Hi, It's an issue with MapServer. If the returned html shows only "[NAME]" as in the template, then it means, that MapServer couldn't resolve the tag. Perhaps you have no column NAME in your data or it's an issue with upper and lowercase.
Try 'wms_feature_info_mime_type' 'text/plain' 'wms_include_items' 'all' To get the result with all attributes, that are availible.

Mai 2010 10:14 An: [email protected] Betreff: [OpenLayers-Users] GetFeatureInfo returns attribute nameonly(Mapserver & Openlayers) I have been trying for a long time(since february 2010) to use GetFeatureInfo to display the attributes of a clicked polygon feature . The map is displayed in OpenLayers 2.8 which uses a mapserver 5.6.1 for the mapfile whose data source is a shapefile. When i click on a polygon feature, i only get the attribute name "[NAME]" (as it appears on the html body template file) AND not the atrribute values. Please help.Here is the openlayers file contents; <html> <head><title>OpenLayers project</title> <style type="text/css"> #map { width: 800px; height: 600px; border: 1px solid black; } </style> <script src="http://openlayers.org/api/OpenLayers.js";></script> <script type="text/javascript"> function init() { var map = new OpenLayers.Map('map'); var dcs = new OpenLayers.Layer.WMS( 'Admin Districts', 'http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/cgi-bin/Districts2. map&', {layers: 'Botswana_Admin_Districts'} ); map.addLayer(dcs); map.setCenter(new OpenLayers.LonLat(25,-24),6); // Tie click event to WMS GetFeatureInfo call map.events.register('click', map, function (e) { var url = "http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/cgi-bin/Districts2. map&" + "?REQUEST=GetFeatureInfo" + "&EXCEPTIONS=application/vnd.ogc.se_xml" + "&BBOX=" + map.getExtent().toBBOX() + "&X=" + e.xy.x + "&Y=" + e.xy.y + "&INFO_FORMAT=text/html" + "&QUERY_LAYERS=Botswana_Admin_Districts" + "&LAYERS=Botswana_Admin_Districts" + "&FEATURE_COUNT=5" + "&SRS=EPSG:4326" + "&STYLES=" + "&WIDTH=" + map.size.w + "&HEIGHT=" + map.size.h; window.open(url, "GetFeatureInfo", "location=0,status=0,scrollbars=1,width=600,height=150" ); }); } </script> </head> <body onload="init()"> <h2>OpenLayers Example</h2> <div id='map'></div> </body> </html> and the mapfile; MAP NAME "Districts2" # Map image size SIZE 400 400 UNITS dd EXTENT 15.807570 -27.131403 33.564789 -17.550001 SHAPEPATH 'C:\ms4w\PSI_Shapefiles\' #FONTSET './fonts/fonts.txt' SYMBOLSET 'C:\ms4w\Apache\cgi-bin\Symbols.sym' PROJECTION 'proj=longlat' 'ellps=WGS84' 'datum=WGS84' 'no_defs' END # Background color for the map canvas -- change as desired IMAGECOLOR 255 255 255 IMAGEQUALITY 95 IMAGETYPE agg OUTPUTFORMAT NAME agg DRIVER AGG/PNG IMAGEMODE RGB END # Legend LEGEND IMAGECOLOR 255 255 255 STATUS ON KEYSIZE 18 12 LABEL TYPE BITMAP SIZE MEDIUM COLOR 0 0 89 END END # Web interface definition.
