Add the php code for the hook (see my prev post) at the top of the custom code section of your custom php file.
To disallow usergroups from this custom php page add this to the plugin:

PHP Code:

if (is_member_of($vbulletin->userinfo, 1,2,3))
{
        print_no_permission(); 
        exit(); 
} 


This will prevent all members from the usergroups 1,2,3 to see the page. To turn it around use

PHP Code:

if (!is_member_of($vbulletin->userinfo, 1,2,3)) 


Note the ! in front of is_member_of. This will prevent all users except usergroups 1,2,3 from accessing the page, so only members of usergroups 1,2,3 will be able to see it.

No, this will add no option to your admincp. This adds a normal hook, and you would need to edit the plugin in the plugin sectin of AdminCP. If this is for your own use only, this is the way I'd do it. An AdminCP option just adds unnecessary overhead. Honestly, I wouldn't even add that hook. Just edit your custom php file directly - thats the most performant and simple way, really.

And once again: This code does not block access to templates. It blocks access to the whole php file, so to say.
