[MAPSERVER-USERS] Pass parameters to mapfile

[thomas bonfort]

you'd use something like this:

* in your mapfile:
DATA "the_geom from ( select * from customised_point AS f where
user_id='%userid%' AND f.subcat_id IN (select subcat_id from subcat_info where
maincat_id =0))AS foo USING UNIQUE gid"

you can add a regular expression for validating the %userid% string
for your layer:
metadata
 userid_validation_pattern "[a-zA-Z]*"
end

* the the wms url should include a userid=foo in it:
wms[5] = new OpenLayers.Layer.WMS.Untiled("Customization",
"http://gis.rtbi-iitm.in/cgi-bin/mapserv?map=/var/www/html/customisation/mapfile/customNR.map"
{'layers': "NR_point",'transparent':"true", 'userid':'foo'},
{'isBaseLayer':false} );

note that openlayers capitalizes the url params, so you should
probably use %USERID% in your mapfile

cheers,
thomas
