[mapserver-users] FILTER and FILTERITEM parameters in Map file

Wed Oct 9 17:32:07 EDT 2002

Hi, 

Thanks to many folks for trying to help me out with my FILTER and FILTERITEM
params in my mapfile with 3.6.  So I tried to trouble-shoot with the
suggestions folks provided.  I am in a windows environment and I'm wondering
if my params with the 3.5 test suite are not working because of that or
because I have errored on syntax, not sure.  My map file, html query and
html template files are below if anyone wants to take one more look or test
in their windows environment.  

My error message:  msQueryByAttributes(): Search returned no results. No
matching record(s) found. 

My URL string for 3.3 cgi exe is the following and works just fine (but this
uses the QUERY param in the map file, no FILTERITEM or FILTER params): 

http://gisshare/cgi-bin/mapserv33.exe?map=D%3A%5CInetpub%5Cwwwroot%5Cgis 
share_web%5Cmapserver_demo36%5Citasca%5Ccase1.map&mode=itemquery&item=cty_na
me&value=Anoka 

My URL string for 3.6 cgi exe is the following (same but with qlayer in the
cgi and FILTERITEM and FILTER in map file) but does not work: 

http://gisshare/cgi-bin/mapserv.exe?map=D%3A%5CInetpub%5Cwwwroot%5Cgissh 
are_web%5Cmapserver_demo36%5Citasca%5Ccase1.map&mode=itemquery&qlayer=county
&item=cty_name&value=Anoka
