Hello,
I've successfuly got flash as3 and Drupal talking, but I need to pass arguments to views.getview so that I can cut down on the amount of data transfered.
I'm using the following to connect, modified from the AMFPHP "hello world" example:
package {
import flash.net.NetConnection;
import flash.net.Responder;
import flash.net.URLRequest;
import flash.events.EventDispatcher;
import flash.events.Event;
public class ConnectToDrupal extends EventDispatcher{
private var gateway:String = "http:// mywebsitename /drupal/services/amfphp";
private var connection:NetConnection;
private var responder:Responder;
public function downLoad(viewName:String) {
// Responder to handle data returned from AMFPHP.
responder = new Responder(onResult, onFault);
connection = new NetConnection;
// Gateway.php url for NetConnection
connection.connect(gateway);
connection.call("views.getView", responder, viewName);
}
// Handle a successful AMF call.
public function onResult(result:Object) {
MenuGlobal.PAGES["temp"] = result;
// tell page to start populating itself
this.dispatchEvent(new Event(Event.COMPLETE));
}
// Handle an unsuccessfull AMF call.
public function onFault(fault:Object) {
// return fault;
}
}
}Which, when I call the downLoad method, is connecting fine, and making available to Flash a result object containing the view in question. What I need to do is cut down the result object using an argument that I pass to views.getView.
Presumably I need to add the argument to:
connection.call("views.getView", responder, viewName);
but I've tried:
connection.call("views.getView", responder, viewName, arg);
with no success. How do I do this?!

Calling views.getview and passing arguments
I used RemoteObject in Flex and was sucessful. Below is my commented code. Maybe you can adapt it
[Bindable]
public var pictures:Array ; // view loaded is a bunch of images
[Bindable]
public var all_view_arr:Array ;// list of views
[Bindable]
public var view_to_load:String ; // will use to pass name of view to load
public var views:RemoteObject ; // to load a specific view i.e. "views" service to call "views.getView"
public var allviews:RemoteObject ; // my own service to get all views, the name of service: "allviews"
public function init_allviews():void
{
allviews = new RemoteObject("amfphp") ;
allviews.source = "allviews" ;// my own drupal service
allviews.setRemoteCredentials("","") ;
allviews.addEventListener(ResultEvent.RESULT,onAllViewsResult) ;
allviews.addEventListener(FaultEvent.FAULT, onFault) ;
allviews.addEventListener(InvokeEvent.INVOKE, onInvoke) ;
}
public function init_views():void
{
view_to_load = "sspchillingout" ; // name of the view that I want to load
views = new RemoteObject("amfphp") ;
views.source = "views"; // the drupal views service name for loading views
views.addEventListener(ResultEvent.RESULT,onViewsResult) ;
views.addEventListener(FaultEvent.FAULT, onFault) ;
views.addEventListener(InvokeEvent.INVOKE, onInvoke) ;
}
public function init():void
{
// Alert.show("Calling init()", "Info") ;
init_views();
init_allviews();
getPictures() ;
getAllViews() ;
}
public function onViewsSelectionChanged(event:Event):void
{
//Alert.show(views_list_id.selectedItem.name,"Views Selection Changed to") ;
view_to_load = views_list_id.selectedItem.name ; // drop down combobox with other view names
}
public function onInvoke(event:InvokeEvent):void
{
//Alert.show("Invoking Remote Object", event.toString() ) ;
}
public function selectionChange(event:Event):void
{
pictID.source = dgID.selectedItem.images.preview ; // this is a Drupal Image
}
public function onFault(event:FaultEvent):void
{
Alert.show(event.fault.faultString,"Error") ;
}
public function onViewsResult(event:ResultEvent):void
{
//Alert.show("Picture list loaded from Drupal", "Info") ;
pictures = ArrayUtil.toArray(event.result) ; // return data(images) from drupal
}
public function onAllViewsResult(event:ResultEvent):void
{
//Alert.show("All view gotten from Drupal", "Info") ;
all_view_arr = ArrayUtil.toArray(event.result) ; // list of all views returned from Drupal
}
public function getAllViews():void
{ allviews.view();}
// below I call "views.getView" Drupal Service and passing parameters
public function getPictures():void
{
// Alert.show("calling views.getView for "+ view_to_load, "Info") ;
views.getView(view_to_load, ['nid','title','images']); // view_to_load contains name of view to load
}
That helped! Simply, I'd not
That helped!
Simply, I'd not been passing the arguments in the correct format. Looking at your code:
views.getView(view_to_load, ['nid','title','images']); // view_to_load contains name of view to loadI then tried editing my code to read:
var arrayOfArgs:Array = new Array('title','images');connection.call("views.getView", responder, viewName, arrayOfArgs)Passing arguments speeds up the data transfer by an incredible amount. I've gone from 2-4 seconds to load my images into a flash movie on the web down to almost instantaneous.
Thanks, DV
No problem!
I am glad that was helpful. I am still learning this stuff. I started at the begining of the year
a question please
what if I would want to pass an argument to the view that is inside of some other variable (i mean on something like dinamic_text.text). I ́ve tried many things but nothing works
thanks
