if loggedin for external use

[clever-host]

Hello

 I want to integrate whmcs login form into a html or php page, but i need a function like this:

{if $loggedin}
Client Area Button
{else}
Login Button
{/if}

This function can be used into whmcs template.

You have any idea if there exist any function like this for external use? 

 

Thank you.

Can you define external? Will it be on the same server?

Hello

Yes, on the same website/server. 

I want to use this function on html template.
