How to make a .swf object link to paypal the same way as paypal buttons do?

Paypal buttons use forms, ie:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" va开发者_运维问答lue="_s-xclick">
<input type="hidden" name="hosted_button_id" value="xxxxxxxx">
<input type="image" src="img.jpg" border="0" name="submit" >
</form>

I'd like buyers to click on a .swf file (instead of an image) which brings them to paypal's checkout, what's the best way to accomplish this?

Thanks
