Question

.send v .sendAndLoad

Hi all,

I have a simple sendForm(); function that compiles vars, builds a form in AS2 and sends the form to a CGI script on the host ISP for email delivery. I use the LoadVars object to collect and send the vars to the CGI script. The final part of the function sends the data to a URL and targets a blank window for a return message and uses the POST method. All works fine when the form is submitted using a simple button and the .send method of the LoadVars class.

However, I want to prevent the default CGI script return page from appearing by preventing the browser opening a new window (or replacing the swf using _self), so I used the .sendAndLoad method and replaced the 'window' target with a gotoAndStop frame, which carries a successful deliver message.

The problem is that the form date is not posted to the URL, but the swf does advance to the gotoAndStop frame, which shows the successful delivery message. Can anyone tell me why the date is not being sent to the URL with the .sendAndLoad method?

Code:

var feedbackForm:LoadVars = new LoadVars();

function sendForm() {
feedbackForm.recipient = "info@somedomain.com";
other form constructs here
feedbackForm.sendAndLoad(" http://formmail.dreamhost.com/cgi-bin/formmail.cgi", gotoAndStop("correct"), "POST");
}

//onRelease
this.contactForm.submitBtn.onRelease = function() {
if ( form validation here) {
gotoAndStop("error");
} else {
sendForm();
}
}

This problem is vexing to say the least and it is not the first time that I have had .sendAndLoad issues. Any help is very much appreciated.

I can't believe that you cannot use the sendAndLoad method to handle/post form data and email with the express aim of preventing the CGI script returning an unwanted web page or other data

-The assumption is that (in alignment with the secuirty measures) you have control over the server scripting and get them to return what you want... or that if someone else exposes their functionality to flash via crossdomain permissions, then its intended to return something that flash can use.

The other option here would be to ask Dreamhost to grant permission for its other subdomains in their (existing) crossdomain.xml file there. Doesn't seem unreasonable...

You might be able to get it to work as is if you publish your swf for player 6 version and you're on the dreamhost.com domain somewhere. I think most of the security changes were designed not to break older flash content....

On checking the docs you could be right about data handling; it seems that pre Flash v7 you could handle/pass data between/within a superdomain but post v7 players cannot handle data outside the exact same domain. If that is true then I cannot handle data through the sendAndLoad method (I am using Player 8+).

So, with that in mind I went back to the onLoad method but I am still getting a post failure, that is, the data is not being sent to the URL.

I'll post the answer here when I get one. I can't believe that you cannot use the sendAndLoad method to handle/post form data and email with the express aim of preventing the CGI script returning an unwanted web page or other data. Especially as the Flash documentation tells you to use .sendAndLoad in preference to .send to prevent the returning html opening in a new window.

Oh well, I guess this is an example of why we don't actually sleep anymore!

Good luck with it. I think there's a difference for permissions where data loading is concerned.
The send method is just like the browser sending and loading. Flash doesn't get access to the response.

For load and sendAndLoad it requires permission. At least that's the way I read the docs. I might be wrong.

Good points.

The swf is hosted at dreamhost but obviously not in their email web server, but nevertheless it is in their server system. The form was processed correctly through the .send method so I can't see a cross-domain issue affecting the .sendAndLoad method usage and not the .send method.

I'll check the handling with Fiddler2 and see what that throws up.

Thanks for some really great help!

submitFeedbackResponse.onData only fires and sends it to the 'error' frame if there's an error with the data exchange. I believe its a crossdomain issue and that unless your swf is hosted at formmail.dreamhost.com or unless you're somehow proxying that request via a script on the server at your own domain that it won't work.

Are you using windows? If so I would check what's happening with Fiddler2 (HTTP debugger) . This will let you see if its trying to load a policy file first and failing, or if there's some problem with the LoadVars exchange after that.

OK, got that, thanks.

\On testing the script, from the live server, I am getting the 'error' frame and the data is not being sent.

Is this because the submitFeedbackResponse.onData(src) function is firing before the sendForm() function, and causing the src to be undefined as the script has not returned anything?

sorry, I had a typo originally which I corrected.
submitFeedbackResponse.onData=function(src) {

I am on the domain but I do need out of domain access, which I have achieved by forwarding the email from within Dreamhost's web panel (pain in the neck), especially as Comcast has refused to accept redirects/forwards. Sigh.

The code looks good but I am getting a syntax error? Can't see it, but FL suggests the: submitFeedbackResponse.onData(src) { line?

var feedbackForm:LoadVars = new LoadVars();
var submitFeedbackResponse:LoadVars = new LoadVars();

function sendForm() {
feedbackForm.recipient = "info@ssmiles.com";
feedbackForm.realname = contactForm.userName.text;
feedbackForm.email = contactForm.userEmail.text;
feedbackForm.feedback = contactForm.userComments.text;

feedbackForm.sendAndLoad(" http://formmail.dreamhost.com/cgi-bin/formmail.cgi", submitFeedbackResponse, "POST");
}

submitFeedbackResponse.onData(src) {
if (src !=undefined) {
gotoAndStop("correct");
} else {
gotoAndStop("error");
}
}

A quick question: can you access that script? You will need crossdomain permission if you're not on that domain. It seems that therealsuperhero has access.

http://formmail.dreamhost.com/crossdomain.xml

Yes, its a default html web 'thank you' type page that they return.

Do I drop the URL encoded value from the if statement and just look for a return of data?
