[mapguide-users] Modify the map definition and web layout flexible definition of a session

[Gordon Luckett]

Using PHP (sorry my default code)

I can get the MapDefinition (from a simple InvokeURL widget - note the
lower-case mapname and session)

<?php
$configFilePath = "C:\Program Files\OSGeo\MapGuide\Web\www\webconfig.ini";

$session = urldecode($_REQUEST["session"]);
$mapName = urldecode($_REQUEST["mapname"]);

MgInitializeWebTier($configFilePath);


$userInfo = new MgUserInformation($session);

$siteConnection = new MgSiteConnection();
$siteConnection->Open($userInfo);

$featureService = $siteConnection->CreateService(2);

$resourceService = $siteConnection->CreateService(0);


$map = new MgMap($siteConnection);

$map->Open($mapName);

$mapDef = $map->GetMapDefinition();

echo $mapDef->ToString();

$reader = $resourceService->GetResourceContent($mapDef);

echo $reader->ToString();

?>
