[mapguide-users] How to get selected area information in mapguide

[nekad]

i have included constants.php

and there is no problem with MgServiceType anymore...

but, now i got the problem in finding the information of selected area...

when i run this code
$selection = new MgSelection($map, $_POST['SELECTION']); 
$layers = $selection->GetLayers();

it returns nothing, seems like i don't select any area on the map?
can you help me?
