Php 将从Woocommerce 3中的外部交付服务接收的数据保存到订单

如何在元数据中保存来自delivery service的订单id

    add_action('woocommerce_thankyou', 'send_order_to_delivery');
    function send_order_to_delivery( $order_id ){
        // Send data
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://app.axample.com/api/index.php?new_order");
        curl_setopt($ch, CURLOPT_FAILONERROR, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        $result = curl_exec($ch);
        curl_close($ch);

        $json = '$result';

        $delivery_order_id = json_decode($json)->order_id;

        if ( ! empty( $_POST['delivery_order_id'] ) ) {
            update_post_meta( $order_id, 'delivery_order_id', sanitize_text_field( $_POST['delivery_order_id'] ) );
        }
    }

当我将订单发送给外部送货服务时，我得到的答案是

echo$result-

{"result":"success","order_id":100888,"order_number":10}

需要保存此新订单的“订单id”：100888

。

请尝试以下操作

add_action('woocommerce_thankyou', 'send_order_to_delivery');
function send_order_to_delivery( $order_id ){
    // Send data
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://app.axample.com/api/index.php?new_order");
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($ch);
    curl_close($ch);

    $decoded = (array) json_decode($result);

    // Test output
    if( isset($decoded['result']) && $decoded['result'] == 'success'  && isset($decoded['order_id']) && !empty($decoded['order_id']) ){
        update_post_meta( $order_id, 'delivery_order_id', esc_attr( $decoded['order_id'] ) );
    } 
}

代码进入活动子主题（或活动主题）的function.php文件。它应该可以工作。

print\r（$result）；show:{“result”：“success”，“order_id”：7294718，“order_number”：7}我意识到需要使用json_decode（）。foreach——错了。不确定是否保存元数据…完美！非常感谢你！
