isset($_GET["game"])) { @include("public.html"); } ?> You should test for the existence of the var instead of using it's value in a condition... otherwise you will get a warning for each that you use without a previous definition... Cheers... Luis Ferro <?php

include("head.html");

if (isset()

if (!$_GET["game"]) { include("public.html"); } if ($_GET["game"] != NULL && $op != NULL) { include("http://mywebsite.com/example/" . "$game" . ".html"); }

have u tried using $_GET["game"] or $_POST["game"] ? so your code is <?php

include("head.html"); if (!$_GET["game"]) { include("public.html"); } if ($_GET["game"] != NULL && $op != NULL) { include("http://mywebsite.com/example/" . "$game" . ".html"); }

or post instead of get in there?

-----Original Message----- From: Anyang [mailto:anyang@optonline.net] Sent: Wednesday, 2 October 2002 11:38 AM To: php-windows@lists.php.net Subject: [PHP-WIN] 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. -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
