but i am still stuck with admin area please guide
Much thanks

I’m not sure your going to see anything extra in the backend with this. This is strictly front end fields. The First & Last name are already part of Woocommerce and WP in general. They just don’t offer that in the registration process. Users have to fill on all that later.

The user’s name however will be added automatically to their account which you’ll find under Users. You’ll find the user by First & Last Name and or their Email.

Hope that helps.

We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
