Hi,

 

According to the codes samples
(http://trac.osgeo.org/mapguide/wiki/CodeSamples), I try to use the PHP
code samples to add a layer to the initial map. 

I carried out the below code but it seems that
"$resourceService->SetResource($sessionResourceId,
$byteSource->GetReader(), null);" encounters an error in the code.


<?php

include "../../mapviewerphp/constants.php";
include "../../mapviewerphp/common.php";
 
// Initialize
    MgInitializeWebTier($webconfigFilePath);
    $args = ($_SERVER['REQUEST_METHOD'] == "POST") ? $_POST : $_GET;
    $sessionId = $args['SESSION'];
    $mapName = $args['MAPNAME'];
    $layerName1 = 'YYY';
    
    $userInfo = new MgUserInformation($sessionId);
    $siteConnection = new MgSiteConnection();
    $siteConnection->Open($userInfo);
    $resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);
 
    $wl = "Library://XXX/XXX.WebLayout"; // TODO Constant!
 
// Build a string pointing to the new layer in the Session
    $rlLayerResourceId =
"Session:$sessionId//$layerName1.LayerDefinition";
 
// Read the XML of the Library Map Definition
   $md ="Library://XXX/$mapName.MapDefinition";
   $mdResourceId = new MgResourceIdentifier($md);  
   $mdReader = $resourceService->GetResourceContent($mdResourceId);
   $mdXml = $mdReader->ToString();
   $mdDomDoc = DOMDocument::loadXML($mdXml); 
 
// Create the MapLayer XML nodeset in the first position
   $targetNode = $mdDomDoc->getElementsByTagName("MapLayer")->item(0);
   $newNode = $targetNode->parentNode->insertBefore(new
DOMElement("MapLayer"), $targetNode); 
   $newNode->appendChild($mdDomDoc->createElement("Name", $layerName1));
   $newNode->appendChild($mdDomDoc->createElement("ResourceId",
$rlLayerResourceId));
   $newNode->appendChild($mdDomDoc->createElement("Selectable",
"false"));
   $newNode->appendChild($mdDomDoc->createElement("ShowInLegend",
"false"));
   $newNode->appendChild($mdDomDoc->createElement("LegendLabel"));
   $newNode->appendChild($mdDomDoc->createElement("ExpandInLegend",
"false"));
   $newNode->appendChild($mdDomDoc->createElement("Visible", "true"));
   $newNode->appendChild($mdDomDoc->createElement("Group"));
 
// Write the XML out to form the Session Map Definition
   $updatedXml = $mdDomDoc->saveXML();
   $byteSource = new MgByteSource($updatedXml, strlen($updatedXml));
 
// Create a web layout in the session to hold the updated version
// from the library.
   $sessionMapName = $mdResourceId->GetName();
   $sessionWebLayout = "Session:$sessionId//$sessionMapName.WebLayout";
   $sessionResourceId = new MgResourceIdentifier($sessionWebLayout);
 
// Write the updated web layout to the session.
   $resourceService->SetResource($sessionResourceId,
$byteSource->GetReader(), null);
 
// Redirect to the Ajax viewer pointing at the map at the desired
coordinates.
   $redirectTo =
"mapguide/mapviewerajax/?WEBLAYOUT=$sessionWebLayout&SESSION=$sessionId"
;
   $host = $_SERVER["HTTP_HOST"];
   $url = "http://$host/$redirectTo";
 
 
// Redirect!
   header("Location: $url");
   exit;
 
//Test
   $f = 'exemple.txt';
   $handle = fopen($f,"w");
   fwrite($handle, "test0: <".$sessionId.">\r\ntest1 :<".$wl.">\r\ntest2
:<".$rlLayerResourceId.">\r\ntest3 :<".$md.">\r\ntestxml
:<".$mdXml.">\r\ntest4 :<".$layerName1.">\r\ntestxml1
:<".$updatedXml.">\r\ntest6 :<".$sessionMapName.">\r\ntest5
:<".$sessionWebLayout.">\r\ntest6 :<".$host.">\r\ntest7
:<".$redirectTo.">");
   fclose($handle);

?>

Please would you like to help me to resolve the following issue?
 
Thanks,
