WooCommerce订阅 - 检查产品是否已有活跃订阅者

Question

我正在使用插件"WooCommerce订阅",我想检查产品是否已在系统中拥有活动订阅者

我只想要每个产品1个订阅者.有一个过滤器可供检查,但我不知道如何使用它:https:
//docs.woocommerce.com/document/subscriptions/develop/filter-reference/

我怎样才能使用这些功能或钩子来实现这一目标？

谢谢

true如果订阅者已经积极使用订阅产品,则此定制条件函数将返回.

function has_an_active_subscriber( $product_id = null ){

    // Empty array to store ALL existing Subscription PRODUCTS
    $products_arr = array();


    $products_subscr = get_posts( array(
        'numberposts' => -1,
        'post_status' => 'publish',
        'post_type'   => array( 'product', 'product_variation' ),
        'meta_key' => '_subscription_price',
    ) );
    foreach( $products_subscr as $prod_subs ) {
        $products_arr[] = $prod_subs->ID;
    }

    // Testing if current product is a subscription product
    if (in_array( $product_id, $products_arr) ){

        // Declaring empties arrays
        $subscribers_arr = array(); // ALL subscribers IDS
        $active_subscriptions_arr = array(); // ALL actives subscriptions
        $active_subscription_products_arr = array(); // ALL actif subscription products IDS IDS
        $subscriber_subscriptions = array();

        // Getting arrays of "active" IDS for subscribers, subscriptions orders and subscription products
        $subscribers = get_users( array( 'role' => 'subscriber') );
        foreach( $subscribers as $subscriber ) {
            $subscriber_arr[] = $subscriber->ID;
            $subscriptions = wcs_get_users_subscriptions($subscriber->ID);
            foreach ($subscriptions as  $key => $subscription ){
                $subscription_status = $subscription->post->post_status;
                if ( $subscription_status == 'wc-active' ) { // active subscriptions only
                    $subscription_id = $subscription->post->ID;
                    $order_id = $subscription->order->post->ID; // order ID (corresponding to the subscription ID)
                    $active_subscriptions_arr[] = $subscription->post->ID;
                    $order_items = $subscription->order->get_items();
                    // Getting all the products in the Order
                    foreach ( $order_items as $item ) {
                        // $item_id = $item[product_id];

                        // Avoiding to add existing products in the array 
                        if( !in_array( $product_id, $active_subscription_products_arr ))
                            $active_subscription_products_arr[] = $item[product_id];
                    }
                }
            }
        }
    }
    if (in_array( $product_id, $active_subscription_products_arr ) ) return true;
    else return false;
}

此代码在您的活动子主题(或主题)的function.php上或在任何插件文件上.

我刚刚在这里使用了wcs_get_users_subscriptions()本机订阅功能,在我的代码中获取已定义用户ID的订阅.

USAGE (对于定义的$ product_id变量)

If ( has_an_active_subscriber( $product->id ) ) { // or $product_id
    // This product is already used by an active subscriber
    // DO SOMETHING HERE
} else {
    // This product is NOT used
    // DO SOMETHING HERE
}

您也可以$product_id在此处替换产品ID,例如,如果产品的ID是124):

If ( has_an_active_subscriber( 124 ) )  //do something

您可以使用此条件函数,特别是(订阅)模板(您必须从订阅插件模板文件夹复制到您的活动主题的woocommerce模板文件夹 ...)add-to-cart

所有代码都经过测试并且功能齐全
