Custom fields in user profile page

We can add custom fields to the user profile page as like the post types.
user_contactmethods filter will do the trick


if (!function_exists('custom_user_contactmethods')) {

    function custom_user_contactmethods($user_contactmethods) {
        return array_merge($user_contactmethods, array(
                    'address1' => __('Address Line1')
                   /*We can add multiple fields in this array.*/                      
                   )

        );
    }

}
add_filter('user_contactmethods', 'custom_user_contactmethods', 5, 1);




Note: The fields added through this filter will get appeared only while editing the user's profile page. It wont be available while creating a user.
