我需要你在WordPress和woocommerce上的出色技能，我有一个问题，我不知道为什么woocommerce预订抛出这个：
**Fatal error: Call to a member function `has_persons()` on a non-object in `xxx/plugins/woocommerce-bookings/includes/class-wc-booking.php` on line 557**
并停止所有脚本执行。

我使用此修复解决了完全相同的错误消息：
在文件夹中 的/ var / www / html等/可湿性粉剂内容/插件/ woocommerce-预订/包括
在档案中： 类-WC-booking.php
替换：
/**
* Returns if persons are enabled/needed for the booking product
* @return boolean
*/
public function has_persons() {
return $this->get_product()->has_persons();
}
通过：
/**
* Returns if persons are enabled/needed for the booking product
* @return boolean
*/
public function has_persons() {
if ($this->get_product()) {
return $this->get_product()->has_persons();
} else
{
return 0;
}
}
