INTEGRATE PRZELEWY PAYMENT GATEWAY
-------------------------------------
1. Create account in Przelewy payment gateway
2. Get p24_id_sprzedawcy
3. Przelewy uses redirect model for payment
ie redirecting to the merchant site for making payment
4. so before proceeding the payment we need to save the buy details such as
uniqueid, quantity, price, product details, etc...
5. After saving these details render a html with the details and make it auto submit or
make the user to submit once more with the details already entered

<?php
$actionUrl = "https://secure.przelewy24.pl/index.php";
$p24_id_sprzedawcy = 58952;//p24_id_sprzedawcy
$prz_postdata = array("lastname" => $paymentdata['lastname'],
"p24_session_id" => $unique_id,// should be unique in every payment
"p24_id_sprzedawcy" => $p24_id_sprzedawcy, //merchant id
"p24_kwota" => $amount,//pass amount as it is 10.30
"p24_comment" => "Deal no:".$dealdetails['DealId']."source:".$dealdetails['test'],
"p24_klient" => $paymentdata['firstname'],// name of user
"p24_adres" => $paymentdata['address'],//address of user

6. After the successfull Completion of Payment Przelewy will return the details of the payment via url
7. we get orderid ,session id and price of the product
8. the next step is to verify is that the confirmed purchase is a manupulated one or not
9. ie any data send to the payment gateway is changed by the user or not
