// create two new instances of LoadVars, one to send and one to receive data var dataOut:LoadVars = new LoadVars(); var dataIn:LoadVars = new LoadVars(); // define what should happen when the response is received, // using 'this' to refer to dataIn and get data from it dataIn.onLoad = function() { if (this.valid=="1") { msg.text = 'Welcome. ' ; } else { msg.text = 'Sorry'; } } // the function that will be called by the Enter button function checkUser():Void { dataOut.username = username.text; dataOut.password = password.text; dataOut.sendAndLoad("check.php", dataIn, "POST"); } // define the behavior of the Enter button enterbtn.addEventListener("click", checkUser);PHP and flash
An example showing flash communicating with php and then back again to flash. Actionscript 3.0 used.

And the php file
check.php
<? $users = array( 'iamthwee' => 'password', 'IIIIIamthwee' => 'password', 'Immthwee' => 'password'); $found = false; foreach($users as $un => $pw) { if ($_POST['username']==$un && $_POST['password']==$pw) { $found = true; break; } } if (!$found) echo '&valid=0&'; ?>Flash, the echo string is made up of variable=value pairs, surrounded by &s. Flash itself will format this returned data for display, within the LoadVars onLoad routine.

^Scrap all the above. It's not actionscript 3.0 That'll teach me to debug it first.
OK
function completeHandler(evt:Event) { var username = evt.target.data.username; //var email = evt.target.data.email; msg.text = username; } enterbtn.addEventListener(MouseEvent.CLICK, clickMe); function clickMe(evt:MouseEvent):void { var request:URLRequest = new URLRequest("check.php"); request.method = URLRequestMethod.GET; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.VARIABLES; loader.addEventListener(Event.COMPLETE, completeHandler); loader.load(request); }check.php
<?php $returnVars = array(); $returnVars['username'] = "John Doe"; $returnVars['email'] = "johndoe@hotmail.com"; //send variables back to Flash echo 'username=iamthwee' ?>iamthwee
A quick example demonstrating the reverse flash -> php
var myData:URLRequest = new URLRequest("some.php"); myData.method = URLRequestMethod.POST; var variables:URLVariables = new URLVariables(); variables.title = "Hi friends"; variables.comments = 5; variables.image = "joke"; 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(loader.data.status) //status is a custom flag passed from back-end }some.php
<?php //Capture data from $_POST array $title = $_POST['Title']; $comments = $_POST['Comments']; $image = $_POST['Image']; echo $title; ?>iamthwee
A more useful example...
Of sending variables to flash, querying the database and then DISPLAYING the RESULT back in flash.
Flash file
btnOK.addEventListener(MouseEvent.CLICK, clickMe); //btnnext.addEventListener(MouseEvent.CLICK, clickMe2); function clickMe(evt:MouseEvent):void { var myData:URLRequest = new URLRequest("some.php"); myData.method = URLRequestMethod.POST; var variables:URLVariables = new URLVariables(); variables.name = usertxt.text; variables.password = passwordtxt.text; myData.data = variables; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.VARIABLES; loader.addEventListener(Event.COMPLETE, dataOnLoad); loader.load(myData); } function dataOnLoad(evt:Event) { label1.text = evt.target.data.user; }php file
<?php //Capture data from $_POST array $name = $_POST['name']; $password = $_POST['password']; $conn = mysql_connect("localhost","tonic6","password"); mysql_select_db("tonic6_test",$conn); $sql = "SELECT password FROM user where name ='".$name ."'"; $result = mysql_query($sql,$conn); $pass = ""; while($newArray = mysql_fetch_array($result)) { //give name to the fields $pass = $newArray['password']; } if ($pass == $password) { echo "user=1"; } else echo "user=0"; ?> Be a part of the DaniWeb community
