I was able to extract the ids from the product and services home panel, then i would loop those ids and get the product details. My first try was to insert the tpl file with the same parameters like the nav bar. However it seems like it doesn't work and seems like the wrong approach as you mentioned.
How would i query the database and show said data? I am also new to hooks and WHMCS, and i couldn't figure out how i get the client id to start a query or hook or if i need a hook or even how to read the hook. Thanks in advance!
