[mapserver-users] Get the nearest layer with mapscript...

[Paul james]

Hi David...
In my system the user SELECT the active layer (dropdown), and so he can
"query" it selecting a a area or a point ....

But, I´d like to take off that dropdown to select active layer... And when
user click on map to query, I figure out what layer was clicked and query
that...
