I used this class in my project:
http://www.saaraan.com/2012/07/paypal-expresscheckout-with-php
I modify some of the codings in process.php.
And 2 json variables passed into the php for the transaction data.
The transaction is successful. But only the total price can be displayed in seller account finally.
It is quite weird.
I have looked into the old posts, that with no luck...
- I have set to use a latest version nvp 106.0
- I have added useraction=commit for the webscr url redirection.
- I have setup items' parameters for both SetExpressCheckOut method and DoExpressCheckOut method.
Any solutions for my case??~
Here are my codings:
