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

[Andy Morsell]

Yes, things may have changed since then and /or some of the issues can be
worked around.  The largest obstacle for us was the fact that we could not
create a new Shape file programmatically.  We ended up doing everything with
SDF files for that application.

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

Hi Stefan, you can add and delete features using mapguide API, however you
can't create non add fields to the SHPs.

Hello,
 
Can you post some sample code for that?

For sure you can modify SHP files with Mapguide API - I have application
 
which adds and deletes features.
I have not tried to create a SHP file, but I don't think it is
impossible

I have read that only SDFs can be created and altered with mapguide
API,
which is why I need to use FDO api in my mapguide applications in
order to
create and alter SHPs.
 
If anyone has code sample or documentation about it, I will be very
grateful.
 
Cheers,
