在WooCommerce电子邮件订单元中获取自定义域数组值

Question

null

我希望能够从数组中获取某些元值，例如WooCommerceEventsAttendeEname、WooCommerceEventsAttendeElastName、FooEvents_Custom_State/Pavinic、FooEvents_Custom_Address、FooEvents_Custom_Title等。

这个PHP代码段将添加一个字段的订单电子邮件，但我如何编辑这一点，我可以让它显示一些元从数组？

 /**
 * Add a custom field (in an order) to the emails
 */
add_filter( 'woocommerce_email_order_meta_fields', 'custom_woocommerce_email_order_meta_fields', 10, 3 );

function custom_woocommerce_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
    $fields['meta_key'] = array(
        'label' => __( 'Label' ),
        'value' => get_post_meta( $order->id, 'meta_key', true ),
    );
    return $fields;
}

对于特定的WooCommerce订单，我使用

echo '<pre>'; print_r( get_post_meta( '4609', 'WooCommerceEventsOrderTickets', true ) ); echo '</pre>';

这表明：

Array
(
    [1] => Array
        (
            [1] => Array
                (
                    [WooCommerceEventsProductID] => 454
                    [WooCommerceEventsOrderID] => 4609
                    [WooCommerceEventsTicketType] => 
                    [WooCommerceEventsStatus] => Unpaid
                    [WooCommerceEventsCustomerID] => 64
                    [WooCommerceEventsAttendeeName] => AttendeeFirst
                    [WooCommerceEventsAttendeeLastName] => AttendeeLast
                    [WooCommerceEventsAttendeeEmail] => [e-mail]
                    [WooCommerceEventsAttendeeTelephone] => 607-123-4567
                    [WooCommerceEventsAttendeeCompany] => 
                    [WooCommerceEventsAttendeeDesignation] => 
                    [WooCommerceEventsVariations] => Array
                        (
                            [attribute_pa_registration-options] => nassgap-member
                        )

                    [WooCommerceEventsVariationID] => 4078
                    [WooCommerceEventsPrice] => $675.00
                    [WooCommerceEventsPurchaserFirstName] => Jon
                    [WooCommerceEventsPurchaserLastName] => Fuller
                    [WooCommerceEventsPurchaserEmail] => [e-mail]
                    [WooCommerceEventsCustomAttendeeFields] => Array
                        (
                            [fooevents_custom_address] => 123 Attendee St
                            [fooevents_custom_city] => Attendee City
                            [fooevents_custom_state/province] => Nevada
                            [fooevents_custom_postal_code] => 13813
                            [fooevents_custom_organization] => Attendee LLC
                            [fooevents_custom_title] => Attendee Title
                        )

                )

        )

尝试下面这样的方法（因为我不能真正测试它，您可能应该安排它）：

add_filter( 'woocommerce_email_order_meta_fields', 'custom_woocommerce_email_order_meta_fields', 10, 3 );
function custom_woocommerce_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
    $event = get_post_meta( $order->get_id(), 'WooCommerceEventsOrderTickets', true );

    if( ! is_array($event) ) return $fields;

    $event = isset($event[1][1]) ? $event[1][1] : '';

    if( sizeof($event) == 0 ) return $fields;

    $custom = isset($event['WooCommerceEventsCustomAttendeeFields']) ? $event['WooCommerceEventsCustomAttendeeFields'] : '';

    // Set our array of needed data
    $fields_array = [
        __('First name')    => isset($event['WooCommerceEventsAttendeeName']) ? $event['WooCommerceEventsAttendeeName'] : '',
        __('Last name')     => isset($event['WooCommerceEventsAttendeeLastName']) ? $event['WooCommerceEventsAttendeeLastName'] : '',
        __('Title')         => isset($custom['fooevents_custom_title']) ? $custom['fooevents_custom_title'] : '',
        __('Organization')  => isset($custom['fooevents_custom_organization']) ? $custom['fooevents_custom_organization'] : '',
        __('Address')       => isset($custom['fooevents_custom_address']) ? $custom['fooevents_custom_address'] : '',
        __('City')          => isset($custom['fooevents_custom_city']) ? $custom['fooevents_custom_city'] : '',
        __('Postcode')      => isset($custom['fooevents_custom_postal_code']) ? $custom['fooevents_custom_postal_code'] : '',
        __('State')         => isset($custom['fooevents_custom_state/province']) ? $custom['fooevents_custom_state/province'] : '',
    ];

    // Loop though the data array to set the fields
    foreach( $fields_array as $label => $value ){
        if( ! empty($value) ){
            $fields[] = array(
                'label' => $label,
                'value' => $value,
            );
        }
    }

    return $fields;
}

代码放在活动子主题（或活动主题）的function.php文件中。应该管用。

您将得到如下内容：
