Question

In woocommerce, after creating and registering some custom account fields in a custom php file using the following code:

Answer 1

If you want to include your custom "Shipping phone" field in Backend User profile under "Customer's shipping address" section, you will use the following instead:

add_filter( 'woocommerce_customer_meta_fields', 'filter_add_customer_meta_fields', 10, 1 );
function filter_add_customer_meta_fields( $args ) {
    $args['shipping']['fields']['shipping_phone'] = array(
        'label'       => __( 'Shipping phone', 'woocommerce' ),
        'description' => '',
    );
    return $args;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

This little code snippet will do it all. If you change the value in this "Shipping phone" field, it will be updated without needing any additional code.
