How add ccavenue payment details

Hi,

I am new to opencart.  I want to know how to add CCAVENUE payment gate way details in this opencart. 

Please let me know how to add Rupees as currency in this shopping cart.

For the payment gateway, have a look at the existing code for paypal and perhaps the securepay example in contributions.

For the currency, you can add it in your store administration. Menu Admin->Configuration->Localisation->Currency. Note that the "value" that you enter is the currency conversion of the price values you enter for all your products to get the equivalent value in any of the currencies you choose to support on the web store.
