How to run a WHMCS hook for any one template

I want to run a hook only one template? I mean the primary navigation bar hook should be run if anyone access the WHMCS by using `index.php?systpl=six` Not on any other template.

Thanks.

Currently, WHMCS developer documentation doesn't provide a way to get the current template for menus hooks.

But I noticed that there is a global variable that have the active template, you need to test through all pages to make sure code is working, I tested on Client Services page:

function my_custom_navs_func() {

global $inputParams;

$activeTemplate = $inputParams['clientareatemplate'];

if ($activeTemplate == 'six') {

//Do something here!
}
}
add_hook('ClientAreaNavbars', 1, 'my_custom_navs_func');
