That makes perfect sense. One thing I would like work on is improving mapserver's documentation... (which I may try to write once I understand it more)... Not so much on specific pieces of syntax, but more on the thinking and theory of how to put use and combine multiple features together to put applications together.
Thanks again. --John Jackson --Deputy Auditor --Franklin County Ohio From: Lime, Steve D (DNR) [mailto:steve.l...@state.mn.us] Sent: Monday, November 29, 2010 4:02 PM To: Jackson, John; mapserver-users@lists.osgeo.org Subject: RE: shpxy example Hi John: The ids variable is used to perform a runtime substitution. It's not a MapServer specific variable, just something I used in that particular example. In the mapfile here's the county layer: LAYER NAME county STATUS OFF DATA "data/bdry_counpy2_gen500" TYPE POLYGON CLASS EXPRESSION ('[COUN]' in '%ids%') STYLE COLOR "#BD9E5D" # "#A27528" OUTLINECOLOR 50 50 50 END END CLASS COLOR 255 255 255 OUTLINECOLOR 50 50 50 END TEMPLATE "templates/county_example.html" END The value for the CGI variable ids is substituted into the first class expression at runtime. So, if ids=1,2,3,4,5 then the class expression becomes ('[COUN]' in '1,2,3,4,5'). Ideally one should set a validation pattern for the ids variable to limit it's possible values. So, once the expression is changed if the attribute COUN is in the list of ids then we draw with the pukey brown, if not, then draw white. Does this help?

The part I don't understand how to get the map working in map mode. I'm not understanding the "ids" variable that is getting passed to mapserver. Are the id's a field in the data set? I don't see any documentation for it anywhere, and when I pass it, I just get my map back without anything selected. Again, thanks in advance for your help. Hope everyone had a wonderful thanksgiving. --John Jackson --Deputy Auditor --Franklin County Ohio
