Variable Substitution in Filter expression

Wed Apr 26 03:26:29 EDT 2006

Hi All,

I'm running mapserver 4.4.1.

I've been trying to use a %variable% substitution to dynamically filter
a shapefile. I have tried several combinations however none seem to
work. The following filter works...

FILTER ("[ROAD_NAME]" == "SMITH ST")

However, attempting to use...

FILTER ("[ROAD_NAME]" == "%street%")

with the URL...

mapserv.exe?map=variable.map&request=getmap&version=1.1.1&service=wms&la
yers=roads,copyright,lga,cadastre&BBOX=115.96538,-31.90127,115.96738,-31
.89927&street="SMITH%20ST"

does not.

I've had no joy with any of the following either...

         FILTER "ROAD_NAME = '%street%'"
or
     FILTERITEM 'ROAD_NAME'
     FILTER '%street%'

Any suggestions appreciated.

Cheers

Ben
