$result = mysqli_query($qry,$con);
$rows = mysqli_num_rows($qry);
$page_rows = 3;
$last = ceil($rows/$page_rows);
if ($pagenum < 1)
{
$pagenum = 1;

echo " --Page $pagenum of $last--
<p>";
// First we check if we are on page one. If we are then we don't need a
//link to the previous page or the first page so we do nothing. If we aren't

echo $_SESSION['username'];
Would do the trick if you are saving the $_POST username within the session upon successful login. We ideally really need to see the php code you are working with but this is a basic idea of how to accomplish what you're after
