how to add a new tab to tickets?

[ramf]

Hi,
I want to add a new tab to the tickets in WHMCS - this new tab should be a form that I can select some information in and send it via webhook and to add this information as a ticket note.

 

So the first step is to add a new tab to the ticket - right?
So I tried doing it the same way that @busyrack are doing it with the excellent ticket timer module. 

I found this documentation by jas8522:
https://github.com/websavers/WHMCS-admin-tab-creator-library/tree/master

And I tried to create a new module with 3 fiels:

new_tab.php - This file contains the module name, version number, author, description, and any custom configuration fields.
hooks.php - This file defines the hooks that the module should define within WHMCS. In our case, it is the AdminAreaFooterOutput hook exactly as mentioned in the git above
busyrack_admin_tabs.js - This file adds the tab to the supporttickets page and shows the tab content - the same one from the git abov.

 

But it's not working for me - no tab is added to the ticket.

Can some one please help?

Regards,

Ram
