尝试将WooCommerce订阅创建为管理员时出错

Question

我正在尝试在WooCommerce中手动添加一个订阅，并不断地得到这个错误。

我已经找到了PHP文件，但不确定是否存在错误。任何帮助都将不胜感激。谢谢。

致命错误:第128行的/nas/content/live/montkdev/wp-content/plugins/woocommerce-subscriptions/includes/data-stores/class-wcs-customer-store-cached-cpt.php中不支持[]操作符

Answer 1

WCS在行$subscription_ids[] = $subscription_id;中的函数中存在此问题。

/**
 * Add a subscription ID to the cached subscriptions for a given user.
 *
 * @param int $user_id The user the subscription belongs to.
 * @param int $subscription_id A subscription to link the user in the cache.
 */
protected function add_subscription_id_to_cache( $user_id, $subscription_id ) {

    $subscription_ids = $this->get_users_subscription_ids( $user_id );

    if ( ! in_array( $subscription_id, $subscription_ids ) ) {
        $subscription_ids[] = $subscription_id;
        $this->update_subscription_id_cache( $user_id, $subscription_ids );
    }
}

如果问题仍然存在，请尝试添加以下代码片段，同时添加订阅。

remove_all_actions('wcs_update_post_meta_caches');
