Invoice null when using PayPal IPN

[sheerlock]

I have recently added the PayPal IPN with near total success.

 

One glitch is that the invoice number is either not sent tp PayPal or not returned correctly by PayPal. Every invoice is "0" ie null. Below is the e-mail debug

 

I have read the instructions regarding PayPal IPN but i cannot figure out why the invoice number can't get through to PayPal.

 

Thanks for any help on this matter.

Might be due to some configuration issues.

 

paste the configuration details as can be seen thru admin.

The invoice number is based on the session variable for the paypal cart id:

$parameters['invoice'] = substr($cart_PayPal_IPN_ID, strpos($cart_PayPal_IPN_ID, '-')+1);

and this is created by

$_SESSION['cart_PayPal_IPN_ID'] = $cartID . '-' . $insert_id;

$_SESSION is in use since PHP version 4.1.0 ... is there a chance that your PHP is older? in which case you could replace it by

$cart_PayPal_IPN_ID = $cartID . '-' . $insert_id;

Thank you for the quick reply.

 

I am running php 4.4.4 Just to see, i tried modifying the code as above but nothing changes.

 

After selecting PayPal payment ( checkout_shipping.php ) and clicking on continue button ( checkout_confirmation.php ) the database returns an error saying that the order number already exists ( order number "0"), i presume that there must be something at that point that generates the order number and for some reason it's not generated in the same way as if "cheque" or "bank transfer" is selected.

 

Thanks

In payment configuraton there is an for individual/aggregate that should be the reason.

 

So hide some important values and paste configuration details.

I'm surprised that the aggregate/individual option causes the problem.

 

I will nevertheless try when our broadband comes back since severe frost hit the country on monday and cut us out of electricity and telephone :lol:

I'm surprised that the aggregate/individual option causes the problem.

 

The "aggregate/individual" has no influence on the invoice number being null.

I added

 

$cart_PayPal_IPN_ID = $cartID . '-' . $insert_id;

 

under where it set the session attribute:

 

$_SESSION['cart_PayPal_IPN_ID'] = $cartID . '-' . $insert_id;

 

in paypal_ipn.php

 

and it seems to have fixed the problem with the "invoice" not being submitted to paypal.
