Save custom checkout field value as user data on WooCommerce

问题

I've added a custom checkbox in the checkout page of my WooCommerce shop for the optional newsletter subscription:

add_action( 'woocommerce_after_order_notes', 'add_checkout_newsletter_subscribe', 9 );

function add_checkout_newsletter_subscribe() {

    woocommerce_form_field( 'checkout_newsletter', array(
       'type'          => 'checkbox',
       'class'         => array('form-row checkout-newsletter-box'),
       'label_class'   => array('woocommerce-form__label woocommerce-form__label-for-checkbox checkbox'),
       'input_class'   => array('woocommerce-form__input woocommerce-form__input-checkbox input-checkbox'),
       'required'      => false,
       'label'         => 'Subscribe me.',
    )); 

    }

I've created a similar checkbox for the My Account page:

add_action( 'woocommerce_edit_account_form', 'display_checkbox_in_account_page' );
function display_checkbox_in_account_page() {

    woocommerce_form_field( 'newsletter-account', array(
        'type'  => 'checkbox',
        'class' => array('form-row-wide'),
        'label' => __( 'Subscribe me.', 'woocommerce' ),
        'clear' => true,
    ), get_user_meta(get_current_user_id(), 'newsletter-account', true ) );
}

add_action( 'woocommerce_save_account_details', 'save_checkbox_value_to_account_details', 10, 1 );
function save_checkbox_value_to_account_details( $user_id ) {
    $value = isset( $_POST['newsletter-account'] ) ? '1' : '0';
    update_user_meta( $user_id, 'newsletter-account', $value );
}

Now I'm looking for a way to connect the two checkboxes.

What I want to obtain is that if a customer flag the checkbox in the checkout page and it is a registered user, also the checkbox in the "My Account" page should be flagged.

I think I need to use the woocommerce_edit_account_form hook but unfortunately I've not other clues on how to obtain such a result.

Can you guys point me in the right direction?

Thank you very much for your help!

The following will show the subscription checkbox on checkout page, if customer hasn't subscribe yet, and it will save it as user meta data on submission:

// Display custom checkout field on checkout page
add_action( 'woocommerce_after_order_notes', 'add_checkout_newsletter_subscribe', 9 );
function add_checkout_newsletter_subscribe() {

    $user_id    = (int) get_current_user_id();
    $newsletter = get_user_meta( $user_id, 'newsletter-account', true );

    // If newsletter hasn't been subscribed yet we show the subscription checkbox on checkout
    if ( $user_id > 0 && ! $newsletter ) :

    woocommerce_form_field( 'checkout_newsletter', array(
       'type'          => 'checkbox',
       'class'         => array('form-row checkout-newsletter-box'),
       'label_class'   => array('woocommerce-form__label woocommerce-form__label-for-checkbox checkbox'),
       'input_class'   => array('woocommerce-form__input woocommerce-form__input-checkbox input-checkbox'),
       'required'      => false,
       'label'         => __('Subscribe me'),
    )  );

    endif;
}

// Save custom checkout field value as user meta data
add_action('woocommerce_checkout_update_customer','custom_checkout_checkbox_update_customer', 10, 2 );
function custom_checkout_checkbox_update_customer( $customer, $data ){
    if ( ! is_user_logged_in() || is_admin() )
        return;

    // Update user meta data
    if ( isset($_POST['checkout_newsletter']) )
        update_user_meta( $customer->get_id(), 'newsletter-account', '1' );
}

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

It works with your question code for my account page:

add_action( 'woocommerce_edit_account_form', 'display_checkbox_in_account_page' );
function display_checkbox_in_account_page() {

    woocommerce_form_field( 'newsletter-account', array(
        'type'  => 'checkbox',
        'class' => array('form-row-wide'),
        'label' => __( 'Subscribe me.', 'woocommerce' ),
        'clear' => true,
    ), get_user_meta(get_current_user_id(), 'newsletter-account', true ) );
}

add_action( 'woocommerce_save_account_details', 'save_checkbox_value_to_account_details', 10, 1 );
function save_checkbox_value_to_account_details( $user_id ) {
    $value = isset( $_POST['newsletter-account'] ) ? '1' : '0';
    update_user_meta( $user_id, 'newsletter-account', $value );
}

If the checkout option has been ticked when placing an order, the checkbox on edit account form will be checked too…
