 * I’m new to php. Is it possible to add code within the description textbox in 
   the cheque gateway? I tried but the code becomes visible in the checkout page(
   except <?PHP which is not visible).
 * Background: I am using the cheque gateway for a cash-before-delivery option. 
   The service provider for this option only operates in certain cities. They have
   provided me with a CSV file of Post Codes they can service. I need to check if
   the customer, when choosing this payment option, has provided a valid post code.
   One option I thought of would be a text input field within the payment gateway
   option where the customer can enter the post code and a button next to it “check
   if available”. Once the customer clicks, it checks the CSV if the pin code is
   serviceable and displays a dialog box with success or failure message.
