Hello,
When Paypal runs my IPN script I save all transaction details in a table in a database.
The payment_status can be pending (if echeck and so on) or completed. I store the payment_status in the the table among with all other transaction details. Each transaction has an uniqe txn_id, I do also save the txn_id in the table.
When I payment arrives as completed I first want to check if it is a new payment that has arrived with a new txn_id or if it is an old pending payment with transaction details and a txn_id that is already in the table that has been cleared and completed.
It could also be an txn_id (transaction) that my script already has created an account for so if the payment_status in my table is "completed" for that txn_id I want it to do something else (send me an email or log it).
I don't know how advanced that it but I'm stuck and I can't figure out how to do that so please, I need some help : (
Here is what I did come up with:
$result = mysql_query("SELECT txn_id FROM paypal_sales");
But then I don't know how to find if that txn_id has been used or if the payment_status is completed or pending.
Best Regards
