Add field to an AdminCP template?

[Thr33]

I want to add another field in one of the adminCP templates.

To be more specific i want to add another option in the 'paid subscriptions' template. Members can purchase reputation credits which can be used in areas of the site to unlock threads. Currently i must add the rep credits myself when im notified via email. If i was able to add a field in the adminCP for reputation then i could hopefully make it automated.

Im hoping something like this code will work:
$userid = $vbulletin->userinfo['userid'];
$newrep = $vbulletin->userinfo['reputation']+['x'];
$vbulletin->db->query_write("UPDATE user SET reputation=".$newrep." WHERE userid=".$vbulletin->userinfo['userid']);

Any help would be great, thank you.

The adminCP generally doesn't use templates, the pages are printed out by the php code using a set of functions that each print a form element. The best thing to do is probably to look at the php file you're insterested in (under adminCP) and see how it works to produce the page you want to change.

Would anyone know which PHP file and how to edit it correctely? I dont think vBulletin.com forum supports this.
