How to insert a defined php user_id variable within a Dreamweaver login insert

How to insert a defined php user_id variable within a Dreamweaver login
insert

pSo, I built a chat box in php, and now I am trying to build a login form
for that chat application. Right now, in the index page of the chat, I
have a session set up that changes the username, based on their user_id
(it's not secure for right now - i'm just learning). However, for the life
of me, I cannot define that $user_id variable in the Dreamweaver
template./p precodelt;?php require_once('godaddysql.php'); ?gt; lt;?php if
(!function_exists(GetSQLValueString)) { function
GetSQLValueString($theValue, $theType, $theDefinedValue = ,
$theNotDefinedValue = ) { if (PHP_VERSION lt; 6) { $theValue =
get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; } $theValue
= function_exists(mysql_real_escape_string) ?
mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) { case text: $theValue = ($theValue != ) ? ' . $theValue
. ' : NULL; break; case long: case int: $theValue = ($theValue != ) ?
intval($theValue) : NULL; break; case double: $theValue = ($theValue != )
? doubleval($theValue) : NULL; break; case date: $theValue = ($theValue !=
) ? ' . $theValue . ' : NULL; break; case defined: $theValue = ($theValue
!= ) ? $theDefinedValue : $theNotDefinedValue; break; } return $theValue;
} } ?gt; lt;?php // *** Validate request to login to this site. if
