[mapserver-users] PHP Mapscript - layer->queryByAttribute problem

[Worth Lutz]

Using MapServer 5.4.0:

I have two shapefile layers in NC State Plane system, one in ft and one in
meters.  The PROJECTION in the layers allows the map to be drawn correctly.

My problem occurs when trying to use PHP mapscript to queryByAttribute.  I
am locating NC counties from two different shapefiles.  Using the layer
which is the same projection at the map there is no problem.  Using the
other layer, the bounds of the query result appear to be in meters and not
ft.  Is this normal?  Do I have to make the conversion?

Using mapserver 5.4.0 

PHP mapscript:

  $ms = ms_newMapObj( $mapfile );
  $ms->setSize($mapVpWidth,$mapVpHeight);
  $groupnames = $ms->getAllGroupNames();
  for($i=0; $i < sizeof($layerNames); $i++) {
    if(in_array($layerNames[$i],$groupnames)) {
      $layerIndexes = $ms->getLayersIndexByGroup($layerNames[$i]);
      for($j=0; $j < sizeof($layerIndexes); $j++) {
        $layer = $ms->getLayer($layerIndexes[$j]);
        $layer->set("status", MS_ON);
      }   
    } else {
      $layer = $ms->getLayerByName($layerNames[$i]);
      $layer->set("status", MS_ON);
    }
  }

  $layer = $ms->getLayerByName($layername);
  $layer->set('status', MS_ON);
  $layer->queryByAttributes($attribute, $expression, MS_MULTIPLE);
  $numresults = $layer->getNumResults();
  if ($numresults < 1) {
    $err->msg = 'No results in '.$layername.' for '.$attribute.' =
'.$expression.'.';
    $error = true;
  } else {
    $result = $layer->getResult(0);
    $layer->open();
    $shapeObj = $layer->getFeature($result->shapeindex);
    $layer->close();
    $minx = $shapeObj->bounds->minx;
    $miny = $shapeObj->bounds->miny;
    $maxx = $shapeObj->bounds->maxx;
    $maxy = $shapeObj->bounds->maxy;
    $ms->setExtent( $minx, $miny, $maxx, $maxy );
    $img = $ms->drawquery();
    $tmpMapImg = $img->saveWebImage();
  }
