[Adriano Hantequeste Gomes]

Hi All,


I put this code end my application.php:



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

if ($http_form_vars["nome_b"])
         {
             $nombre = $http_form_vars["nome_b"];
             $oextent = $oMapSession->oMap->extent;
             $capa = $oMapSession->oMap->getLayerByname("Bairros");
			// ("Capa" is a Layer Object)
             $capa->queryByAttributes("NOME_BAIRR",$nome_b,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 - 300;
                 $nmaxx = $oextent->maxx + 300;
                 $nminy = $oextent->miny - 200;
                 $nmaxy = $oextent->maxy + 200; //  (My Map have a
extent = 600 x 400 pixels)
                 $oextent->setextent($nminx,$nminy,$nmaxx,$nmaxy);
       }

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

 }
