Thanks so much, I just got some traction on this like 5 minutes ago, I think I’ll finally get this fixed up. Really appreciate your time!

At risk of sounding silly, where does this bit if code go? Info is still not saving to my order. The code I have at the end of my functions.php file is:

add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields6' );

// Our hooked in function - $fields is passed via the filter!
function custom_override_checkout_fields6( $fields6 ) {
     $fields6['billing6']['billing_infos6'] = array(
        'type'      => 'textarea',
        'label'     => __('Alternate Contact Info', 'woocommerce'),
    'placeholder'   => _x('', 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );
     return $fields6;
}

/**
 * Update the order meta with field value
 */
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['billing6'] ) ) {
        update_post_meta( $order_id, 'Alternate Contact Info', sanitize_text_field( $_POST['billing6'] ) );
    }
}

Thanks so much for your time!
