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.

Hi to all,
Any of you have an example about how to do a parameter substitution???
What I want is to change the FILTER statement in one of my mapfile
layers, but I don't know how to do it.
This is my layer's data and filter definition:
DATA "the_geom FROM temp"
FILTER "id_session=%id%"
What I want is to change the id valuedepending on some circunstances in
my application.
Thanks in advance.
Hans Castorp
