[OpenLayers-Users] getFeatureInfo and variable substitution
Hi,
I got an error when querying a wms layer (mapserver) with a
OpenLayers.Control.WMSGetFeatureInfo request when there is a variables
substitution.
I have a WMS layer define like this:
createWmsLayer('ecoles', '.../cgi-bin/mapserv.exe?map=MYMAP',{layers:
'ecoles', transparent: "true", format:"image/gif", SEMCDC:thisCDC, RSS:
thisRSS, ORDRE: thisOrdre},{isBaseLayer: false, visibility:
false,singleTile:true,transitionEffect: 'resize'});
I have 3 variables: SEMCDC, RSS, ORDRE
In the mapfile I use this statement
FILTER "semcdc in (%SEMCDC%) and rss in (%RSS%) and ordre in (%ORDRE%)"
The getMap request is succesfull.
Here is the request
/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 "

5807991.15001926)'::BOX3D,900913) )
</ServiceException>
</ServiceExceptionReport>
How should I query the layer?
Thanks
