Re: [mapserver-users] Parameterized MapFile using CGI variable
Yes. Just as you have suggested. Have a CGI wrapper script, which determines the variable's value based on hostname (or whatever), then append this (to the QUERY_STRING prior to executing mapserver. See: http://mapserver.org/cgi/wrapper.html As shown in the link below, both the CONNECTION & DATA strings in the mapfile are supported by the preprocessor for variable substitution. http://mapserver.org/mapfile/variable_sub.html Cheers, Brent Wood --- On Sat, 4/30/11, Nicolas BOUTET wrote: From: Nicolas BOUTET Subject: [mapserver-users] Parameterized MapFile using CGI variable To: mapserver-users@lists.osgeo.org Date: Saturday, April 30, 2011, 1:56 AM Dear All, I have 2 MapServer servers.

Re: [mapserver-users] Parameterized MapFile using CGI variable
Hi, No problem at all. I have it this way For each layer LAYER STATUS ON GROUP "default" PROJECTION "init=epsg:3067" END INCLUDE "/usr/map/connection_osm_i.map" maxscaledenom 500010 minscaledenom 250010 TYPE LINE NAME "roadsclose" DATA "way from (select way, osm_id ,highway,ref, name, tunnel from osm_line where highway is not null order by priority desc) as foo using unique osm_id using srid=3067" ... ... And the "/usr/map/connection_osm_i.map" file is CONNECTIONTYPE postgis CONNECTION "host=localhost dbname=xxx user=yyy password=zzz port=5432" PROCESSING "CLOSE_CONNECTION=DEFER" Helps a lot when changing something on the database side also because there is only one place to update in the mapfiles. -Jukka Rahkonen- -Alkuperäi nen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Nicolas BOUTET Lähetetty: pe 29.4.2011 17:49 Vastaanottaja: 'Fawcett, David (MPCA)'; mapserver-users@lists.osgeo.org Aihe: RE: [mapserver-users] Parameterized MapFile using CGI variable Thank you David, Yes, using INCLUDE should be a good solution.

As David stated, the INCLUDE keyword does not have to be a full mapserver object, it can be any valid mapserver keywords. -- thomas On Fri, Apr 29, 2011 at 16:49, Nicolas BOUTET wrote: > Thank you David, > > > > Yes, using INCLUDE should be a good solution.
