Re: [Flashcoders] Detecting referrer in Flash
public _url : String [read-only]
Retrieves the URL of the SWF file that created the button.
*Availability: *ActionScript 1.0; Flash Player 6
Example
Create two button instances on the Stage called one_btn and two_btn. Enter
the following ActionScript in Frame 1 of the Timeline:
var one_btn:Button;
var two_btn:Button;this.createTextField(output_txt, 999, 0, 0, 100, 22);
output_txt.autoSize = true;
one_btn.onRelease = function() {
trace(clicked one_btn);
trace(this._url);
};
two_btn.onRelease = function() {
trace(clicked +this._name);
var url_array:Array = this._url.split(/);
var my_str:String = String(url_array.pop());
output_txt.text = unescape(my_str);
};

Is there any way to determine which web page is displaying my SWF? This

using this to determine how to match the theme of the source page, not
for security.

Re: [Flashcoders] Detecting referrer in Flash
The referrer is not the page displaying your SWF. The referrer is the page you linked FROM to get to the page displayign your SWF. If I come from a link in my blog to your site, my blog is the referrer. You can't get the referrer from Flash, so you must use ExternalInterface and use JavaScript to pass it back to Flash. However, it sounds like you want the page displaying your SWF, which is easy. It's the _url property. I think this._url in the main timeline is sufficient but you can check the help system.

RE: [Flashcoders] Detecting referrer in Flash
If you'd rather have something more secure, then I'd suggest calling a backend to pass it to you. This gets a lot more complicated as you'd now have to tack on session management. The other option is to use JavaScript/AJAX to pull data from a request or response. Are you putting your SWF on an HTML page or a JSP/ASP/PHP page? If it's the former, there really is no other way outside of using session management + XML/JavaScript/AJX. If it's the latter, then you can have the JSP/ASP/PHP page write the referrer to the FlashVars. However, if you get referrer URL's with querystrings attached, you could potentially run into issues there as well as you'd have to parse through the referrer's querystring. I'm not sure if there's an easy answer for this outside of having Flash do a separate call to get the referrer URL once the SWF has loaded. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Mudge Sent: Thursday, May 03, 2007 9:00 PM To: flashcoders@chattyfig.figleaf.com Subject: RE: [Flashcoders] Detecting referrer in Flash You can use FlashVars to pass it into your SWF via the HTML embed. I'm currently using an anchor (foo.swf#abc) or file parameters (foo.swfitem=abc), which work fine. But can I do any better than this? I feel that passing in a parameter is an invitation for tampering... Not that it's incredibly critical, but it'd be nice if developers could just drop-in the SWF without having to configure it. public _url : String [read-only] This gives the URL of the SWF itself -- this is already known. - Kipp ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
