[mapserver-users] show only some point on the map

[valerio vianello]

Dear Till,

Thanks for the suggestion.

But with variable substitution I am able to specify only one parameter like

EXPRESSION ([FNR]=%myid%)
. 

in this case on the map will be shown only one point (if myid is unique) or a group of points (if myid is shared among them)

in my case I want show the points with myid1,myid2,myid3...

how I should set this into the mapfile ?

regards

Valerio

Dear Valerio,

I guess what you need is this:
http://mapserver.gis.umn.edu/docs/reference/mapfile/variable_sub

So add a variable substitution and insert it into your expression in the 
CALL section of your layer.
