[mapguide-users] Re: Passing coordinates with invoke url

[Mauricio Villablanca]

"I want to click the map to fetch the coordinates regardless of layers and
features."

So you need the map's coordinate system?

Here's how to do it in PHP:
		
		MgInitializeWebTier ($configFilePath);
		$sessionId = $_POST["SESSION"];
		$mapName = $_POST["MAPNAME"];
		
		$userInfo = new MgUserInformation($sessionId);
		$siteConnection = new MgSiteConnection();
		$siteConnection->Open($userInfo);
		
		$resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);
		$featureService =
$siteConnection->CreateService(MgServiceType::FeatureService);
		
		$map = new MgMap();
		$map->Open($resourceService, $mapName); //map is in the viewer
		$srs = $map->GetMapSRS();
