我正在使用WooCommerce API开发一个小型Web应用程序。此应用程序需要从wordpress / woocommerce获取信息。
我能够很好地提取这些信息，但是遇到其他问题（这完全是另一个问题。）
woocommerce REST api中的数据作为多维数组返回。
这是单个订单的示例：
array (size=2)

array (size=30)

带有哈希的任何地方我出于安全原因删除了数据。
所以我需要遍历所有订单的输出特定信息。我可以轻松访问主要订单中的字符串＆＃39;使用这个循环的数组：
$orders = $connect->orders->get(22);
foreach( $orders as $order ) {
foreach( $order as $value ) {
echo $value["order_number"];
$value["total"];
}
}
此循环仅在几秒钟内运行并输出数据。
然而，当我从＆＃39; line_items＆＃39;输出数据时主顺序数组中的数组：
1）我似乎无法在没有指定订单ID的情况下这样做，否则我会得到一个未定义的索引：订单和为行项目foreach循环提供的无效参数。
要克服这一点，我已将此行添加到主循环中，以便从“line_items”中获取数据。阵列：
$line_items = $connect->orders->get($value["order_number"]);
$line_items = $orders['order']['line_items'];
然后我运行一个foreach来输出＆＃39; line_items数组中的值＆＃39;
foreach($line_items as $item) {
echo $item['name'];
echo $item['quantity']';
}
这样可行，但输出了＆＃39; line_items＆＃39;这种方式使页面加载速度极慢。循环完成6个订单大约需要40秒。
如果没有这一行：
$line_items = $connect->orders->get($value["order_number"]);
页面渲染时间约为5秒。
我的问题是：这是访问＆＃39; line_items＆＃39;的最佳方法。阵列？
以下是输出订单信息的完整代码，包括订单项。
$orders = $connect->orders->get(22);
foreach( $orders as $order ) {
foreach( $order as $value ) {
echo $value["order_number"];
$value["total"];
//get line items based on current order id - this is the slow bit!
$line_items = $connect->orders->get($value["order_number"]);
$line_items = $orders['order']['line_items'];
//loop through line items
foreach($line_items as $item) {
echo $item['name'];
echo $item['quantity']';
}
}
}
答案 0 :(得分：0)
问题是您的顶级数组有两个元素http和order，而http部分中没有order_number。
所以基本上你正在做
echo $array['order']['order_number']; // works
echo $array['http']['order_number']; // doesn't work.
你可能想要一个SINGLE循环：
foreach($orders['order'] as $order)
echo $order['order_number'];
}
