Platnosci payment gateway integration php

• Create a Account in Platnosci

• Get these details

• PlatnosciId
•  Authorisationkey
•  Platnosci signature Key1
•  Platnosci signature Key2
•  Platnosci gateway URL

• Before the passing the Payment details to payment Gateway we need to store the details of what we are passing such as unique id,amount,product id like that

• After inserting these datas into the database we need to redirect to a html page

Sample html page

<form name="platnosci_payment"  action="https://www.platnosci.pl/paygw/ISO/NewPayment"  method="post">
<input type="hidden" name="first_name" value="firstname" />
<input type="hidden" name="last_name" value="lastname" />
<input type="hidden" name="email" value="email" />
<input type="hidden" name="address" value="address" />
<input type="hidden" name="city" value="city" />
<input type="hidden" name="platno_postcode" value="postcode" />
<input type="hidden" name="platnoTotal_price" value="Total_price" />
<input type="hidden" name="pos_id" value="platno_pos_id" />
<input type="hidden" name="pos_auth_key" value="platno_pos_auth_key" />
<input type="hidden" name="session_id" value="uniqueid" />
<input type="hidden" name="amount" value="Total_price*100" />
<input type="hidden" name="desc" value="description" />
<input type="hidden" name="client_ip" value="ClientIp Address" />
<input type="hidden" name="js" value="1" />
</form>

After the Success full payment we will be returned to the success url

we need to validate the return parameters to check whether the payment was success or failure

checking success/failure payment
