Hi, I have a question about using the mapfile Filter option with variable substitution. In my user interface (OpenLayers), I have drop down boxes that allow users to filter the data display based on selected year and selected category. Accordingly, I have two filters set up in my mapfile:
FILTER "year = %selected_year%" FILTER "category=%selected_category%" What if the user wants to see data for all years or for all categories? Is there a way that I can submit a wildcard in my mapserv URL instead? Or is there some other way to do this? My data source is a PostGIS.
