[Mapserver-users] Point whitin polygon

[Eric Bridger]

Use:
$map->queryByPoint($click_pt,$mapscript::MS_MULTIPLE,0) to get all the
polygons.  Also may sure all your layers in the map file define a
TEMPLATE "fake.html", even if you are not using the template to display
your query results.

I'm not sure about your postgis question.
