受 Woocommerce 中將自定義元數據作為帶有標題的 html 樣式表添加到電子郵件中的啟發，我使用以下代碼來顯示與會者信息：add_action('woocommerce_email_order_details', 'action_after_email_order_details', 25, 4 );function action_after_email_order_details( $order, $sent_to_admin, $plain_text, $email ){? ?$event = get_post_meta( $order->get_id(), 'WooCommerceEventsOrderTickets', true );? ?if( ! is_array($event) ) return;? ?$event = isset($event[1][1]) ? $event[1][1] : '';? ?if( sizeof($event) == 0 ) return;? ?$custom = isset($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'] : '',? ?];? ?if( ! $event ) return;? ?// The HTML Structure? ?$html_output = '<h2>' . __('Attendee Info') . '</h2>? ?<div class="discount-info">? ? ? <table cellspacing="0" cellpadding="6"><tbody>';? ?// Loop though the data array to set the fields? ?foreach( $fields_array as $label => $value ):? ?if( ! empty($value) ):? ? ?$html_output .= '<tr>? ? ? ? <th>' . $label . '</th>? ? ? ? <td>' . $value . '</td>? ? </tr>';? ?endif;? ?endforeach;? ?$html_output .= '</tbody></table>? ?</div><br>'; // HTML (end)}但它僅顯示第一個與會者的信息。是否有一個選項可以包含元數據（僅名字和姓氏）但對于woocommerce_email_order_details掛鉤內的所有（多個）與會者？

好吧，我明白了，如果有人需要的話，這是這個函數：
add_action('woocommerce_email_order_details', 'action_after_email_order_details', 25, 4 );
function action_after_email_order_details( $order, $sent_to_admin, $plain_text, $email ) {
$events = get_post_meta( $order->get_id(), 'WooCommerceEventsOrderTickets', true );
if( ! is_array($events) ) return;
$events = isset($events[1]) ? $events[1] : '';
if( ! $events ) return;
// The HTML Structure
$html_output = '<h2>' . __('Attendee Info') . '</h2>
<div class="attendees-info">
<table cellspacing="0" cellpadding="6"><tbody>';
$i = 1;
foreach( $events as $event ) :
if( sizeof($event) == 0 ) return;
// get only first and last name for each attendee
$attendeeFirstName = isset($event['WooCommerceEventsAttendeeName']) ? $event['WooCommerceEventsAttendeeName'] : '';
$attendeeLastName = isset($event['WooCommerceEventsAttendeeLastName']) ? $event['WooCommerceEventsAttendeeLastName'] : '';
$html_output .= '<tr>
<th>Attendee '. $i . '</th>
<td>' . $attendeeFirstName .' '.$attendeeLastName. '</td>
</tr>';
$i++;
endforeach;
$html_output .= '</tbody></table>
</div><br>'; // HTML (end)
// The CSS styling
$styles = '<style>
.attendees-info table{width: 100%; font-family: \'Helvetica Neue\', Helvetica, Roboto, Arial, sans-serif;
color: #737373; border: 1px solid #e4e4e4; margin-bottom:8px;}
.attendees-info table th, table.tracking-info td{text-align: left; border-top-width: 4px;
color: #737373; border: 1px solid #e4e4e4; padding: 12px; width:58%;}
.attendees-info table td{text-align: left; border-top-width: 4px; color: #737373; border: 1px solid #e4e4e4; padding: 12px;}
</style>';
// The Output CSS + HTML
echo $styles . $html_output;
}
