Hi Jake,
I originally had trouble coming to grips with the concept of variables and
forms and passing them from one object to the next. After much testing,
trial and error (and guidance from this list), I came up with these
conclusions (which I'm sure someone will shoot down if I am wrong):
1) The request object you are setting with your REQUEST.set command is like
a big bucket that gets passed between one web page and the next when you
call it in your DTML. The best thing someone ever showed me was how to view
in the called document ie.
insert the line:
<dtml-var REQUEST>
into the dtml/method you are trying to call.
If you do that you can see all of the variables that get passed normally as
part of your REQUEST variable, as well as any that get added to it by your
form in the act of your POST command in the form. Be prepared - it is a
long list! You should be able to see all your form variables in there. If
you don't then you haven't been doing your form correctly (been there done
that too!).
The only real 'nasty' I have come across so far id the checkbox - if it is
unchecked it doesn't post anything to the REQUEST object, and then you need
to check for it and set it, if you are using it to update an SQL database
(this is the only time I use the <dtml-call
"REQUEST.set['argument','value']">command. This is normal behaviour with
forms and is not the fault of Zope.
Hope this helps...
