[Mapserver-users] Drawing groups with perlMapscript

[Lowell Filak]

I don't know of a 'group' object which is what I think your looking for here.
However you can emulate a group by selecting all layers then looping through each of them and retrieving the group name ($layer->{group}) then set the layers which belong to the group you wish to draw on.
You can also add/remove layers that belong to a group by changing the value of $layer->{group} which may be a simpler solution depending on what your trying to accomplish.
