Problem with Paypal IPN and Multi-stores contrib

dealwititp · March 23, 2008

Hi all,

I have three online stores configured with the multi-stores contribution. The stores all use the same database. I have also installed paypal ipn v2.3.3 on each store. I ran some live tests with a dummy user account, and in store 1 the paypal ipn works, however the order number does not show up on the checkout_success page.

The same is true for orders in stores 2 and 3, in addition the orders are not displaying in the order history section. When I log into store 1, under the same username, I can see my transactions from stores 2 and 3 in the order history section.

I receive order confirmation emails okay, the download link is displayed (using the download controller module), but the order info is being transmitted to the wrong store. This only happens with paypal ipn.

I thought this might be a multi-store problem, but I also have paypal express checkout installed on each store and it works perfectly.

Any ideas as to why this is happening?

Thanks,

Walt

were the IPN code for apypal modified to suit the multi store functionality.

In IPN.php file there is some code that will update data base or delete table rows.

Unless it is clear which IPN version is being used(paypal_standard definitely needs modification).

Do provide further details.

I didn't update the ipn.php file. Can you tell me what needs to be changed there? I am using the latest PayPal IPN v2.3.3 mod by AlexStudio.

As I stated before Paypal Express Checkout works fine for all three stores. The order number displays and the transaction can be found in the order history page. My plan is to use Paypal IPN for credit card payments and Paypal Express Checkout for persons with verified Paypal accounts.

Thanks for your help,

Walt
