$id = $shape->values['ID']; _____ From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Medve Zsolt Sent: Thursday, April 01, 2010 10:44 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] GetFeatures - get the ID value of clicked shape Hy all Can someone help me with this? $layer = $map->getLayerByName('sde1','sde2','sde3','sde4'); // xy pix -> geo pt $xPixel = $_REQUEST['x']; $yPixel = $_REQUEST['y']; $xGeo = $_SESSION['GEOEXT']['minx'] + (($xPixel/$_SESSION['mapwidth']) * ($_SESSION['GEOEXT']['minx']-$_SESSION['GEOEXT']['maxx'])); $yGeo = $_SESSION['GEOEXT']['maxy'] - (($yPixel/$_SESSION['mapheight']) * ($_SESSION['GEOEXT']['maxy']-$_SESSION['GEOEXT']['miny'])); $pt = ms_newPointObj(); $pt->setXY($xGeo, $yGeo); // proj $mapProjStr = $map->getProjection(); $layerProjStr = $layer->getProjection(); if ($mapProjStr && $layerProjStr && $mapProjStr != $layerProjStr) { $mapProjObj = ms_newprojectionobj($mapProjStr); $layerProjObj = ms_newprojectionobj($layerProjStr); $pt->project($mapProjObj, $layerProjObj); } // set map extent and size: $map->setExtent($_SESSION['GEOEXT']['minx'], $_SESSION['GEOEXT']['miny'], $_SESSION['GEOEXT']['maxx'], $_SESSION['GEOEXT']['maxy']); $map->setSize($_SESSION['mapwidth'], $_SESSION['mapheight']); $map->preparequery(); // Use '@' to avoid warning if query found nothing @$layer->queryByPoint($pt, MS_SINGLE, -1); $pt->free(); if ($layer->getNumResults() == 1) { $res = $layer->getResult(0); $layer->open(); $shape = $layer->getFeature($res->shapeindex, $res->tileindex); $id = $shape->ID; $layer->close(); } This code gets the x and y coordinates of the clicking ($xPixel = $_REQUEST['x']) I have transformed it to Geo coords, and so on, and in the end i want to search for my clicked shape's ID Am i right that the $id variable is contaning the ID value of the clicked shape? i have bolded the line i talking about.. (The shape file have an attribute table and mine have a ID column) Please if someone can help , do it:P thanks, Zsolt
