Is it still possible to use a variable for the value of CLASSITEM? We're
passing the field name to be used in the CLASSes in the URL as a variable
(%dmmethod%):
CLASSITEM '%dmmethod%'
FILTER ('[type]'='County')
STATUS on
CLASS
NAME 'No Drought'
EXPRESSION ('[%dmmethod%]'='-1')
STYLE
COLOR 255 255 255
OUTLINECOLOR 20 20 20
END
END
This used to work in previous versions. There are 6 different fields that
could be searched, for 6 possible values. I'd really like to avoid creating 36
classes for each layer that uses this attribute table. I am including dmmethod
in a validation block in each layer trying to use this variable. Mapserver
version is 6.0.3
Any suggestions would be greatly appreciated.
Thank you.
