<div class=Section1>
<p class=MsoNormal><span lang=EN-GB>I want to pass in a string of values in one
variable and filter on them as if they are in an OR clause.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>I’ve tried the following which works
fine:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTER "Castles"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTERITEM "CategoryNa"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>Now I want to filter on 2 sets like this:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTER "Castles OR Battlefields"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTERITEM "CategoryNa"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>I’m hardcoding them in the mapfile
initially so I know they work, but eventually I want to use a variable:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTER "%filtervar%"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>FILTERITEM "CategoryNa"<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>The variable substitution works for just
one type, but how do I use multiple types?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>Cheers,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
