Get client name from outside of WHMCS

[criat]

I know there are some questions about this already, but I did my homework and still couldn't make it work

 

I'm building a HTML version of my site, after being warned that WHMCS was bad for SEO.

 

Now I have to convert chunks of code like this to HTML:

 

{if $loggedin}
    Hello {$clientsdetails.firstname}
{else}
    Login Form
{/if}

 

I know it should be something like:

 

mysite.com = WHMCS Installation

mysite.com/br = My html website

require("../dbconnect.php");
require("../includes/functions.php");
require("../includes/clientareafunctions.php");

$firstname = $GLOBALS['clientsdetails']['firstname'];  

if ($_SESSION['uid']) {
 echo "Hello $firstname";
} else {
   echo "Login Form";
}

 

But I can't make it work... What can I do?

Update: By using $_SESSION ['ui'] I can tell if the user is logged in or not into WHMCS.

 

Now I just need to echo the variables

I also checked the same and it is working fine in a normal php page. However if trying to call that page in joomla it gives error.

I am also stuck on this. I used the WHMCS integration code to put a login button on the nav bar outside of WHMCS, but would like to change that to a logout button if the client is logged in.

What code can be added to tell if a client is logged in?
