[Schmidt, Allen J]

I have a page that uses a dtml-in to process the results from a ZSQL method. The page lists out 30 items and the price of each item is a link to a detail page. What I would like to do is while inside the loop, create then append to a list that stores each of the record IDs for each item. Then when someone clicks the link to go to the detail page it 'takes' the list along. On the detail page would be info about the product and also include forward and back buttons to the next item in the list just created.

I guess the question is can I create a list that I can pass to the next page to use to access subsequent records.

First you need a candidate HTML plan, then you can figure out how to build it with Zope. The most HTML-ish way is to use hidden fields in an HTML form. All the hidden fields can have the same name, then their values will be stored in the REQUEST for the page as a list that you can iterate over or whatever. If your loop through the ZSQL results already occurs in a form, you can just add the hidden field at each iteration. Otherwise, you probably will have to use a second pass through the results to build the form with the hidden fields. If you have to create a separate form for the hidden list, you will have to use javascript to submit the form when the user clicks the detail link. You can get that to happen inside an html href link like this: <a href='javascript:dispatch(id)'>Click here for details page</a> Here, "dispatch()" is a function you write, and "id" is a value (written by Zope) that tells dispatch() which item to dispatch, or perhaps where to link to (probably it will be a url).
