Php 行动\商业\新订单\更新ACF

不知道有没有人能帮我，快把我逼疯了！我正试图从一个插件中获取一个日期，该插件将日期按元数据顺序排列，并将值传递给ACF字段。但就是没什么进展

我有另一个用于action_woocommerce_new_order的函数，它从账单详细信息中获取城市信息，如：$order_shipping_city=$order_data['shipping']['city']；当传递到update_字段时，它可以完美地工作

我遇到的问题是$order->get_meta（'Delivery Date'，true）

如果有人能提供帮助，我们将不胜感激。

您能否就您在

$order->get_meta（'Delivery Date'，true）方面遇到的问题添加更多上下文。。。什么不起作用？你发布的数组是什么？是的，当然，好的，那么值应该来自$meta\u value\u date=$order->get\u meta（'Delivery date'，true）；应该是“2020年11月30日”，它的变量$meta_value_date中似乎没有存储，可能我超出了范围，数组是我从订单查询的订单meta_数据对象的一部分。
function action_woocommerce_new_order( $order_id ) { 

    $order = wc_get_order( $order_id );

    $order_data = $order->get_data();

    // get order item metadata (in an unprotected array) 

    $item_meta_data = $order->get_meta_data();

    // Get the specific meta data from a meta_key: 

    $meta_value_date = $order->get_meta( 'Delivery Date', true );
     
    // Update collected date field

    update_field('field_5fae8fb8569c6',$meta_value_date, $order_id);      
  
}; 

// add the action 
add_action( 'woocommerce_new_order', 'action_woocommerce_new_order', 10, 1 );

I am accessing the value like so: $meta_value_date = $order->get_meta( 'Delivery Date', true ); which outputs  30 November, 2020
