Hi, I already posted this problem on openlayers list, but it might be a mapserver issue.
OpenLayers.Control.WMSGetFeatureInfo doesn't use the FILTER key in my mapfile. This filter is define with variables like this: FILTER "semcdc in (%SEMCDC%) and rss in (%RSS%) and ordre in (%ORDRE%)" . The getMap request is succesfull but not the GetFeatureInfo request Here is the request GetFeatureInfo /cgi-bin/mapserv.exe?map=MYMAP service=WMS&version=1.1.0&request=GetFeatureInfo&layers=ecoles&query_layers=ecoles&styles=&bbox=-8820221.560815%2C5721770.182129%2C-7587445.168853%2C6361395.234705&srs=EPSG%3A900913&feature_count=3000&x=272&y=457&height=523&width=1008&info_format=text%2Fhtml Here is the response <?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?> <!DOCTYPE ServiceExceptionReport SYSTEM " http://schemas.opengis.net/wms/1.1.0/exception_1_1_0.dtd";> <ServiceExceptionReport version="1.1.0"> <ServiceException> prepare_database(): Query error.
