php with paypal

[ded]

I know how to send paypal the item information, pricing, quantity, etc etc etc.  How do I send paypal a session ID that they will return to me once the payment has been processed?

This works ok if the buyer presses the "Return to Merchant" button.  Is there something that does an auto return?  I need to be able to update the database to show payment confirmed.

 

Actually, even if you click the button, the url reads http://www.Website.com/ordercomplete.php?merchant_return_link=Return+to+Merchant

OK, added the following and brings over the correct URL, But still buyer must click button instead of automatically loading the webpage.

 

              <input type="hidden" name="rm" value="2">

Updating your database is not recommend on your return page.  There is no guarantee the user will return to the return page (even with auto-return enabled).  You should use IPN https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_admin_IPNIntro instead, which is always guaranteed to take place.  It's server to server communication, though, so it's a little bit tougher to setup.  I created a solution that a lot of people are using.  It's posted on PayPal's developer forum:  https://www.x.com/thread/30664
