Modifying Admin Order Confirmation Email

[DrByte]

Which PayPal module are you using, and why?

PayPal IPN - Website Payments Standard

[DrByte]

If you were to use the more contemporary PayPal Express Checkout module instead of the older Website Payments Standard, you would already be getting the Transaction ID number in your admin emails, since at least v1.3.9a anyway.
The first line of the admin-copy of the email will show it, like this:

TransID: 2G49759770491990A

Order Confirmation from [Store name here]

Or, if you insist on using the less reliable Website Payments Standard module, you'd have to hack in the following to make the same thing happen with it:
Again, this is based on v1.3.9h:

/ipn_main_handler.php
line 352, add the new line as highlighted here:

        $_SESSION['order_number_created'] = $insert_id;
        $GLOBALS[$_SESSION['payment']]->transaction_id = $_POST['txn_id'];

and
/includes/modules/payment/paypal.php
line 596, add the new highlighted line as shown:

    $PDTstatus = ($pdtTXN_is_unique && $PDTstatus);
    if ($PDTstatus == TRUE) $this->transaction_id = $this->pdtData['txn_id'];
    return $PDTstatus;

Well, Im running 1.38, and my ipn_main_handler.php file doesnt even have 352 lines in it, let alone the line..

$_SESSION['order_number_created'] = $insert_id;

[DrByte]

Notwithstanding that I firmly believe you should be upgrading ASAP, try putting that line after this one instead:

    $order->create_add_products($insert_id, 2);

Perfect, thanks for your help
