Re: [mapserver-users] total values from a shapefile?
Depends, are you talking about for labeling, expression evaluation or template display? For labeling: No. For expression evaluation: Yes (using logical expressions you can do EXPRESSION ([item1] + [item2] 50) For templates: Yes for HTML via javascript, e.g.: script ... var total = [item1] + [item2]; document.write(total); /script Steve On 4/28/2009 at 11:26 AM, in message 3d56274b4a7874468f58faddbfd09801073a3...@llmhs02.r8nssis.local, Mark Volz markv...@co.lyon.mn.us wrote: Hello, Can map server combine two fields and display a total for the values, or do we need to total the values ahead of time in the shapefile?

Even if it could, I would always pre-process the data, so MapServer doesn't have to execute those extra functions on-the-fly, and therefore speed up my application. -jeff -- Jeff McKenna FOSS4G Consulting and Training Services http://www.gatewaygeomatics.com/ ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
