[mapguide-users] how to use FDO api into MAPGUIDE applications

[Stefan Dalakov]

Rodolfo,
I don't dare to oppose Andy, I believe there is a solid justification 
behind his statements, but note that:
1. This post concerns the previous versions of MGOS and FDO (I do not 
say that it makes difference, in fact I am not aware of changes from FDO 
3.3.0 to 3.3.1)
2. Since Mapguide connects to data in an uniform manner - thru FDO,  and 
you are able to accomplish your task with SDF, then it depends only on 
capabilities of the FDO provider if you will succeed with SHP or any 
other format
I am sorry, if I have not been helpful to you

Ivan ,
I have used as a template the redlining module from PHPSAMPLES package.
Here is part of the code :

.........
    $map = new MgMap();
    $map->Open($resourceService, $mapName);
    $mylayers = $map->GetLayers() ;
    $mylayer = $mylayers->GetItem ($layerName);
    $ftrclassname = $mylayer->GetFeatureClassName();
    $batchPropertyCollection = new MgBatchPropertyCollection();
    $propertyCollection = MakePoly($use,$plabel,$owner, $polydef);
    $batchPropertyCollection->Add($propertyCollection);
    $cmd = new MgInsertFeatures( $ftrclassname, $batchPropertyCollection);
    $featureCommandCollection = new MgFeatureCommandCollection();
    $featureCommandCollection->Add($cmd);
    $featureService->UpdateFeatures 
($myResourceID,$featureCommandCollection,false);
.......

  function MakePoly($puse,$pplabel,$powner,$polystring)
  {
    $propertyCollection = new MgPropertyCollection();
    $ownerProperty = new MgStringProperty("Owner", $powner);
    $propertyCollection->Add($ownerProperty);
    $useProperty = new MgStringProperty("Purpose", $puse);
    $propertyCollection->Add($useProperty);
    $labelProperty = new MgStringProperty("Label", $pplabel);
    $propertyCollection->Add($labelProperty);
    $wktReaderWriter = new MgWktReaderWriter();
    $agfReaderWriter = new MgAgfReaderWriter();
    $agftext = $polystring ;
    $geometry = $wktReaderWriter->Read( $agftext);
    $geometryByteReader = $agfReaderWriter->Write($geometry);
    $geometryProperty = new MgGeometryProperty("Geometry", 
$geometryByteReader);
    $propertyCollection->Add($geometryProperty);
    return $propertyCollection;
  }

The coordinate data in $polystring is formatted according to the grammar 
described in

Best regards : Stefan
