我知道这是一个老问题，但我想发布一个新答案，使用“事件日历PRO”v3.11和“事件日历：WooCommerce Tickets”v3.11插件，从2015年8月起生效
此代码基于user1664798的答案，修改后执行以下操作：

*/
function conditional_product_in_cart( $product_id ) {
//Check to see if user has product in cart

}
}

$check_in_cart = conditional_product_in_cart(1769);
// Product id 1769 is in cart so show custom fields
if ($check_in_cart === true ) {
// Display custom fields for 1769...

}
}
- 更改了错误的命名方式w/新插件版本
- 显示每个产品的每张票的与会者字段（因此，如果用户购买了事件“A”的2张票和事件“B”的3张票，他们将看到5个字段-前2个字段将标记为事件“A”，最后3个字段将标记为事件“B”）
- 向WooCommerce电子邮件中添加与会者
- 将与会者添加到签出确认页面
- 将与会者添加到“活动日历：WooCommerce票证”插件电子邮件
