Question

I was hoping maybe someone could provide some insight on a problem I\'m having a tough time deciding how to solve.

I have a rather simple flash application users can

You could actually invoke an ExternalInterface command to populate a hiddenfield in your HTML coming from your SWF component.

if (ExternalInterface.available) 
{
  var js:String = "yourJavaScriptFunction";
  var valToPass:String;
  ExternalInterface.call(js(valToPass));
}

And in your HTML page, you write a javascript function:

<script language="javascript" type="text/javascript">
function yourJavaScriptFunction(valToPass)
{
  document.getElementById('yourHiddenField').value = valToPass;
}

And from the unload event fired up by your page, you can access the value which was passed from your SWF.

Take note that you can call the javascript function from your SWF as soon as you get the login credentials of your user.

Hope this helps.

You want to use a combination of URLRequest, URLVariables and URLLoader to do this. See the below.

var myData:URLRequest = new URLRequest("some.php");
myData.method = URLRequestMethod.POST;

var variables:URLVariables = new URLVariables();
variables.username = 'CREATED USERNAME';

myData.data = variables;

var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, dataOnLoad);
loader.load(myData);

function dataOnLoad(evt:Event){
    trace('Completed');
}

This would then call the 'some.php' file with your username stored in '$_POST['username']'. Your php script can then make an impression on the db linking that username to that session (however you want to do that).
