For sending additional information,you need to set some custom input names with values after payment. Look at the additional information section in the above code. IN this section, you can see labels Merchant Param1, Merchant Param2 and so on. You can change the names of label but names of input should be  merchant_param1, merchant_param2 etc. You can't change them with custom names like say home_address, office email etc. If you change them CCAvenue process will not send them to the function after successful transaction.
