[OSGeo-Edu] Consultation mapguide to be send

Mon Jul 13 10:08:15 PDT 2015

Hello Mapguides List,

I am developing an aplication about vehicle tracking and i have beed
reading the MgOpenSourceDevGuide.pdf.

I need to draw the car image about location on the map but i don´t
understand how to do it.

Coul you help me with this please.

My code is the follow:

<html>

<body onLoad="OnPageLoad()">

<?php
function add_layer_definition_to_map($layerDefinition, $layerName,
$layerLegendLabel, $sessionId, $resourceService, $map)
// Adds the layer definition (XML) to the map.
// Returns the layer.
{
 echo "Iniciando metodo add_layer_definition_to_map...";
    global $schemaDirectory;

    // Validate the XML.
    $domDocument = new DOMDocument;
    $domDocument->loadXML($layerDefinition);

    // Save the new layer definition to the session repository
    $byteSource = new MgByteSource($layerDefinition,
strlen($layerDefinition));
echo "<br/> echo 111 <br/>";
    $byteSource->SetMimeType(MgMimeType::Xml);
echo "<br/> echo 2222 <br/>";
echo "session: ".$sessionId;
    $resourceID = new
MgResourceIdentifier("Session:$sessionId//$layerName.LayerDefinition");
echo "<br/> echo 3333 <br/>";
    $resourceService->SetResource($resourceID, $byteSource->GetReader(),
null);
echo "<br/> echo 4444 <br/>";
    $newLayer = add_layer_resource_to_map($resourceID, $resourceService,
$layerName, $layerLegendLabel, $map);
echo "<br/> echo 5555 <br/>";
    return $newLayer;
}

function add_layer_resource_to_map($layerResourceID, $resourceService,
$layerName, $layerLegendLabel, $map)
// Adds a layer defition (which can be stored either in the Library or a
session
// repository) to the map.
// Returns the layer.
{
    $newLayer = new MgLayer($layerResourceID, $resourceService);

    // Add the new layer to the map's layer collection
    $newLayer->SetName($layerName);
    $newLayer->SetVisible(true);
    $newLayer->SetLegendLabel($layerLegendLabel);
    $newLayer->SetDisplayInLegend(true);
$newLayer->SetDisplayInLegend(true);
    $layerCollection = $map->GetLayers();
    if (! $layerCollection->Contains($layerName) )
    {
        // Insert the new layer at position 0 so it is at the top
        // of the drawing order
        $layerCollection->Insert(0, $newLayer);
    }

    return $newLayer;
}
