I have a catalog aware ZClass publication object that I want to have searchable. There
are 3 criteria I want users to be able to select in addition to a search string
I created field indexes for the criteria in the zCatalog, and made a form where users
can select the indexes with checkboxes to limit their search. The selected items are
then passed to my search method - which in turn executes a <dtml-in> to produce the
The whole thing works great, until I decided to try to add column sorting
functionality (Like the zope downloads page). Here is the problem, I run the query
and the page comes up correctly on the first iteration, but when I try to sort the
column (with a ?sort_on=index "get" request), the selected criteria are forgotten and
the entire result set is returned sorted.
for example, one of my search criteria is "theme" - there are four possible (Air,
Land, Water, and Waste).
the request would look like:
I can't figure out how to pass a list in the get request. How do I pass more than one
theme to the method as a list? I have discovered through trial and error that I can
pass it the values if I repeat theme for each list item. However, I also have a
criteria - "category" with over 32 items, and a criteria - "division" with 14 items.
This becomes extremely clumsy with
"category=reports&category=guidebooks&division=lwm&division=aqd" etc. repeated 32
times. Not to mention that there is a limit of how much info I can pass in the get
Is there a better way to pass the lists to my method?
Thanks in advance!
