A layer must be queryable and ON before you can run query operations on it. That is:
LAYER NAME 'business_point_locations' STATUS ON # or DEFAULT TYPE POINT ...

Template is an empty layer in my map file we use to add shapes to for display. My Feature layer is a shapefile of business point locations. What does queryable mean in relation to a shapefile of points? Michael McInnis 6033 44th Ave. N.E.

That is, does is have a value set for TEMPLATE? Even ‘TEMPLATE void’ will do. Steve From: [email protected] [mailto:[email protected]] On Behalf Of Michael McInnis Sent: Tuesday, September 17, 2013 4:51 PM To: [email protected] Subject: [mapserver-users] No points selected with queryByShape I'm baffled on this one! I get a shape object $circle and I have a point layer $bizLayer. I know they are both valid as they overlay as expected on my map. When I call printBusiness to use queryByShape to get the points in the shape it always returns 0 for $numResults. Am I missing a step somewhere? // Get shape from point and radius $circle = createCircle($latlonPoint,$radius); echo 'Biz Count : '; $bizCount = printBusiness($bizLayer,$circle); echo $bizCount; // Draw all the layers per basic1.map $image=$map->draw(); // Draw circle - reads shp->draw(map,template,image); $circle->draw($map,$emptyLayer,$image); $image_url=$image->saveWebImage(); function printBusiness($featureLayer,$shp){ $featureLayer->queryByShape($shp); $numResults = $featureLayer->getNumResults(); if($numResults > 0){ echo 'if'; return $numResults; }else{ echo 'else'; return 0; } }
