I'm working offline, so can't see what you're refering to.
The solution that I have come to is to simply set a cookie and serve up
the correct fields based on the cookie:
dtml-if 17 in list_map_dir_id and 21 not in list_map_dir_id
dtml-call RESPONSE.setCookie(list_type,'lodge')
dtml-elif 21 in list_map_dir_id and 17 not in list_map_dir_id
dtml-call RESPONSE.setCookie(list_type,'resto')
dtml-elif 21 in list_map_dir_id and 17 in list_map_dir_id
dtml-call RESPONSE.setCookie(list_type,'restolodge')
dtml-else
dtml-call RESPONSE.setCookie(list_type,'other')
/dtml-if
dtml-in insert_listing1_sql
id: dtml-var newid
dtml-call REQUEST.set('list_map_list_id', newid)
/dtml-in
dtml-call insert_listing_map_sql
dtml-call
RESPONSE.redirect('add_listing2?list_id=%s'%(REQUEST['list_map_list_id']))
Oh my god! What the hell are you doing? Want some plyers to pull your
fingernails out while you're at it?!
I am sure there are more elegant ways to do this - the client wanted
the data in a RDBMS for portabilityyah yah yah
...and it looks like you don't have a clue about relational databases.
Sounds like you want to have an establishments table, a features
table, and then learn to do a join on both to get the features for a
given establishment.
sheesh, I'm on the verge of tears having read the above...
cheers,
Chris

Re: [Zope] checking for elements in a list
Thanks Peter,
The conditional within the dtml did the trick.
This is a continuation of this issue (a bit cumbersome):

add_listing2 is the form that displays restaurant specific fields

both...those tricky motel/restaurants in rural NM...
It seems that if I try this after the list is inserted, it comes out of
MySQL as a string, not integer and therefore I could not iterate to
check membership in the list.

Re: [Zope] checking for elements in a list
I suggest you try a little scripting language called Python.
You can use in inside Zope by creating Python Scripts (formal name:
Script (Python))
Try to stay away from DTML as much as possible. It's only about as
good as PHP alone.

Re: [Zope] checking for elements in a list
You should definitely move such *complex* logic into a PythonScript. DTML is made for generating content but not to implement such complex logic...and of course the elif part won't work because that's the semantic of if-elif. -aj --On 2.
