[MAPSERVER-USERS] runtime variable substitution

[Yewondwossen Assefa]

Hi There,

There are a couple of examples at the end of 
http://mapserver.gis.umn.edu/docs/reference/mapfile/variable_sub/

You should be able in your case to use a URL like 
....&id=value_of_the_id . Have you tried this and It did not work?

Hope it helps.

Y.A.
