我正在使用 woo commerce bookings 插件來預訂旅行，但我想根據(jù)動態(tài)人數(shù)在結(jié)帳頁面上單獨獲取每個人的類型名稱。我發(fā)現(xiàn)堆棧溢出的帖子對我不起作用，它一直說未定義的偏移量 0 作為結(jié)帳頁面上的錯誤。//* Add a new checkout fieldadd_filter( 'woocommerce_checkout_fields', 'ppp_filter_checkout_fields' );function ppp_filter_checkout_fields($fields){$fields['extra_fields'] = array('participant_details' => array( 'type' => 'participant_details', 'required' => false, 'label' => __( 'Participant Details' ) ),);// Add a "persons" hidden input fieldforeach( WC()->cart->get_cart() as $cart_item ) { $persons = $cart_item['booking']['_persons'][0];}echo '<input type="hidden" name="persons" value="' . $persons .
