The concept of moving the user to one success page versus another is very similar to the other things we have discussed here. To start with you will need to have a recordset on the page that will select this info from your db. Once the recordset is on the page and confirmed to be working then you can add in the logic that will redirect the user based on this columns value. The code will look like this:
if($row_RSship_country['OrderShipCountryID'] == 'Deutschland'){
header("Location: checkout_success.php");
} else {
header("Location: checkout_success2.php");
}
The if statement is checking the column from your recordset to see if it set to Germany, if it is then the user will be redirected to the checkout success page. If it is not then the user will be sent to the alternate checkout success page.
This code is just for the redirecting, if the code is placed just like this on your confirm page the user will not see this page and be sent directly to one of the checkout success pages. The ideal place for this code would be in place of a redirect that occurs after a server behavior. If you have trouble getting the code implemented correctly please post back with a copy of your confirm page so I can take a look and help you get it in there.
