This is legacy from the early days when the WMS connection type was
fairly dumb and you needed to provide all the parameters in the
CONNECTION string yourself. The new method is slightly smarter and
allows you to set all the connection parameters (layer name, styles,
etc.) via wms_* metadata entries and in this context this error messages
doesn't make sense.
I had a quick look at the code and unfortunately the fix is not as
simple as removing the error message. I'd suggest you file a bug about
this and we should try to address it before 5.0. In the meantime you'll
have to include QUERY_LAYERS in your URL.

Hi all,
I have defined a WMS based layer in the map file:
CONNECTIONTYPE WMS
CONNECTION "http://myserver/cgi-bin/mapserv?map=owstest.map&";
When trying to use the PHP MapScript (MapServer 4.10) function
'getWMSFeatureInfoURL()' for querying this layer, I get the error
msBuildWMSLayerURL(): WMS Connection String must contain the
QUERY_LAYERS parameter to support GetFeatureInfo requests (with name in
uppercase).
The function is only working correctly if I already put the
"QUERY_LAYERS=layer1,layer2" to the CONNECTION string of the WMS layer
definition in the map file. This is possible but looks a bit strange to
me. Is that an intended behaviour or a bug?
Best regards
Armin
