You're probably better off with LOAD, but if you don't want to use Ajax,
maybe exec_environment would work:

Does options() have to be a controller action (i.e., does it ever need to be
called via a URL)? If not, you could also simply put it in a module and
import it wherever you need it. In that case, I suppose you'd have to
explicitly pass db to it as an argument.
