Print custom templates.

[Sama34]

Yes, the structure of my page is like this:
htdocs
-/forums/
-/index.php

index.php use the login form for the forum, later I found it very convenient, as I can style inserting the forum header and alike.

But now I want to make it so that I can insert not just mybb default/valid variables, now I want to be able to insert a custom template directly into my index.php file and modify the template from the Mybb ACP.

I don't know that much about php, I will check the eval() funtion.
