[Guest]

Hi im currently creating a database search using XML,PHP and AS3, I have a number of products which i need to retrive the name and product id.

It is all being added to a list in flash. The items are being added to the list but its not showing any text in the list.

Any help is greatly appreciated.

import fl.data.DataProvider;

import flash.events.MouseEvent;

var allProdbase:Array = [];// contains all products like in xml

var currentProdbase:Array = [];// contains products that need to be displayed

var _loader:URLLoader = new URLLoader();

var _data:XML = new XML();

_loader.addEventListener(Event.COMPLETE, readXML);

_loader.load(new URLRequest("http://anonadd.com/product.xml"));

function readXML(event:Event):void

{

          _data = new XML(event.target.data);

          for each (var prod in _data.product)

          {

                    allProdbase.push({id: prod.@id, name: prod.@productname});

          }

          currentProdbase = allProdbase.concat();

          updateList();

}

function updateList():void

{

          productList.dataProvider = new DataProvider ();

          for (var i:int = 0; i<currentProdbase.length; i++)

          {

                    productList.addItem({label:currentProdbase.productname , label:currentProdbase.id});

          }

}

function traceName(e:MouseEvent):void

{

trace(e.target.name);

Make a

var dp:DataProvider = new DataProvider();

in the beginning, then later...

function updateList():void

{

          for (var i:int = 0; i<currentProdbase.length; i++)

          {

                    dp.addItem({label:currentProdbase.productname , label:currentProdbase.id});

          }

        productList.dataProvider = dp;

}

Hi mocca thanks for the reply,

I inserted your code

[AS]

import fl.data.DataProvider;

import flash.events.MouseEvent;

var allProdbase:Array = [];// contains all products like in xml

var currentProdbase:Array = [];// contains products that need to be displayed

var _loader:URLLoader = new URLLoader();

var _data:XML = new XML();

var dp:DataProvider = new DataProvider ();

_loader.addEventListener(Event.COMPLETE, readXML);

_loader.load(new URLRequest("http://shane.hailstormcommerce.com/product.xml"));

function readXML(event:Event):void

{

          _data = new XML(event.target.data);

          for each (var prod in _data.product)

          {

                    allProdbase.push({id: prod.@id, name: prod.@productname});

          }

          currentProdbase = allProdbase.concat();

          updateList();

}

function updateList():void

{

          productList.dataProvider = new DataProvider ();

          for (var i:int = 0; i<currentProdbase.length; i++)

          {

                    dp.addItem({label:currentProdbase.name , label:currentProdbase.id});

          }

          productList.dataProvider = dp;

}

productList.addEventListener(MouseEvent.MOUSE_UP, traceName);

function traceName(e:MouseEvent):void

{

          trace(productList.length);

}

[/AS]

But its still not showing th text.

[moccamaximum · Accepted solution]

remove the @ signs from your line

allProdbase.push({id: prod.@id, name: prod.@productname});

@-sign is reserved for Attributes (<product id=""/>)

in your xml id is an element not an attribute

(<product><id/></product>)

Thanks very much Mocca

The product id is not showing though just productname.

Could you also help with this?

[moccamaximum]

you are using the same identifier two times in one datagrid row ("label") the second one will therefore not be processed.

Write instead of:

dp.addItem({label:currentProdbase.name , label:currentProdbase.id});

something like this:

dp.addItem({prodname:currentProdbase.name , id:currentProdbase.id});

Just put a trace on the allProdbase array and it doesnt seem to contain the id.... So the problem must be here?

function readXML(event:Event):void

{

          _data = new XML(event.target.data);

          for each (var prod in _data.product)

          {

                    allProdbase.push({id: prod.id , name: prod.productname});

          }

          currentProdbase = allProdbase.concat();

          trace(allProdbase.length);

          updateList();

}

Syntax check of your xml gives me  errors:

iPhone</ productname> should be iPhone</productname> (without space in front of productname)

make sure you got all your tags right

[Guest]

It doesnt have any errors on my side, its created with php.

[moccamaximum]

If you are sure your xml is valid, check why you fail to retrieve the information you want.

Basics how to extract data from valid xml files with AS3 can be found here.

Ok thanks for your help again mocca
