> A slightly more flexible way to setup Smarty is to extend the class and
initialize your Smarty environment. So instead of repeatedly setting
directory paths, assigning the same vars, etc., we can do that in one place.
Lets create a new directory <TT
CLASS="filename"
>/php/includes/guestbook/</TT
>
and make a new file called <TT
CLASS="filename"
>setup.php</TT
>. In our example
environment, <TT
CLASS="filename"
>/php/includes</TT
> is in our include_path.
Be sure you set this up too, or use absolute file paths.
