Contact form in flash: AS3 checking if php sent the email *problem*_问答_开发者

Contact form in flash with AS3 to PHP.

My problem is that the function "showdata" in AS3 does not take variables from the PHP code. It can't see the data=success from PHP, so i always get "error" even though the email was successfully sent. Can you help me by suggesting what to change in function "showdata" or anything else functional?

I am testing on a online server

PHP code:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
    <?php
        $subject =$_POST[theme];
        $message=$_POST[msg];
        $mail_from=$_POST[email];
        $header="from: $name <$mail_from>";
        $to ='test@test.gr';
        $sending=mail($to,$subject,$message,$header);       
        if ($sending) 
            {
            echo "answer=success";
            }   
        else
            {
            echo "answer=error";
            }
    ?>
</body>
</html>

AS3 code

sendbtn.addEventListener(MouseEvent.CLICK,trysend);
function trysend(e:MouseEvent):void{
    if (subject.text == "") {
        statustext.text = "give theme";
    } else if (isValidEmail(from.text) != true) {
        statustext.text = "give email.";
    } else if (body.text == "") {
        statustext.text = "write a message";
    } else {
        var variables:URLVariables = new URLVariables();
        variables.theme = subject.text;
        variables.email = from.text;
        variables.msg = body.text;

        var urlRequest:URLRequest = new URLRequest( "mail.php" );
        urlRequest.method = URLRequestMethod.POST;
        urlRequest.data = variables;

        var loader:URLLoader=new URLLoader();
        开发者_如何学Cloader.dataFormat=URLLoaderDataFormat.VARIABLES;
        loader.addEventListener(Event.COMPLETE, showData);
        loader.load(urlRequest);
    }
}

function showData(evt:Event):void {
    var loader:URLLoader=URLLoader(evt.target);
    var resulting:URLVariables = new URLVariables(loader.data);
    if (resulting.answer == "error") {      
        statustext.text = "Success!";
    } else if (resulting.answer == "success"){
        statustext.text = "error...";
        subject.text="";
        from.text="";
        body.text="";
    }
}


//Validation Email
function isValidEmail(email:String):Boolean {
    var emailExpression:RegExp = /^[a-z][\w.-]+@\w[\w.-]+\.[\w.-]*[a-z][a-z]$/i;
    return emailExpression.test(email);
}

loader.data must contain the string echoed by your PHP code. You have to put it in a URLVariables in order to have it parsed.

function showData(evt:Event):void {
    var result:URLVariables = new URLVariables(loader.data);
    if (result.data == "success") {
    ...

And by the way, set your loader as a member variable and don't write function inside functions ;)

it works now like this:

PHP (dont put it in 'html' 'head' 'body' tags. Create a file only with this code: )

<?php
    $subject =$_POST[theme];
    $message=$_POST[msg];
    $mail_from=$_POST[email];
    $header="from: $name <$mail_from>";
    $to ='test@test.gr';
    $sending=mail($to,$subject,$message,$header);
    if ($sending){      
    print 'response=success';}
?>

ActionScript3:

    function trysend(e:MouseEvent):void{
    Theme = subject.text;
    Email = from.text;
    Message = body.text;

    if (Theme == "") {
        statustext.text = "give a theme";
    } else if (Email == "") != true) {
        statustext.text = "give an email.";
    } else if (Message == "") {
        statustext.text = "give a message";
    } else {

        var variables:URLVariables = new URLVariables();
        variables.theme = Theme;
        variables.email = Email;
        variables.msg = Message;

        var urlRequest:URLRequest = new URLRequest("mail.php");
        urlRequest.method  = URLRequestMethod.POST;
        urlRequest.data = variables;

        var loader:URLLoader = new URLLoader();
        loader.load(urlRequest);
        loader.addEventListener(Event.COMPLETE, showData);
    }
}


    function showData(evt:Event):void {
        var Result:URLVariables = new URLVariables(evt.target.data);
        if (Result.response == "success") {
            statustext.text = "Success!";
            subject.text="";
            from.text="";
            body.text="";
        } else {
            statustext.text = "error";
        }
    }
