[mapserver-users] Expressions

I have a mapsource in an .xml file that calls the map file



  <map-source name="Burglaries" type="mapserver">

    <file>./maple_grove_datasets/police/Burglaries.map</file>

    <param type="today" offset="-7" name="LASTWEEK" format="%4Y%2M%2D" />

    <param type="today" offset="-14" name="LASTTWOWEEKS" format="%4Y%2M%2D" />

    <param type="today" offset="-30" name="LASTTHIRTY" format="%4Y%2M%2D" />

    <param type="today" offset="-90" name="LASTNINTY" format="%4Y%2M%2D" />

    <layer name="Burglaries"/>

  </map-source>



In the map file the EXPRESSION is handled



That what you are talking about?

How are you calling mapserver directly?

You need to do something like:



http://host/cgi-bin/mapserv?.....&LASTTWOWEEKS=100916
