从逗号分隔的订单ID中获取有效的WooCommerce订阅

Posted 2021-04-21

尝试使用wcs_get_subscriptions功能来检索订阅信息以创建可打印标签。

我让插件在查询字符串中传递以逗号分隔的订单ID列表到脚本中，但是我不确定如何将ID字符串传递到函数中：

这是我的实际代码：

$subscriptions = wcs_get_subscriptions( array( 
    'subscriptions_per_page' => -1,
    'subscription_status' => array('active'), 
    'post_id' => array(123,456,789) 
));

foreach($subscriptions as $sub){ 
     echo $sub->get_shipping_city(); 
}

答案

您的代码中有一些错误：

• 参数post_id不存在并且没有效果。
• 您可以使用有效参数order_id，但只能处理一个订单ID。

现在代替使用内置函数wcs_get_subscriptions()，可以使用较轻的SQL查询从特定的订单ID仅获取所需的订阅：

// Your targeted orders IDS (in a coma separated string, not an array)
$targeted_orders_ids = '123,456,789';

global $wpdb;

// get all subscriptions IDS
$subscriptions_ids = $wpdb->get_col( $wpdb->prepare( "
    SELECT ID  FROM {$wpdb->prefix}posts 
    WHERE post_type = 'shop_subscription'
    AND post_status = 'wc-active'
    AND post_parent IN %s;
", ) );

global $wpdb;

// The SQL query (get active subscriptions data from specific orders IDs)
$subscriptions_ids = $wpdb->get_col( $wpdb->prepare( "
    SELECT ID  FROM {$wpdb->prefix}posts
    WHERE post_type = 'shop_subscription'
    AND post_status = 'wc-active'
    AND post_parent IN (%s);
", $targeted_orders_ids ) );

// Loop through subscriptions Ids
foreach($subscriptions_ids as $subscription_id){
    // Get an instance of the WC_Subscription object
    $subscription = new WC_Subscription( $subscription_id );

    // Unprotected data in an accessible array
    $data = $subscription->get_data();

    // Get the shipping city
    $shipping_city = $data['shipping']['city'];

    echo '<p>' . $shipping_city . '</p>'; // Display the shipping city

    // print_r( $data ); // Display the subscription raw data array (if needed)
}
