สอบถามเรื่อง Link หน่อยครับ

พอดีติดปัญหาต้องแก้ code ของคนเก่า

index.php

<?php
error_reporting(E_ALL & ~E_NOTICE);
require_once('header.php');
require_once(basename(($_GET['page']!='' ? $_GET['page'] : 'home') . '.php'));
require_once('footer.php');
?>

ตัวนี้คือตัว Link

<a href="?page=myprofile?uid=<?=$_SESSION['member_id'];?>" style="color: #ABABAB">ข้อมูลส่วนตัว</a>

myprofile.php

<?php 
include("administrator/connectdb.php");
include ("administrator/function.php");

if(isset($_GET['uid']) && (!isset($_POST['username']))){
	    $id = $_GET['uid'];
        $SQL = "select * from member where id = '$id'     ";
	    $RS = mysql_query($SQL);
	    $arr = mysql_fetch_array($RS);
	    $username = $arr['username'];  
	    $password = $arr['password'];  
	    $firstname = $arr['firstname'];

	    $fax = $arr['fax'];  
	    $img = $arr['img'];  
	    $btn ="Update";
