Getting varibale into flash cross-server using FlashVars/Query string

programming flash
1

Ok I have a problem, in that my flash wont do what I want it to.

I would like to host a swf file on my server, and have my users able to embed it in their web pages (on their own servers). I would like a variable to be passed through to the flash file from the embed code. At the moment I have tried both query string and FlashVars and neither seems to be working.

This is the embed code that I am using at the moment:

<object 
    classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
    codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" 
    width="680" height="225">
    <param name="movie" value="http://urlwithheld.com/flashbanners/680x225_coverflow.swf" />
    <param name="FlashVars" value="trackingCode=http://ww2.urlwithheld.com/track/877338/dvd" />
    <param name="allowfullscreen" value="false" />
    <param name="allowScriptAccess" value="always" />
    <param name="quality" value="high" />
    <param name="menu" value="false" />
    <!--[if !IE]> <-->
    <object 
        data="http://urlwithheld.com/flashbanners/680x225_coverflow.swf" 
        width="680" 
        height="225" 
        type="application/x-shockwave-flash">
        <param name="FlashVars" value="trackingCode=http://ww2.urlwithheld.com/track/877338/dvd" />
        <param name="allowfullscreen" value="false" />
        <param name="allowScriptAccess" value="always" />
        <param name="quality" value="high" />
        <param name="menu" value="false" />
        <param name="pluginurl" value="http://www.adobe.com/go/getflashplayer" />FAIL (the browser should render some flash content, not this).
    </object>
    <!--> <![endif]-->
</object>

Now this doesn’t work. It does however work when I change the path of the swf to one located on my local machine, then I get the trackingCode variable passed into flash fine. But off a different server no variable at all is being passed to Flash.

Am I going about this the wrong way? I’m attempting to access the variable in actionscript using _level0.trackingCode

Thanks in advance for any help/discussion on this.

You might need to add a crossdomain.xml file to your server if the Flash file needs to work across different domains. Senocular wrote an excellent description here.
