Hi, Presumably date.php contains some additional functions that use the ID of the selected feature to do something. The value the script is outputting corresponds to the feature ID. So if you pass that ID into the appropriate function, it will hopefully do something useful...

Hi Chris Thanks for your help. Now my date.php script is as below: <?php $mapName = ""; $sessionId = ""; $ID = ""; try { // Initialize the web tier API MgInitializeWebTier("C:\Program Files\MapGuideOpenSource2.0\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); $selectionXml = $selection->ToXml(); // Output the selection //echo $selection->ToXml(); echo $selectionXml; } catch(MgException $e) { // Output error details echo "<Message>" . $e->GetMessage() . "</Message>"; echo "<Details>" . $e->GetDetails() . "</Details>"; } function GetParameters($params) { global $mapName; global $sessionId; global $ID; $mapName = $params['MAPNAME']; $sessionId = $params['SESSION']; $ID = $params['ID']; } function GetRequestParameters() { if($_SERVER['REQUEST_METHOD'] == "POST") GetParameters($_POST); else GetParameters($_GET); } ?> The output of url & content was generated by date.php is as below: http://127.0.0.1:8008/mapguide/fusion/templates/mapguide/flr3/mapguide.php?LOCALE=en&SESSION=c9a91b36-ffff-ffff-8000-001c42ffa53c_en_7F0000010AFC0AFB0AFA&MAPNAME=Default49d05a9c7a129&ID=%24CurrentSelection <---- same the previous setting AQAAAAAAAAA= <---- it would be changed when the differ feature data was selected. This is the mapguide studio setting. Does it have anything wrong? Thanks Achectl Hi Achectl, It is encouraging that it got that far before it failed this time. In the code below, you've commented out the original call to get the selection from the map, and instead retrieve it from the $selectionXml parameter. I don't see this defined anywhere, which is presumably why it fails. Try changing this: // Retrieve the selection $selection = new MgSelection($map, $selectionXml); //$selection = new MgSelection(); //$selection->Open($resourceService, $mapName); To this: // Retrieve the selection $selection = new MgSelection(); $selection->Open($resourceService, $mapName); $selectionXml = $selection->ToXml(); Chris. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of achectl Sent: Thursday, March 26, 2009 3:33 AM To: [email protected] Subject: RE: [mapguide-users] What is %24CurrentSelection??? Hi Chris, I've tried to follow your script and try to modify a little of date.php as below: <?php $mapName = ""; $sessionId = ""; $ID = ""; $Area = ""; try { // Initialize the web tier API MgInitializeWebTier("C:\Program Files\MapGuideOpenSource2.0\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 $selection = new MgSelection($map, $selectionXml); //$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; global $ID; global $Area; $mapName = $params['MAPNAME']; $sessionId = $params['SESSION']; $ID = $params['ID']; $Area = $params['Area']; echo $mapName; echo $ID; echo $Area; } function GetRequestParameters() { if($_SERVER['REQUEST_METHOD'] == "POST") GetParameters($_POST); else GetParameters($_GET); } ?> After click the invokeURL command of the fusion layout, it prompts the error "Default49cb4916a1dfe$CurrentSelection$CurrentSelectionAn unclassified exception occurred.An unclassified exception occurred. Exception occurred in method new_MgSelection at line 12308 in file .\MgApi_wrap.cpp" of the new date.php window. The $ID & $Area is the key of the invokeURL.js. It seems that the proper value still can't to find! I think it should be something missing of the date.php. Thanks Achectl If your date.php file is on a separate server, it seems like a good idea to save the sample code in a local file, as you've done, and then make that script issue a subsequent request to date.php. It looks like the SESSION parameter is not getting sent to your script. It could be a case issue - it might get sent as lowercase 'session' instead. Are you able to use Fiddler or Firebug to determine which parameters are actually getting sent to your script? I also remember seeing a defect where the parameters got sent twice, which caused problems. If your InvokeUrl.js (in the fusion/widgets folder) contains a section like this: execute : function() { var url = this.sBaseUrl; //add in other parameters to the url here var map = this.getMap(); var params = []; params.push('LOCALE='+Fusion.locale); params.push('SESSION='+map.getSessionID()); params.push('MAPNAME='+map.getMapName()); params = params.concat(this.additionalParameters); try changing it to: execute : function() { var url = this.sBaseUrl; //add in other parameters to the url here var map = this.getMap(); var taskPaneTarget = Fusion.getWidgetById(this.sTarget); var params = []; if ( taskPaneTarget == null ) { params.push('LOCALE='+Fusion.locale); params.push('SESSION='+map.getSessionID()); params.push('MAPNAME='+map.getMapName()); } params = params.concat(this.additionalParameters); An alternative approach would be to fix the InvokeUrl.js file so that it handles the $CurrentSelection variable correctly, but that would require a bit of figuring out.
