It seems like it would be possible to implement more
of this recipe with the httpvariables recipe using
(untested):
(:session currencies[] EUR:)
(:session currencies[] GBP:)
(:session currencies[] USD:)
You may need to use indexes for that to work. This
leads me to the idea of adding a new shorthand to help
set arrays with the httpvariables recipe making it
even easier? Maybe something like:
(:session currencies[] EUR GPB USD :)
Apply that to cookie assignment also. What do you
think?
Now, I think that your recipe could be implemented
with just a bunch of select statements:
(:input default currency {$~currency}:)
(:input select name=currency value={$~currencies[1]}:)
(:input select name=currency value={$~currencies[2]}:)
(:input select name=currency value={$~currencies[3]}:)
Maybe then a new form of select markup that would make
this easier would be something like:
(:input default currency {$~currency}:)
(:input selectlist name=currency
values={$~currencies[1]},{$~currencies[1]},{$~currencies[1]}:)
I could then see expanding the httpvariables recipe
again, this time to perform array expansion with a
separator so that you could now write:
(:input default currency {$~currency}:)
(:input selectlist name=currency
values={$~currencies[(,)]}:)
Not to hard to fathom is it?
