nome no PHP

Olá,

Eu estou literalmente apanhando com um código PHP aqui para obter o nome do usuário logado.

O problema é que quando eu faço o login vai para o index.php, e nesse index.php tem o header.php incluido que o nome do usuario fique no header.php.

Eu utilizo MySQL como banco de dados, sendo

id - int(10) - Auto_Increment

nome - varchar(100)

usuario - varchar(50)

senha - varchar(50)

rank - int(11)

OBS: Usuário é utilizado para o login

Nome é o que preciso

Segue abaixo os codigos que utilizei

login_valida.php

<?php include('config/db_conecta.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;
}
}

mysql_select_db($database_config, $config);
