[Cartoweb-users] Problem creating new layers

[Oliver Christen]

Hi

maybe try to enable the new layer after $result = $mapOverlay->updateMap($layer); :

$msLayer = $this->serverContext->getMapObj()->getLayer($result->layers[0]->index);
$msLayer->set('status', MS_ON);

regards
Oliver

  You're right! 

  Here is the code that tries to make visible a new layer (simulacionesGrupo):

      public function filterPostRequest(FilterRequestModifier $request) {
          $layerList = $request->getValue('layers');
          $layerList[] = 'simulacionesGrupo';
          $request->setValue('layers', $layerList); 
          $this->tempinfo = implode('--', $layerList);
      } 

  it is in the Client part of a plugin that implements FilterProvider.

  To create the layer:

      function initializeRequest($requ) {
          if ($requ) {
              $pluginManager = $this->serverContext->getPluginManager();

              if (empty($pluginManager->mapOverlay))
                  throw new CartoserverException("mapOverlay plugin not loaded, ");

              $mapOverlay = $pluginManager->mapOverlay;
              $layer = new LayerOverlay();
              $layer->name = "simulacionesGrupo";
              $layer->action = BasicOverlay::ACTION_INSERT;
              $layer->data = "raster/ozono.99.tif";
              $result = $mapOverlay->updateMap($layer);
          }
      }

  it is in the Server part of the same plugin that extends ClientResponderAdapter.

  Anyway, if the "simulacionesGrupo" layer is defined in the mapfile, and the line with ACTION_INSERT is not used in the last piece of code, and the next line is commented in 'layers.ini':
  ; mapInfo.initialMapStates.default.layers.simulacionesGrupo.selected = true

  it doesn't show up in the main map.

      Hi all!

      I'm using the 'mapOverlay' plugin in order to modify the layers of my project. It has worked well to modify existing layers, but when I try to insert a new one, it simply does nothing.

      Perhaps it is related to another problem I'm facing: I can only hide a layer with "FilterProvider". If I try to make visible a layer that is not set as visible by default in the "layers.ini" file, nothing happens...

      I hope someone could help!
      Thanks in advance!
