[Mapserver-users] Query Question

[woodbri at swoodbridge.com]

Well there are really two parts to this question:

1) How to do the query of everything that is visible?
    A: set the bounding box of the query to the view extents
2) How to automatically do the query whenever the zoom scale is 
smaller than some number.
   A: I think you will have to do this in mapscript or using some 
javascript to initiate the query to post the results to another frame 
or window. You might be able to attach this action on you onLoad 
event handler for the page displaying the map.
