I wanted to pass the invoice number so it will show on the Paypal email notice to the customer.<br /> In post-functions.php look for this line in the Paypal section:<br /> $paypal_params['custom'] = $form_id.'_'.$entry_id.'_'.$entry_timestamp;</p> <p>And then you can add this line:<br /> $paypal_params['invoice'] = $form_id.'_'.$entry_id;</p> <p>Paypal's dashboard and email will then show the invoice number. </p> https://www.machform.com/forums/topic/invoice-number-not-passing-to-paypal#post-20541 Thu, 27 Mar 2014 16:24:50 +0000 yuniar 20541@https://www.machform.com/forums/ <p>The invoice number is not being passed indeed, since v3.5 already support IPN and you should be able to track the payment status and get the Transaction ID directly from your MachForm panel. </p> https://www.machform.com/forums/topic/invoice-number-not-passing-to-paypal#post-20516 Mon, 24 Mar 2014 23:26:31 +0000 fdjordan 20516@https://www.machform.com/forums/ <p>After updating to 3.5, the invoice number is no longer passing to paypal.<br /> Has anyone else had this issue, is there a variable I need to update?</p> <p>Thanks </p>
