[mapguide-users] What is %24CurrentSelection???

In a basic web layout, I'm pretty sure $CurrentSelection returns you the current selection in XML format. This corresponds to the string you get if you call ToXml() on an MgSelection object using the web tier API.
It appears that the flexible web layout code does not treat $CurrentSelection as a special case, and simply returns the URL-encoded version of variable name itself.
The solution is to get hold of the MgSelection object for the current map selection within the invoked PHP code. The following PHP code will dump out the selection XML. You should be able to extend it pretty easily to extract exactly what you need from the selection...
(Note that you may need to adjust the path to the webconfig.ini file in the call to MgInitializeWebTier)
Hope this helps,
Chris.
<?php
$mapName = "";
$sessionId = "";
try
{
// Initialize the web tier API
MgInitializeWebTier("C:/Program Files/Autodesk/MapGuideEnterprise2009/WebServerExtensions/www/webconfig.ini");
// Read the map name and session ID
GetRequestParameters();
// Create a site connection
$user = new MgUserInformation($sessionId);
$siteConnection = new MgSiteConnection();
$siteConnection->Open($user);
// Create a resource service instance
$resourceService = $siteConnection->CreateService(0);
// Retrieve the selection
$selection = new MgSelection();
$selection->Open($resourceService, $mapName);
// Output the selection
echo $selection->ToXml();
}
catch(MgException $e)
{
// Output error details
echo "<Message>" . $e->GetMessage() . "</Message>";
echo "<Details>" . $e->GetDetails() . "</Details>";
}
function GetParameters($params)
{
global $mapName;
global $sessionId;
$mapName = $params['MAPNAME'];
$sessionId = $params['SESSION'];
}
function GetRequestParameters()
{
if($_SERVER['REQUEST_METHOD'] == "POST")
GetParameters($_POST);
else
GetParameters($_GET);
}
?>

Subject: [mapguide-users] What is %24CurrentSelection???
I would like to delineate how I do the invokeURL command as below:
My system:
MapGuide 2009
PHP bundle option
Window XP Pro
MapGuide Studio 2009
http://n2.nabble.com/file/n2490302/1.jpg
1. I use Sheboygan demo data
2. create the invokeurl commands of flexible web layout
3. URL to invoke is http://127.0.0.1/date.php
4. Key is the ID; Value is $CurrentSelection
5. Layer is the Buildings (SDF)
http://n2.nabble.com/file/n2490302/2.jpg
1. Building selected
2. InvokeURL command highlighted
http://n2.nabble.com/file/n2490302/3.jpg
1. New window prompted
2. The url is http://127.0.0.1/date.php?ID=%24CurrentSelection
My question is why the ID value is %24CurrentSelection, it is not the ID of
the building layer attribute?
Or I have do wrong setting?
Notes: I have amended a little of invokeURL.js. I coped it as below:
