WooCommerce预订-检索购物车中的特定数据 - WooCommerce Booking - Retrieving specific data in Cart?

我有这个数组，它是从WooCommerce使用这些行转储的:

$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) { 
    // some code here…
}

如果我对购物车($items)进行原始输出，我会得到以下内容:

array(1) {
  ["f584d8671586d336d84e8cf9ed43303c"]=>
  array(11) {

  }
}

我想使用特定的数据值在php变量(预订日期，时间和人):

  ["date"]=> string(13) "28 août 2016"
  ["_persons"]=> array(1) { [0]=> int(1) }
  ["time"]=> string(11) "21 h 30 min"

我怎样才能从WooCommerce购物车对象中获得这个特定的值?

谢谢

你可以先尝试这个(但我不确定，因为我认为它可以是一个对象，所以可能是它不会工作):

 echo $items[0]['booking']['date'] . '<br>';
 echo $items[0]['booking']['_persons'] . '<br>';
 echo $items[0]['booking']['time'] . '<br>';

如果不使用foreach循环，它将:

$items = WC()->cart->get_cart();
foreach($items as $item) { 
    $date = $item['booking']['date'];
    $person = $item['booking']['_persons'];
    $time = $item['booking']['time'];
}
// displaying values for test
echo 'Booking - Date: ' . $date . '/ Person: ' . $person . '/ Time: ' . $time;
