[Custom Page] User Authentication Integration

[Northern Host]

I have my website built around WHMCS. The issue I'm running into is that even though the user is logged in, they must visit the client area first upon each new visit to the site in order to show they are authenticated, then everything is fine. Is it possible to change this, because I have it say "Welcome Back, User" at the top of my home page and they can't see it unless they are logged in.

 

This is the code I have at the top of my custom pages.

<?php 
require($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR."clients/init.php");
$whmcs = new WHMCS_ClientArea();

if ($whmcs->isLoggedIn()) {
$whmcs_result = mysql_query("SELECT * FROM tblclients WHERE id=".$whmcs->getUserID());
  	$whmcs_data = mysql_fetch_array($whmcs_result, MYSQL_ASSOC);
}
?>
