[mapserver-users] RE Dynamically extent and layer filter

[Dedy Fuadi]

Wow! Thank you very much Steven!

Finally I can display custom data from postgis with your links before.
I set like this for the mapfile :
VALIDATION

'tid' '^[0-9]{1}\,'

END
FILTER (id in (%tid%))

And this is nicely work for me. :D

Thank you,
regards.
