Processing a PHP variable in AS3

[Mike_King]

I have looked in every book that I have on AS3 and cannot come up with a solution to this, I hope that someone can help me.

I am receiveing a data string from a PHP --- mySQL connection on my web server. The string is arriving in flash as I can trace it and see the variables. If I do a trace on event.target.data I see the following.

&numResult1=4&numResult2=14&numResult3=37&numResult4=70&numResult5=5&numResult6=3&doneLoading=true

This is exactly what I should be seeing based on my PHP code.

I am trying to assign the numResult numbers to a dynamic text box, for instance numResult1 = 4, I would like to assign that 4 to a dynamic text field on the Flash Stage. I have not figured out a way to get the variable out of the string.

I keep getting undefined or a variety or other errors with the different methods I try.

I have tried numerous ways using the URLVariables class but I have had no luck. Use to be very simple in AS2, I could assign the variable right to the dynamic text field in the properties panel, not anymore.

Does anyone know how I can do this. People are doing it all the time, it can't be that hard, is it?????

Just a good example as to how to break the variables out would be really helpful. I have tried the FlashGods site and could not figure there examples out, in fact the two I tried did not work at all.

I would appreciate any help.... Thank you.

your urlloader has a data property which has numResult1 and numResult2 etc properties.

you'll probably need to cast your urlloader's data property as a urlvariable.

I have been trying to work this through for over a week, here is the ActionScript Code;



AS

function getData(event:Event):void {
var myURLLoader:URLLoader = new URLLoader();
var myURLRequest:URLRequest = new URLRequest("polls2.php"); // Actually goes to a web site.
myURLLoader.dataFormat=URLLoaderDataFormat.TEXT;
myURLLoader.load(myURLRequest);

myURLLoader.addEventListener(Event.COMPLETE, completeHandler);

function completeHandler(event:Event):void {
trace(myURLLoader.data);
var myURLVariables:URLVariables = new URLVariables(myURLLoader.data);


}
gotoAndStop(2);
}

Here is what I get with the Trace Statement:

&numResult1=6&numResult2=6&numResult3=5&numResult4=9&numResult5=7&numResult6=1&doneLoading=true


Here is what I get when I try to set the URL variables.

Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
at Error$/throwError()
at flash.net::URLVariables/decode()
at flash.net::URLVariables()
at MethodInfo-2()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()


Now it sure looks to me that the string being passed is name/value pairs.

I have tried every way that I can think of to capture this data. I must be missing something simple.

Any ideas would be greatly appreciated.

Thanks for your help.

yes, but you didn't inform your loader that it was receiving variable/value pairs. it thinks it's receiving text (the default dataformat). try:

This was already solved over at flashgods.org.

The URLVariables was not the main issue. You can set the URLLoader's dataFormat to URLLoaderDataFormat.VARIABLES. And I believe you still need to cast the data property as a URLVariables before accessing the values (I didn't try not doing that).
Beyond that, the issue was the urlencoded string having a prepended ampersand.

You can get away with a prepended ampersand in as2 with LoadVars (although I never do that) but apparently in as3 you can't. The urlencoded values need to match what you would see in the browser address bar after the ?, i.e. no initial ampersand.

[Mike_King]

Working through the Live Support at Flash Gods they helped me work through the issue.

The data string included an ampersand at the beginning of the string, once I modified the PHP code to remove that ampersand the data was processed as expected.

This was an interesting one. I am not certain that I would have ever thought about that character causing the issue.

I appreciate all the responses to the post.

Thanks.
