I am using mapserver CGI with shapefiles, and have a web
interface that includes a rubberband – type of area selection
tool. I use itemnquerymap mode to highlight certain polygons, which
works fine. However, if the user selects an area with the rubberband tool
that does not include one of the queried polygons, mapserver generates an
error: msQueryByAttributes(): Search returned no results. No matching
record(s) found and a red X is displayed in the web page. Is there a trick I could
do that would cause the map to be generated, even if no matches were found in
the query? David S. Hunter |
