sending variable value from php to flash to load an xml file

[sukha]

I would like to load an XML file from the location locally or on the server being unaware of the name of the file. I am using PHP for sending the filename to Flash.

The below is the PHP code:

<?php

filesInDir('C:\Documents and Settings\457305\My Documents\shrikant\Flash Tutorials\webassist');

function filesInDir($tdir)

{

        $dirs = scandir($tdir);

        foreach($dirs as $file)

        {

                if (($file == '.')||($file == '..'))

                {

                }

                elseif (is_dir($tdir.'/'.$file))

                {

                        filesInDir($tdir.'/'.$file);

                }

                else

                {

                        echo "fileName=$file";

                }

        }

}

?>

And below is the loading Actionscript code:

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.events.Event;

import flash.net.URLVariables;

stop();

// Define the PHP file to be loaded

var phpFile:String = "http://localhost/webassist/test.php";

var cons_xml:XML;

var xmlLoader:URLLoader = new URLLoader();

// Specify dataFormat property of the URLLoader to be "VARIABLES"

// This ensures variables loaded into Flash with same variable names

xmlLoader.dataFormat = URLLoaderDataFormat.VARIABLES;

xmlLoader.load(new URLRequest(phpFile));

xmlLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(evt:Event):void

{

          trace(evt.target.data.fileName);

          //cons_xml = new XML(evt.target.data.fileName);

          //gotoAndPlay(2);

}

When I trace the evt.target.data it displays "fileName=mainOpenEndedXML%2Exml" and when I trace evt.target.data.fileName the fileName is properly displayed as "mainOpenEndedXML.xml".

But in the next two lines where the loading occurs it does not load the file i.e the swf file from xml doesn't play.

I have been searching the Internet for answers but not able to find any solutions.

The loading works properly if i directly insert the xml file in the code and the swf's in the XML file play propertly. The below is the code for the same:

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.events.Event;

import flash.net.URLVariables;

stop();

var cons_xml:XML;

var xmlLoader:URLLoader = new URLLoader();

xmlLoader.load(new URLRequest("mainOpenEndedXML.xml"));

xmlLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(evt:Event):void

{

          cons_xml = new XML(evt.target.data);

          gotoAndPlay(2);

}

Any help on this would be greatly appreciated

You said you are using PHP to send the file name to Flash.  If the php file is only providing you with the name of the xml file that you need to load, then you still need to load the xml file in a similar manner as you show in your last set of code where you say you load it directly.

I need to pull the filename dynamically via PHP and include it in the below code

xmlLoader.load(new URLRequest("mainOpenEndedXML.xml"));

as the name of the xml file will be different each time but the file will be saved in the same location.

Yes. you already said that, but I guess you don't understand what I said.  You are loading the PHP fle to get the filename, but nowhere are you taking that filename and loading the file that was named. 

You need to do two loading operations.  The first one to get the filename, and the second to load the file with that name.  Maybe if you name the PHP file loader phpLoader instead of xmlLoader it will start to make more sense to you.  Something like the following...

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.events.Event;

import flash.net.URLVariables;

stop();

// Define the PHP file to be loaded

var phpFile:String = "http://localhost/webassist/test.php";

var phpLoader:URLLoader = new URLLoader();

// Specify dataFormat property of the URLLoader to be "VARIABLES"

// This ensures variables loaded into Flash with same variable names

phpLoader.dataFormat = URLLoaderDataFormat.VARIABLES;

phpLoader.load(new URLRequest(phpFile));

phpLoader.addEventListener(Event.COMPLETE, processPHP);

function processPHP(evt:Event):void

{

         var xmlLoader:URLLoader = new URLLoader();

         xmlLoader.load(new URLRequest(String(evt.target.data.fileName)));

         xmlLoader.addEventListener(Event.COMPLETE, processXML);

}

var cons_xml:XML;

function processXML(evt:Event):void

{

          cons_xml = new XML(evt.target.data);

          gotoAndPlay(2);

}

Thanks a ton. That really helped solve the problem
