Fw: [Mapserver-users] set filter with cgi

[Steve Lime]

Between 3.6.x and 3.7 (now 4.0 given all the changes) there was a major
change in how attribute queries are done. It should be more straight
forward. I will try to fix the test suite to run against 4.0 and will
post a note to the list yet this week about its availability.

Note that attribute queries were the only ones to under go outward
change between releases.

Hi Babak,
in MS 3.6 I only set FILTERITEM without FILTER for a give layer.
In the cgi querystring, then, i use this:

http://laplace/mapserver/mapserv.exe
?map=calabria/calabria.map
&imgsize=863+384
&qlayer=myLayer
&mode=itemquerymap
&map_myLayer_filter=COSENZA

and everything's right.
Unfortunately i tried to use the same syntax with 3.7 version and obtain
an
error:

msQueryByAttributes(): Query error. No query expression defined.

i don't know why.... if someone does I'll appreciate any hint and/or
clarification...
