Queries

[Pericles S. Nacionales]

Peter,

Check http://terrasip.gis.umn.edu/projects/tutorial/section3.html and 
look at the map and template files for each example.  I'm currently in 
the process of updating the tutorial and it will make more sense when 
I'm done...  perhaps in the next two weeks.

Anyway, to setup a non-spatial query in MapServer (generating maps is a 
form of query too!) you need to define a query template in each layer to 
be queried.  In addition, you might also want to define a header and 
footer for each of the layer.  Attached you will find the relevant 
template files and a mapfile.  Open the mapfile and have a look at the 
layer named cities_poly and also the web object--that's where all the 
query-related parameters are defined.

As for the interface, I don't know about Chameleon but in the MapServer 
CGI world you invoke queries by changing the mode to query or nquery.  I 
suspect it would be the same thing with PHP/MapScript.

Good luck!
-Perry
