wordpress flash API – sample code – Part 2

This post is part two of the AMF/PHP connector class that I started in a previous thread talking about the PHP part

now.. we go to flash. The first class is the DataConnector which establishes the connection to the AMF/PHP connector and calls the function
we declare a variable called callTitle which is assigned based on which function we’re calling. this variable is then used to decide what action to do in the event listener.

package data
{
	import events.Communicator;

	import flash.events.*;
	import flash.net.NetConnection;
	import flash.net.Responder;

	public class DataConnector extends EventDispatcher
	{

		private var gateway			:String ;
		private var callTitle		        :String = "";
		private var connection		:NetConnection;
		private var responder		:Responder;

		public function DataConnector()
		{

			gateway	= "./connectors/gateway.php";

			responder = new Responder(onResult, onFault);
			connection = new NetConnection;
			connection.connect(gateway);
		}

		public function getCategoryList(parentCatName:String = ""):void
		{
			callTitle = "getCategoryList";
			parentCategory = parentCatName;
			connection.call("functions.getCategoryList", responder , parentCatName);
		}
		public function getCategoryPosts(_catName:String = ""):void
		{
			callTitle = "getCategoryPosts";
			catName = _catName;
			connection.call("functions.getCategoryPosts", responder , catName);
		}

		public function getPostList():void
		{
			callTitle = "getPostList";
			connection.call("functions.getPostList", responder);
		}

		public function getPost(id:String):void
		{
			callTitle = "getPost";
			postID = id;
			connection.call("functions.getPost", responder , postID);
		}

		private function onResult(result:Object):void
		{
			switch (callTitle)
			{
			 case "getCategoryList":
			 	result = result as Array;
			 	var _cat:Array = new Array();
			 	for (var i:int=0; i <result.length; i++)
				{
					var _obj:Object = new Object();
					_obj.id 	= result[i].id ;
					_obj.title 	= result[i].title ;
					_obj.desc	= result[i].description;
					cat.push(obj)
				}
				// now do something with that array
			 break;

			 case "getPostList":
			 	result = result as Array;
			 	var _cat:Array = new Array();
			 	for (var i:int=0; i<result.length; i++)
				{
					var _obj:Object = new Object();
					_obj.id 	= result[i].id ;
					_obj.title 	= result[i].title ;
					cat.push(obj)
				}
				// now do something with that array
			 break;

			 case "getCategoryPosts":
			        result = result as Array;
			 	var _cat:Array = new Array();
			 	for (var i:int=0; i<result.length; i++)
				{
					var _obj:Object = new Object();
					_obj.index= result[i].index ;
					_obj.id 	= result[i].id ;
					_obj.title 	= result[i].title ;
					cat.push(obj)
				}
				// now do something with that array
			break;

			case "getPost":
			 	result = result as Object;
				// do something with the object
				// like trace(result.post.title) , trace(result.post.content) , trace(result.post.date)
				// and:
				// for (var i:int=0; i< result.meta.length; i++)
				// {
				//       trace(result.meta[i].index , " : " , result.meta[i].value);
				// }
			 break;

		         }
		}

		private function onFault(fault:Object):void
		{
			trace(String(fault.description));
		}
	}
}

This class can now be called from the parent class (Main for example) in the following fashion:

package
{
	import data.DataConnector;
	import flash.display.Sprite;
	import flash.events.*;

	public class Main extends Sprite
	{
		private var _dataConnector  ataConnector;

               public function Main()
		{
			_dataConnector = new DataConnector();
			_dataConnector.getCategoryList("cat1");
		}
         }
}

the way I usually do its is follow this sequence:
Main -> DataConnector -> call Function
DataConnector ->receive Call result and handle Data
DataConnector -> Dispatch Event with the handled Data
Main -> receive the event in an event listener -> use the data.

but again, this sequence is very dependant on the structure of your classes and projects.. so now you’re on your own…

hope this was helpful enough
