Question

I’m trying to fetch some data from php to flash and print it in a dynamic text field. I know this might be a silly question but i cant seem to work out how to get flash to process the code text_field.text = data.return_msg; without it needing an event listener.

So i want the code to be processed as soon as flash discovers it basically.

this is what i have at the moment:

var variables:URLVariables = new URLVariables("get_blog_info.php");


// Build the varLoader variable
var varLoader:URLLoader = new URLLoader;
varLoader.dataFormat = URLLoaderDataFormat.VARIABLES;


trace(varLoader);


var data:URLVariables = new URLVariables(event.target.data);
title_txt.text = data.return_msg;
}

and i get this error:

“1120: Access of undefined property event.”

I know its a basic question, but i’m new to flash so any help would be much appreciated.

Thanks

You need to actually listen to your loader in order to detect when it receives a response from PHP. Only then will you have an event object, and a populated data property. You should be doing something like this:

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE,onLoaded);
loader.load(new URLRequest("get_blog_info.php"));

function onLoaded(evt:Event):void
{
    loader.removeEventListener(Event.COMPLETE,onLoaded); // recomended, to prevent memory leaks. if you will not be using this loader again.
    title_txt.text = evt.target.data;
}

I’ve deliberately ignored your use of URLVariables as I believe you have misunderstood its purpose. You would create an instance of URLVariables with a string of name/value pairs, which are variables that will get sent to your PHP script. Since you don’t seem to be using any variables for the request I have ignored it
