Flash/PHP

Hey,

I'm trying to create a flash based survey and I'm having some problems. Here is what I've got...

I've got a bunch of variables coming into Flash from a php script...survey questions and corresponding choices. A question could have up to 10 possible choices. I want to set up the file so that if a question only has, say 3 answers, only 3 buttons are visible on the stage. I can't seem to get that part to work. Also, once a user clicks on an option, how do I send what they clicked on BACK to php.

Thanks for helping.

Hi, not to sure about the checking bit, you could try something like:

if(question2Answer == null || question2Answer == "")
{
button2._y = -500;
}

Thats only really for the checking part. Hide the button as you please, chaning its _y was just a suggestion. null might have a capital n, Null or NULL...cant remember off the top of my head. different things, different languages etc.

As for posting the variables back to php take a look at LoadVars. Theres quite alot of material about on how to use it.

in actionscript (1.0) its "undefined" u should be checking against

sending back to the server
var x = new LoadVars();
x.myvar1 = 11;
x.myvar2 = "hello";
x.Send("addressofphp","post");

ur php as normal

$incoming1 = intval($_POST['myvar1']);
$incoming2 = $_POST['myvar2'];
