Anyone know how to insert to multiple tables on Dreamweaver?

Question

Hey everyone,
I'm a bit of a newbie at PHP and am trying to create my first "dynamic" site.  I have a registration table with fields idNo (primary key & auto-increment), username, password, email.  I also have another table called profile with fields idNo, location, musicalInfluences, aboutMe etc.  All of these fields except idNo have the default value of "update."  What I want to be able to do is add a second insert statement to the user registration behaviour so that I can have the idNo number added to the profile tables as well as the registration table.  That way the registration and profile are linked by idNo and I can create a record-set do automatically populate the profile table on my profile page when the user logs in.  All of the different profile traits would say "update" and I can then use an update server behaviour for the user to update there profile.
I might be approaching this the wrong way so I'm open to suggestions on how to create a user login and linked profile page.  One thing I could not work out was how, when the user clicks login with the correct credentials,  I was supposed to separate a first time user, directed to the create profile page, from a user who has already created a profile page and just wants to see it.  The only way I could think of was by using the default method explained before and then having an update page.  Sorry if that was a bit of a waffle.  Here is my code.  Any help would be much appreciated!!
This is the script that I have included on my registration page.  I just extracted the php and used an include to keep the html page tidy.
<?php require_once('Connections/soundstorm.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  if (PHP_VERSION < 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;
// *** Redirect if username exists
$MM_flag="MM_insert";
if (isset($_POST[$MM_flag])) {
  $MM_dupKeyRedirect="usernameExists.php";
  $loginUsername = $_POST['username'];
  $LoginRS__query = sprintf("SELECT username FROM registration WHERE username=%s", GetSQLValueString($loginUsername, "text"));
  mysql_select_db($database_soundstorm, $soundstorm);
  $LoginRS=mysql_query($LoginRS__query, $soundstorm) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  //if there is a row in the database, the username was found - can not add the requested username
  if($loginFoundUser){
    $MM_qsChar = "?";
    //append the username to the redirect page
    if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
    $MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
    header ("Location: $MM_dupKeyRedirect");
    exit;
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "registerForm")) {
  $insertSQL = sprintf("INSERT INTO registration (username, password, email) VALUES (%s, %s, %s)",
                       GetSQLValueString($_POST['username'], "text"),
                       GetSQLValueString($_POST['password'], "text"),
                       GetSQLValueString($_POST['email'], "text"));
  mysql_select_db($database_soundstorm, $soundstorm);
  $Result1 = mysql_query($insertSQL, $soundstorm) or die(mysql_error());
  $insertGoTo = "registerSuccess.html";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  header(sprintf("Location: %s", $insertGoTo));
?>

you can use a trigger in mysql. this trigger is for new records in your registration table. you can use mysql's last_insert_id() to get the last record inserted. just search for mysql triggers to get more info. note that this is not php code, it is mysql.
