Here's my problem
<script type="text/javascript"><!--
$('#button-confirm').bind('click', function() {
    $.ajax({ 
        type: 'GET',
        url: 'index.php?route=payment/bitcoinpayflow/confirm',
        success: function(url) {
             location = '<?php echo $continue;?>';
        }       
    });
});
//--></script> 
The url returns this:
https://bitcoinpayflow.com/ordersArray // note the lack of space between orders and array. Is this a problem? If it is, I can get it to display in JSON notation with some fiddling.
(
    [order] => Array
        (
        [bitcoin_address] => 1DJ9qiga2fe94FZPQZja75ywkdgNbTvGsW
    )
)
Now, what I want to do is append the entry bitcoin_address to $continue '<?php echo $continue;?>'. which stands for: /index.php?route=checkout/success. so it would read /index.php?route=checkout/success&btc=1DJ9qiga2fe94FZPQZja75ywkdgNbTvGsW. it seems like it should be simple but I can't see how to do it.
The next page has a javascript function that parses the bitcoin address from the url and displays it on the page. This all works fine, I just can't get the bitcoin address to actually show!
