Hi,

you have to develope a admin panel for your cart,

you can use payment gatway http://www.ccavenue.com/

for that you have to register with them, they provide you a registration id and some code to put in your cart. (This is used to connect to the gatway site and to pass some required field values to gatway.)

see http://www.sari-saree.com, which i hace developed.

thanks for your reply. so now my part of code is add cart,remove product,ext
when i press checkout all the process is handled by payment gateway. and once the payment is sucessfull customer will get sucessful page.
for showing the sucessfull page payment gatway redirect to my site? and when i connect to payment gateway the layout of the page changes?
