[Cartoweb-users] how to refresh legendlayersaftermapoverlayoperation?

[gasdia73]

I had to copy most of the code in LayersInitProvider.php to succeed but
eventually it worked:

so in my server plugin i have :

public function handlePreDrawing($requ) {

    $this->buildLayer('tombe');
    $this->buildLayer('blocchi');    
    $this->buildLayer('settori');    
    
  }

function buildLayer is :

  private function buildLayer($sLayer){
    
    $color = new ColorOverlay();
    $color->setFromHex($this->colors[$sLayer]);
    $style = new StyleOverlay();
    $style->index = 0;
    $style->color = $color;
    $label = new LabelOverlay();
    $label->outlineColor = $color;
    $class = new ClassOverlay();
    $class->action = BasicOverlay::ACTION_UPDATE;
    $class->name = $sLayer;
    $class->styles = array($style);
    $class->label = $label;
    $layer = new LayerOverlay();
    $layer->name = $sLayer;
    $layer->classes = array($class);

    $mapOverlay = $this->serverContext->getPluginManager()->mapOverlay;
    $mapOverlay->updateMap($layer);
    
    //gas prova
    
    $msMapObj = $this->serverContext->getMapObj();
    $msLayer = $msMapObj->getLayerByName($sLayer);
    $layerid = $sLayer.'_class_0';
    
    $this->getClassIcon($layerid,$msMapObj,$msLayer,0);
    
    //$this->serverContext->getMapObj()->save('debug.map');
    
  }

and the functions called are taken from LayersInitProvider

thank you for your help!
