Yes, you can retreive this value with invoice ID or some other value depending on what your paymant gateway returns. In fact every gateway is different from each other. For sure you should have a returning transaction ID. You could use it to retreive, by querying the database, the total amount in the tblinvoices table. Alternatively gateways usually allow you to specify an order ID or use a note field. Since they both return back, you could store invoice ID in one of them so that in your call back you'll simply need to run this kind of query.


SELECT total FROM tblinvoices WHERE id = $_POST["returning_value_with_id_of_invoice"]

Sure. Normal URL:


SELECT value FROM tblconfiguration WHERE setting = 'SystemURL'




SELECT value FROM tblconfiguration WHERE setting = 'SystemSSLURL'


Even if you could get it also with standard PHP in $_SERVER['SERVER_NAME'];
