PHP MapScript getWMSFeatureInfoURL()

[Daniel Morissette]

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.
