[Cartoweb-users] Passing variable to mapserver

[Fabio D'Ovidio]

Ok Oliver....
My clientplugin now extend also ServerCall
like this:

/**
     * @see ServerCaller::buildRequest()
     */
    public function buildRequest() {
     
            $layer = new LayerOverlay();
            $layer->name = "mylayer";
            $layer->data = "the_geom from (SELECT *, 
geocodifica2.the_geom FROM servizi, geocodifica2 WHERE servizi.gid = 
geocodifica2.gid)" .
                       "AS foo USING UNIQUE gid USING SRID=4326";
            $layer->filter = "servizio_uno = 'Y'";   
       
      
    }


    /**
     * @see ServerCaller::initializeResult()
     */
    public function initializeResult($result) {}


    /**
     * @see ServerCaller::handleResult()
     */
    public function handleResult($result) {}



and server side something like this: ?

class ServerExampleRecentering extends ClientResponderAdapter {

    /**
     * @var Logger
     */
    private $log;

    /**
     * @var objet
     */
    private $layer;


    /**
     * Constructor
     */
    function __construct() {
        parent::__construct();
        $this->log =& LoggerManager::getLogger(__CLASS__);
    }


    /**
     * @see ClientResponder::initializeRequest()
     */
    function initializeRequest($requ) {
        if ($requ)
            $this->layer = $requ->layer;
    }



    /**
     * Result is set in initializeRequest but Outline must be called
     * in handlePreDrawing
     * @see ClientResponder::handlePreDrawing()
     */
    function handlePreDrawing($requ) {
        if ($requ) {
           
           
            $mapOverlay = $this->serverContext->getPluginManager()
            if (empty($pluginManager->mapOverlay))
                throw new CartoserverException("mapOverlay plugin not 
loaded, "
                                               . "and needed to draw the 
new layer");
            $mapOverlay->updateMap($this->layer);
        }
    }

}
