Supply a valid <A

>template resource</A

type and path. As an optional second parameter, you can pass a
<TT
CLASS="parameter"
><I
>$cache id</I
></TT
>, see the
<A
HREF="caching.html"
>caching section</A
> for more information.
</P

> As an optional third parameter, you can pass a
<TT
CLASS="parameter"
><I
>$compile_id</I
></TT
>.
This is in the event that you want to compile different versions of
the same template, such as having separate templates compiled
for different languages. Another use for
<TT
CLASS="parameter"
><I
>$compile_id</I
></TT
> is when you use more than one
<A
HREF="api.variables.html#variable.template.dir"
><TT
CLASS="parameter"
><I
>$template_dir</I
></TT
></A
>
but only one
<A
HREF="variable.compile.dir.html"
><TT
CLASS="parameter"
><I
>$compile_dir</I
></TT
></A
>.
Set a separate <TT
CLASS="parameter"
><I
>$compile_id</I
></TT
> for each
<A
HREF="api.variables.html#variable.template.dir"
><TT
CLASS="parameter"
><I
>$template_dir</I
></TT
></A
>,
otherwise templates of the same name will overwrite each other. You can
also set the <A
HREF="variable.compile.id.html"
> <TT
CLASS="parameter"
><I
>$compile_id</I
></TT
></A
> variable once instead of passing
this to each call to this function.
