Please update flash player to view this Flash ActionScript tutorial!

Flash Tutorial Content:

You can use Flash ActionScript to communicate with PHP files. A good practise is to get confirmation from the PHP file

The Flash Movie of this tutorial is shown as above.

PHP File Codes:


// $candidate is the variable send from Flash Actionscript
$candidate= $_POST['candidate'];

// Confirm to Flash ActionScript that the data has been received
echo "phpConfirm=Greeting " . $candidate . "! I received your data." ;


The output of the PHP file is "phpConfirm=Greeting Alex! I received your data".

Flash ActionScript Codes:

function checkComplete(evt:MouseEvent):void {

// Create A new URLVariables instance to store the variable
var myVariables:URLVariables = new URLVariables();

// Create a variable (e.g. candidate) to send
myVariables.candidate = "Alex";

// Create a new URLRequest instance sending data to "ascom01.php"
var myRequest:URLRequest = new URLRequest("ascom01.php");

// Send data using the POST method
myRequest.method = URLRequestMethod.POST;

// The data property of the request is set to the
// URLVariables instance (myVariables) to send to the PHP file.
// Note: myVariables stored the variable (e.g. candidate)
myRequest.data = myVariables;

// Create a new instance of the URLLoader class to work with.
// URLLoader.load( ) method should be used when we need the
// sent variables returned back to Flash ActionScript.
var myLoader:URLLoader = new URLLoader;

//specify dataFormat property of the URLLoader to be "VARIABLES"
//This ensure that the variables loaded into Flash with the same variable names
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;

//Load the PHP file by using URLRequest

//Listen when the loading of data COMPLETE
//Call the loadComplete function when the loading COMPLETE
myLoader.addEventListener(Event.COMPLETE, loadComplete);



// Hook up the button with the function checkComplete
enter_btn.addEventListener(MouseEvent.CLICK, checkComplete);

// This is the function that display the data returned back from PHP file
function loadComplete(evt:Event):void {

//Display the value with variable name "phpConfirm"
output_txt.text = evt.target.data.phpConfirm;
