[mapguide-users] create a temporary !Mapdefinition and add a layer

[Arnaud De Groof]

Hi,

 

I have found my error. In fact, I used the command "SetRessource" with a WebLayout in place of a MapDefinition. Now the script seems ok.

 

How to load the WebLayout with the new MapDefinition (with the new layer) and not the MapDefinition coming from the library (without the new layer)?

 

 

New 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); 

 

// Insert the layer in the MapDefinition

   $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 MapDefinition

   $updatedXml = $mdDomDoc->saveXML();

   $byteSource = new MgByteSource($updatedXml, strlen($updatedXml));

 

// Create a new MapDefinition (session repository).

   $sessionMapName = $mdResourceId->GetName();

   $sessionMapDefinition = "Session:$sessionId//$sessionMapName.MapDefinition";

   $sessionResourceId = new MgResourceIdentifier($sessionMapDefinition);

 

// Write the updated MapDefinition

   $resourceService->SetResource($sessionResourceId, $byteSource->GetReader(), null);

 

// Test the new MapDefinition

   $mdtest = "Session:$sessionId///$mapName.MapDefinition";

   $mdResourceIdtest = new MgResourceIdentifier($mdtest);

   $mdReadertest = $resourceService->GetResourceContent($mdResourceIdtest);

   $mdXmltest = $mdReader2->ToString();

   $mdDomDoctest = DOMDocument::loadXML($mdXmltest);

 

// 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;

 

 

Thanks,

 

Arnaud De Groof

The previous error you had indicated that the xml was invalid.

This is likely because you are not sending the entire xml document to the server.
Perhaps someone with better PHP skills can help you out.

I have changed the line: "$byteSource = new MgByteSource($updatedXml, strlen($updatedXml));" by "$byteSource = new MgByteSource($updatedXml, mb_strlen($updatedXml));"  without success.

 

The xml code coming from the initial MapDefinition was carried out thanks to Maestro. I join here the result of the $updatedXml:
