[mapserver-users] Filter on attribute - how?

[Steve White]

I want to pass in a string of values in one variable and filter on them as
if they are in an OR clause.

 

I've tried the following which works fine:

 

FILTER "Castles"

FILTERITEM "CategoryNa"

 

Now I want to filter on 2 sets like this:

 

FILTER "Castles OR Battlefields"

FILTERITEM "CategoryNa"

 

I'm hardcoding them in the mapfile initially so I know they work, but
eventually I want to use a variable:

 

FILTER "%filtervar%"

FILTERITEM "CategoryNa"

 

The variable substitution works for just one type, but how do I use multiple
types?

 

Cheers,

 

Steve
