[Geomoose-users] Zoom To Selected

[Jeffrey Schmitz]

A rather late response, but this should be helpful on this topic. I reworked
the query php so that geomoose will zoom to a bounding box of all of the
search results of a query. In  your query.php file replace the

for($rx = 0; $rx < $numResults; $rx++) {
}

loop with:

for($rx = 0; $rx < $numResults; $rx++) {
                    $res = $queryLayer->getResult($rx);
                    $aRes = $queryLayer->getFeature($res->shapeindex);
                    $abounds = $aRes->bounds;
                    if($rx == 0){
                    $theMinX = $abounds->minx;
                    $theMaxX = $abounds->maxx;
                    $theMinY = $abounds->miny;
                    $theMaxY = $abounds->maxy;
                    }
                    if($theMinX > $abounds->minx){
                    $theMinX = $abounds->minx;
                    }
                    if($theMaxX < $abounds->maxx){
                    $theMaxX = $abounds->maxx;
                    }
                    if($theMinY > $abounds->miny){
                    $theMinY = $abounds->miny;
                    }
                    if($theMaxY < $abounds->maxy){
                    $theMaxY = $abounds->maxy;
                    }
                    array_push($resultFeatures, $aRes);
                    }

then replace

if(($totalResults == 1 and $firstResult != false) or ($totalResults >= 1 and
$zoomToFirst == true)) {
        $bounds = $firstResult->bounds;
        printf('GeoMOOSE.zoomToExtent(%f,%f,%f,%f);', $bounds->minx,
$bounds->miny, $bounds->maxx, $bounds->maxy);
    }

with

if($totalResults > 0){
    printf('GeoMOOSE.zoomToExtent(%f,%f,%f,%f);', $theMinX, $theMinY,
$theMaxX, $theMaxY);
    }

Finally, place these lines

$theMinX = null;
$theMaxX = null;
$theMinY = null;
$theMaxY = null;

just above the line

for($la = 0; $la < sizeof($query_layers); $la++) {


This should allow the zoom to be adjusted to the maximum bounds of your
search results. Best of luck! Feel free to ask any questions.
