[mapserver-users] No points selected with queryByShape

Not sure I follow this.
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?

Is your feature layer queryable? That is, does is have a value set for TEMPLATE? Even ‘TEMPLATE void’ will do.

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;

    }

}
