functions not working

[msi3753]

i tried to modify some code to use an existing database for logins, but another database for storing information. i am having problems login in with the edited code, any help would be great.

original code

function loginaction($username, $password) {
  global $uid;
  dbconnect();
  $query = "SELECT * FROM IPM_users WHERE username='$username'";
  if (!($result = mysql_query($query))) {
  	die("Couldn't retrieve authorization data, please try again later");
  }
  if (mysql_num_rows($result) > 0) {
  	if ($user=mysql_fetch_array($result)) {
  	  if (md5($password) == $user[password]) {
        ($SECURE_COOKIES == "true")? $SSL=1: $SSL=0;
        setcookie("uid", $user[id], "0", "", "", $SSL);
        $uid = $user[id];
        mytasks();
      } else {
        login();
      }
    }
  } else {
    login();
  }
}

modified code

function loginaction($username, $password) {
        global $uid;
        dbconnect2();
        function authMysql ($username, $password, $db_username2, $db_password2, $db_servername2, $db_dbname2, $db_table2) {
        $connection = mysql_connect($db_servername2, $db_username2, $db_password2) or die("Invalid server or user or something");
        mysql_select_db($db_dbname2);
        $query = "select username, password, password('$password') from $table where username = '$username'";
        $result = mysql_db_query($db_dbname2, $query, $connection) or die ("error in query: $query");
        $dbrow = mysql_fetch_array($result, MYSQL_NUM);
        $pass = $dbrow[1];
        $pass2 = $dbrow[2];

    if ($pass == $pass2) {

        dbconnect();
        $query="SELECT id FROM IPM_users WHERE username='$username'";
        $result=mysql_query($query);

        if (mysql_num_rows($result) > 0) {
            if ($user=mysql_fetch_array($result)) {
                if (md5($password) == $user[password]) {
                    ($SECURE_COOKIES == "true")? $SSL=1: $SSL=0;
                    setcookie("uid", $user[id], "0", "", "", $SSL);
                    $uid = $user[id];
                    mytasks();

                } elseif (mysql_num_rows($result) < 0) {
                    $query="INSERT INTO IPM_users VALUES  (NULL,'$username','NULL','$username','defaultgroup','$[e-mail]','1')";
                    mysql_query($query);

                    if (md5($password) == $user[password]) {
                        ($SECURE_COOKIES == "true")? $SSL=1: $SSL=0;
                        setcookie("uid", $user[id], "0", "", "", $SSL);
                        $uid = $user[id];
                        mytask();

                    } else {
                      login();
                    }
                }
            }
        }
    }
}
}

I hope someone is able to donate a small amount of their time to help me with this. Thank you very much. - TonyR
