[OpenLayers-Users] WFS GetFeature with Mapserver

[Attila Berényi]

Dear All,

Finally I've succeed applying WFS GetFeature (based on the GeoServer  
example here: http://openlayers.org/dev/examples/getfeature-wfs.html)  
with MapServer, and hereby I will share my experiences to give some  
help for the users with the same problem.

So, using WFS GetFeature function needs a few things to be done to  
work correctly:
1. Take care if you use the sample wrapper CGI from here  
http://mapserver.org/cgi/wrapper.html, it accepts only GET requests,  
and you need POST. Pick one from these  
http://mapserver.org/ogc/wms_server.html#more-about-the-online-resource-url  
instead.
2. The lastest MapServer (as of now 5.6.3) needs to be patched in  
order to return geometry on WFS requests (needed for e.g. highlight  
functions), see: http://trac.osgeo.org/mapserver/ticket/3235
3. You need to set a few extra arguments to  
OpenLayers.Protocol.WFS.fromWMSLayer, such as featurePrefix,  
geometryName and featureType.

Thanks to all who helped me, and I hope this would be useful, you can  
see a working example (with hover and selection functionality) here:  
http://webgis.fmt.bme.hu/gfi/t4.html. I'm sorry, this is an old  
server, it might be slow.

Now I try to apply this function for multiple typenames (layers), but  
that worth a different thread  :)

BR,

Attila
