[mapserver-users] No points selected with queryByShape

[Lime, Steve D (MNIT)]

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 void
END

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;
    }
}
