I'm quite sure how I should be thinking about this. I have a page creates a report based on parameters that are in the URL. This is important because the user must be able to bookmark the location with the parameters included. For the sake of this example let's say the url looks like this- http://www.myserver.com/news/index_html?UID=11234;skin=modern On that page 'UID' and 'skin' are available to dtml-var. I have a form on that page that take 2 additional input fields from the user(using formulator if that matters). I need to then pass all four values into a dtml method for validation, then into a zsql method. Unfortunately 'UID' and 'skin' are only in the namespace of the initial page, thus this doesn't work. I think the solution would be to make some hidden fields in the form and set their values according to the values on 'UID' and 'skin'. Then once the form results are passed through the validator all 4 values will be available to the zsql method. Is this the most direct way to accomplish this goal?
