从所有 WooCommerce 预订中获取所有人的总和

我使用官方 woocommerce 预订插件，并尝试获取所有已预订产品的人员的数量。

对于单个订单，没有问题：

if ( is_callable( 'WC_booking_Data_Store::get_booking_ids_from_order_id') ) {
        $booking_data = new WC_booking_Data_Store();
        $booking_ids = $booking_data->get_booking_ids_from_order_id( $order->get_id() );
    }
            foreach ( $booking_ids as $booking_id ) {
            $booking = new WC_booking( $booking_id );
            
            $person_count = array_sum( $booking->get_person_counts() );
            $total_person_count .= 'Booking id: ' . $booking_id . ' Person Count: ' . $person_count . ' ';
        }

但我怎样才能收集所有预订的总和呢？希望你能帮我

要获取所有“完整”预订人数，请使用以下命令：

// get all bookings Ids with a status "complete"
$bookings_ids = get_posts( array(
    'posts_per_page' => -1,
    'post_type'      => 'wc_booking', // booking post type
    'post_status'    => 'complete',
    'fields'         => 'ids',
));

$persons_count = 0; // Initializing
$persons_html  = '<table><tr><th>Booking id</th><th>Persons count</th></tr>'; // Initializing

// Loop through booking Ids
foreach ( $bookings_ids as $booking_id ) {
    $booking = new WC_Booking( $booking_id ); // Get the WC_Booking instance object
    $count   = array_sum( $booking->get_person_counts() );

    $persons_count += $count;
    $persons_html  .= '<tr><td>' . $booking_id . '</td><td>' . $count . '</td></tr>';
}
$persons_html .= '<tr><th><strong>Total count</th><td style="color:red">' . $persons_count . '</td></tr>';

// Output
echo $persons_html . '</table>';

经过测试并有效。

为了让它更轻，你可以替换：

    $booking = new WC_Booking( $booking_id ); // Get the WC_Booking instance object
    $count   = array_sum( $booking->get_person_counts() );

简单地通过：

    $count   = array_sum( get_post_meta($booking_id, '_booking_persons', true) );
