从as3向php发送变量到电子邮件

Question

I'm working on a flash content on my website that contains an input box and a submit button. The user should put an answer of a question in the input box and when he clicks on submit, the answer should be sent to an email address. The problem is, when a user enters an answer, I receive an empty email message. Here are my codes:

Text box's code:

var myData:URLVariables = new URLVariables();
myData.answer = "";
var myRequest:URLRequest = new URLRequest("MyDomain/..../example.php");
myRequest.data = myData;
myRequest.method = URLRequestMethod.POST;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;

The button's code:

myButton.addEventListener(MouseEvent.CLICK, sen) ;
function sen(Event:MouseEvent):void
{
navigateToURL( new URLRequest("MyDomain/..../example.php"), "_self");
}

and this is the PHP code:

<?php
$answer = $_POST['answer']; 
$to = "MyMail@example.com";
$subject="Message from php";
mail($to,$subject,$text,"Content-Type: text/plain; charset=utf-8");
?>

So what's wrong with it?

Answer 1

You never defined the variable $text in your PHP code. You are probably missing in your code something like this:

$text = $_POST['text'];

or you should use $answer variable instead of the $text variable.

You could write some debug code to see what you have submitted from your AS3 code:

<?php
$text = var_export($_POST, true);
// not used anyway
// $answer = $_POST['answer']; 
$to = "MyMail@example.com";
$subject="Message from php";
mail($to,$subject,$text,"Content-Type: text/plain; charset=utf-8");
?>

This way you would get an email containing all the POST variables, so you can see which one you need to reference in your $_POST[] array.
