Query Object on Map

[Adriano Hantequeste Gomes]

Hi All,

I change the code:

// Adriano hantequeste Gomes - 11/jan/07
//
// Consulta Objeto
//
//

if ($http_form_vars["nome_b"]) {

        $bairro = $http_form_vars["nome_b"];
        $oextent = $oMapSession->oMap->extent;
        $capa = $oMapSession->oMap->getLayerByname("Bairros");
        // ("Capa" is a Layer Object)
        $capa->queryByAttributes("NOME_BAIRR",$bairro,MS_SINGLE);

        if ($capa->getNumResults() > 0)
        {
                echo "Encontrou";
                $oresult = $capa->getResult(0);
                // oresult is a ResultCacheMemberObj
<http://mapserver.gis.umn.edu/doc42/phpmapscript-class-guide.html#result>
                $capa->open();
                $oshape =
                $capa->getShape($oresult->tileindex,$oresult->shapeindex);
                $oextent = $oshape->bounds;
                $oshape->free();
                //New Extent to show
                $nminx = $oextent->minx - 350;
                $nmaxx = $oextent->maxx + 350;
                $nminy = $oextent->miny - 275;
                $nmaxy = $oextent->maxy + 275; //  (My Map have a  extent = 700 x 550 pixels)
                $oextent->setextent($nminx,$nminy,$nmaxx,$nmaxy);
        }

        $oMapNavigator->zoomRectangle($oextent->minx,$oextent->miny,$oextent->maxx,$oextent->maxy);

}



I find the record on shape but retry this error:

Encontrou

Adriano,

Add a TEMPLATE line to the layer you want to query. It doesn't have to
point to a valid template, it just needs to be present for the layer
to be queryable.
