SOLVED! - starting help, using php <-> templates <-> db

[Vaupell]

Got the easy part down, find it easy to work in the control panel enviroment,
but displaying, modifying and editing content back and forth from db.

But now i want to work with user end app's.
I sorta got it narrowed down how to move around inside a php
file using do, get and request. almost like cp area.

and i got vb styled pages working, using header,footer etc.

Let me put up an exsample.

i have some content in the db, i want to show a user.

the user clicks some botton etc and gets to the point where the
content should be shown in the php file,,

So my question is how do i get the php file and templates to work together ?
i can get content from the db using the php file correct ?
and i style the user view with the template correct ?

so the datamovement would go like this db-> php file -> template -> user view
or am i way off.

any articles on this, or suggestions where i can get more info on this
specifik topic. ?
