Hi all.
I want to execute custom query on one layer using PHP. $mgSessionId and
$parcel_id are passed from another page and they are ok (I checked with
echo). Here's the code:
<?php
include 'constants.php';
$mgSessionId = $_GET['SESSION'];
$parcel_id = $_GET['parcel_id'];
try
{
MgInitializeWebTier("$../../webconfig.ini");
$userInfo = new MgUserInformation($mgSessionId);
$siteConnection = new MgSiteConnection();
$siteConnection->Open($userInfo);
$resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);
$featureService =
$siteConnection->CreateService(MgServiceType::FeatureService);
$map = new MgMap();
$mgMapName = 'map1';
$map->Open($resourceService, $mgMapName);
$queryOptions = new MgFeatureQueryOptions();
$queryOptions->SetFilter("parcel_id = $parcel_id");
$layer2 = $map->GetLayers()->GetItem('parcels');
$featureReader = $layer2->SelectFeatures($queryOptions);
}
?>
But this returns the following:
Null reference.Null reference. Exception occurred in method MgMap.GetService
at line 93 in file
d:\buildforgeprojects\mapguide_open_source_v2.0\build_23.8\mgdev\common\mapguidecommon\MapLayer/Map.cpp
What is wrong here?
