Help with this show thread script

Mikchal

I have a forum, it's yamoto-studios.com/forum
Everytime I enter the thread URL up in my browser, It shows me a page that says "No thread specified". The script connects to my database successfully, but it won't show the thread. Here's the script:
<html>
<head>
<?

// gothread.php
if (!isset($threadID)) {
echo "No Thread Specified";
exit();
} else {
include('./db.php');
// Connect to database
$link = dbConnect();
//let's get the forumID from threadID
$query = "SELECT forumID FROM forumThreads WHERE threadID = $threadID";
// Execute the query
$result = @($query);
$forum = mysql_fetch_array($result);
$forumID = $forum['forumID'];
}
//if skin is set, make sure they go to the right place
if(isset($userdetails[3])){
$location = "$installDirectory".$userdetails[3]."/";
}else{
$location = "$installDirectory"."default/";
}
?>
<script language="JavaScript">
function submitForm()
{
document.form1.submit();
}
</script>
</head>
<body onLoad="submitForm();">
<form name="form1" method="POST" action="<? echo $location; ?>">
<input type="hidden" name="f" value="<? echo $forumID; ?>">
<input type="hidden" name="t" value="<? echo $threadID; ?>">
</form>
</body>
</html>

Please help me!

If your url looks something like this: "yamoto-studios.com/forum&threadID=234"
then I'd guess that the script was written with the assumption that the php ini value for "register_globals" would always be "on". The assumption should be that it will always be "off", as having it on is deprecated and has been for a long time. In your script, change (after back-up) all occurances of "$threadID" to "$_GET['threadID']".

if that doesn't help then my guess is wrong.
