Password protected content in Flash with ActionScript 3 and PHP

This morning I was browsing through the gotoAndLearn forum and I saw a question about how to make a password protected section in a Flash site. So, I made a quick example and I thought I should share it with all my readers too 😉

You can download the source files from here:

Here you can see the ActionScript 3 code:

stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.showDefaultContextMenu = false;

//path to the php file on your server
var phpPath:String = "login.php";

//make password text field (when you type the characters will be like "******")
pass.displayAsPassword = true;

login.addEventListener(MouseEvent.MOUSE_DOWN, loginDown);

function loginDown(e:MouseEvent):void{
	//check to see if something in both the user and pass text fields
	if (user.text != "" && pass.text != "") {
		sendLoadData();
	}else{
		trace("Please fill in both username and password");
	}
}
stop();

function sendLoadData():void
{
	var dataRequest:URLRequest = new URLRequest(phpPath);
	dataRequest.method = URLRequestMethod.POST;				

	// define the custom parameters that will be sent to the .php file
	var params:URLVariables = new URLVariables();
	params.user = user.text;
	params.pass = pass.text;

	dataRequest.data = params;

	var urlLoader:URLLoader = new URLLoader();
	urlLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
	urlLoader.addEventListener(Event.COMPLETE, urlLoaderComplete);

	try
	{
		urlLoader.load(dataRequest);
	}
	catch (event:Error)
	{
		trace("Incorrect PHP file path.");
	}
}

function urlLoaderComplete(event:Event):void
{
	// once all the data has been sent and we'll check for a message sent
	// from the php file to tell us if the operation has ended with success or not
	errorHandler(event.target.data.secure_response);
}

function errorHandler(message:Number):void
{
	// check the message that was sent back from the php file
	//trace(message)
	if (message == 1)
	{
		gotoAndStop(2);
	}
	else
	{
		trace("Wrong Username or Password");
	}
}

And here you have the PHP code:
