<?php 
$fetch_users_data = mysql_fetch_object(mysql_query("SELECT * FROM `members` WHERE username='".$_SESSION['username']."'"));

$ref_id=$fetch_users_data->id;
if(isset($_GET['join'])){
$referral_ID = $_GET['join'];
$referral_string= "?join=".$referral_ID;
}
$membername= $fetch_users_data->username; //don't change

?>

 

and I want to add

a $subid

 

whitch code is correct:

 

$subid = $_SESSION['username'];

 

or

 

$subid = $membername;

 

please someone who knows php and not just quesses. thanks guys.
