variable as POST key with URLVariables in AS3?

[thesmithman]

Hello,
I have an array of data objects that I would like to send from my .swf to a server-side script. I would like to loop through the array and assign a variable key name to each name-value pair, for example:

myVars = new URLVariables;
for(i in objectArray){
var keyName = 'obj_' + i;
myVars.keyName = objectArray[i].data;
}

But when I try to use this method, the parser treats 'keyName' as a string.

Is it possible to do this? or do I have to write a very long switch/case statement?

Your insight is appreciated!
many thanks,
thesmithman

Hi thesmithman,

So, have you found the solution?
(I know it's an old thread, hehe.. But I ended up here from google.)

I didn't find the solution within flash itself, but here is what I did to get it works.

Instead of setting URLVariables object property, I use its constructor. Since the constructor can only hold one name/value pair, I make a single tricky name/value pair (v) containing all variables.

var fvParameters:Object = LoaderInfo(this.loaderInfo).parameters;
var key:String;
var val:String;
var flashVars:String = "v=";

for (key in fvParameters) {
	flashVars += key + ":" + String(fvParameters[key]) + ";";
}

// length-1 to remove last ; character
urlVariables = new URLVariables(substr.(0, (flashVars.length - 1)));

On server side I can extract the 'v' variable content, using php:

$v = split(';', $_GET['v']);
while (list($key, $val) = each($v)) {
    $tmp = split(":", $val);
    $vars[$tmp[0]] = $tmp[1];
}

Regards,
Ihsan.
