[mapguide-users] Modify the PHPViewerSample

[Michael L.]

Hi,

i'd like to modify the query from the phpviewersample that the user can only
select the layer properties which are shown in the properties pane. What do
I have to change in this code to do this?

Thanks in advance

Michael

 function GetLayerProperties()
    {
        $properties = array();

		$resourceService =
$this->site->CreateService(MgServiceType::ResourceService);

		$map = new MgMap();
		$map->Open($resourceService, $this->args['MAPNAME']);
        $layer = $map->GetLayers()->GetItem($this->args['LAYERNAME']);

		$featureService =
$this->site->CreateService(MgServiceType::FeatureService);
        $resId = new MgResourceIdentifier($layer->GetFeatureSourceId());
        $schemaClass = explode(':', $layer->GetFeatureClassName());

        $classDef = $featureService->GetClassDefinition($resId,
$schemaClass[0], $schemaClass[1]);

        for ($i = 0; $i < $classDef->GetProperties()->GetCount(); $i++)
        {
            $propertyDef = $classDef->GetProperties()->GetItem($i);

            if ($propertyDef->GetPropertyType() ==
MgFeaturePropertyType::DataProperty)
            {
				$dataType = $propertyDef->GetDataType();
				if ($this->IsValidDataType($dataType))
				{
	                array_push($properties, new
Property($propertyDef->GetName(), $dataType == MgPropertyType::String));
				}
            }
        }
        return $properties;
    }
