[mapserver-users] No filter defined on itemquery.

[Ryan, Adam]

I struggled through the same thing.  The solution is to set the layer's
filter and filteritem to your value and item respectively, but I don't
understand why either.  Watch for punctuation.

Subject: [mapserver-users] No filter defined on itemquery.


When I try to itemquery a Postal Code layer, I get:
msQueryByAttributes(): Query error. Requested layer has no filter defined. 
 
My URL looks like this:
http://myserver/cgi-bin/mapserv.exe?map=d%3A%5CMapServer%5CMAPFiles%5CMOMap.
map&program=%2Fcgi-bin%2Fmapserv.exe&map_web_imagepath=d%3A%5Cinetpub%5Cwwwr
oot%5Ctemp%5C&map_web_imageurl=%2Ftemp%2F&mode=itemquery&value=63105&qlayer=
Zip+Codes&item=ZIP&mapext=shapes
 
I've included the layer definition at the bottom of this email.  I don't
understand.  Why do I need a filter?  What filter do I need?  I've read
everything about this I could find before asking you, but the documentation
on FILTER is very brief, and the mail archives didn't provide a solution.  I
should point out that I'm using OGR MapInfo TAB data.
 
Thanks in advance,
Dan Martin
