using a form to define a variable? (not so simple?)

[A2xA]

Let's see if I can explain this.  The chat I have writes to a txt file.  So, I gave the users the option to make their own "hub"  Which makes their own text file.  I need to make it where they type in their text file's name/or number and it takes them to "their hub".  The only problem is the php file where I'm trying to define it are the settings for a swf file, which is the actual file I'm running..

 

 

the php settings file for the chat:

 

<?php
extract($HTTP_GET_VARS);
extract($HTTP_POST_VARS);
header("Expires: ".gmdate("D, d M Y H:i:s")."GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
?>
<?php
$nickname = str_replace ("\n"," ", $nickname);
$nickname = str_replace ("<", " ", $nickname);
$nickname = str_replace (">", " ", $nickname);
$nickname = str_replace ("fuck", "-", $nickname);
$nickname = str_replace ("suck", "-", $nickname);
$nickname = str_replace ("ass", "-", $nickname);
$nickname = str_replace ("&", "and", $nickname);
$nickname = stripslashes ($nickname);
$message = str_replace ("\n"," ", $message);
$message = str_replace ("<", " ", $message);
$message = str_replace ("&","and", $message);
$message = str_replace ("fuck", "-", $message);
$message = str_replace ("suck", "-", $message);
$message = str_replace ("ass", "-", $message);
$message = stripslashes ($message);
$p=gmdate("d M H:i");
?>
&output=
<?php
$chat_file = "shout.txt <-- What I'm trying to define as a variable";
$chat_lenght = 40;
$max_single_msg_lenght = 100000;
$max_file_size = $chat_lenght * $max_single_msg_lenght;
$file_size= filesize($chat_file);
if ($file_size > $max_file_size) {
$lines = file($chat_file);
$a = count($lines);
$u = $a - $chat_lenght;
for($i = $a; $i >= $u ;$i--){
$msg_old =  $lines[$i] . $msg_old;
}
$deleted = unlink($chat_file);
$fp = fopen($chat_file, "a+");
$fw = fwrite($fp, $msg_old);
fclose($fp);
}
$msg = str_replace ("\n"," ", $message);
$msg = stripslashes ($msg);
if ($msg != ""){
$fp = fopen($chat_file, "a+");
$fw = fwrite($fp, "<font color=\"blue\"><b>$nickname:($p)<br></b></font> $msg\n");
fclose($fp);}
$lines = file($chat_file);
$a = count($lines);
$u = $a - $chat_lenght;
for($i = $a; $i >= $u ;$i--){
echo $lines[$i];
}

?>

 

^ignore the cuss words they are filters  ^

 

on the 28th line there is $chat_file = "shout.txt";  Instead of shout.txt I want it to be the users custom indentifier ie: hub232.txt

 

Then, somehow re-direct to the flash file?

 

 

I know this is very...very confusing.  If anyone it getting what I'm saying and can help I'd appreciate it.  I sure can't wrap my mind around it  :-X
