[mapserver-users] itemquery

[Puneet Kishor]

Hi Steve,

Thanks once again for your reply. Here are some specifics...

I am using 3.4, which of course has its own related issues (existing docs
are for 3.3x, so a bunch of keywords are hit-and-miss). Anyway, I am using
3.4, not 3.5.

that is why I am so surprised that it doesn't work.

I am not setting an explicit mapextent... simply using the all inclusive
default map extent. That said, I am not even reaching that far... I would be
happy if msQueryUsingItem() simply found the shape where item=MCD_NAME and
value=MADISON. Once it can query and find correctly, only then will I worry
about mapping that feature.

I think so... it looks like so...

LAYER
  NAME mcds
  TYPE polygon
  STATUS on
  DATA "shapes/boundaries/mcdppoly" 
  CLASSITEM mcd_name
  CLASS 
    NAME "MCDs"
    EXPRESSION /./
    OUTLINECOLOR 128 128 128
    COLOR 245 245 245
  END
  HEADER "mcds_header.html"
  FOOTER "mcds_footer.html"
  QUERY
    TEMPLATE "mcds.html"    
  END
END
