<p class=MsoNormal>hi all.....<br>
<br>
Anyone plzz help me to set the filter.I am
having a feature source with properties(pan_id,Name.,etc..).Now I
wanna select the polygon from the map having pan_id=ID.<br>
The ID will be entered from the task pane. Here is my code:<br>
<br>
<b>I copied it from dev guide..Then what is this this"SHPGEOM" in
setspatialfilter<br clear=all>
</b><br>
<br>
<br>
<?php<br>
include '../common/common.php';<br>
<br>
$args = ($_SERVER['REQUEST_METHOD']=="GET")?
$_GET: $_POST;<br>
<br>
$sessionId = $args['SESSION'];<br>
$mapName = $args['MAPNAME'];<br>
$ID= $_GET['PanId'];<br>
<br>
<br>
try<br>
{<br>
<br>
// Initialize the Web Extensions and connect to
the Server using<br>
// the Web Extensions session identifier stored
in PHP session state.<br>

MgUserInformation($sessionId );<br>
$siteConnection = new MgSiteConnection();<br>
$siteConnection->Open($userInfo);<br>

$map = new MgMap($siteConnection);<br>
$map->Open( $mapName );<br>
<br>
// Get the geometry for the boundaries of
District <br>
<br>
$districtQuery = new MgFeatureQueryOptions();<br>
<b>
$districtQuery->SetFilter("pan_id=$ID");</b><br>
<br>
$layer = $map->GetLayers()->GetItem(0);<br>
$featureReader =
$layer->SelectFeatures($districtQuery);<br>
$featureReader->ReadNext();<br>
$districtGeometryData = $featureReader-><br>
GetGeometry('Data');<br>
<br>
// Convert the AGF binary data to MgGeometry.<br>
<br>
$agfReaderWriter = new MgAgfReaderWriter();<br>
$districtGeometry = $agfReaderWriter->Read($districtGeometryData);<br>
<br>
// Create a filter to select the desired
features. Combine<br>
// a basic filter and a spatial filter.<br>
<br>
$queryOptions = new MgFeatureQueryOptions();<br>
$<b>queryOptions->SetFilter("pan_id=$ID");
<br>
$queryOptions->SetSpatialFilter('SHPGEOM',
$districtGeometry, MgFeatureSpatialOperations::Inside);<br>

// turn it into a selection, then save the
selection as XML.<br>

$selectionXml = $selection->ToXml();<br>
<br>
