I found an issue with the Blockchain.info PHP examples

[PBmining]

Hello everybody.  I would like to make a contribution back to you guys for helping me learn how to accept BTC payments with PHP.
Anyone who uses the PHP examples provided by Blockchain.info will realize that the callback is not returning an invoice number.   This can cause a lot of confusion, especially for those just starting out.

After looking at Index.PHP for awhile, I found the culprit!

<div class="blockchain-btn" style="width:auto" data-create-url="create.php">  

To pass the invoice # along, you need to add this:

<div class="blockchain-btn" style="width:auto" data-create-url="create.php?invoice_id=<?php echo $invoice_id;?>">

They only tacked that variable onto the order status URL, but its create.php that needs it...

another issue is that the examples use your original btc address to generate the QR code, which will cause the callback not to fire back.

$my_bitcoin_address was set in the include as the btc address to forward to.


<img style="margin:5px" id="qrsend" src="<?=$blockchain_root?>qr?data=bitcoin:<?=$my_bitcoin_address?>%3Famount=<?=$price_in_btc?>%26label=Pay-Demo&size=125" alt=""/>

I believe that the most apropriate thing you could do would be to contact them if you haven't already.

I believe that the most apropriate thing you could do would be to contact them if you haven't already.

This is an old thread, but I did contact them many times about that.  I felt that giving everyone the heads up was the appropriate thing to do as well.  I thought it might help someone out there.
