如何按订单状态筛选

Question

我在 Wordpress 上使用 WooCommerce，现在一个名为 Parcelware 的插件允许我导出两个日期之间的任何订单，请参见下面的代码。我需要添加一个过滤器，这意味着只导出“处理”订单。

如果有人可以帮助我，那就太好了！

我在 WooCommerce 上找到此链接，不确定是否有任何帮助。

    return implode( self::$separator, $this->variables );
}

订单状态是一种分类，因此以下内容应为您过滤：

static function get_orders( $date_from, $date_to ){
    // Get orders between the two defined dates, this function uses a filter.
    define('PARCELWARE_GET_ORDERS_FILTER_DATE_FROM', $date_from );
    define('PARCELWARE_GET_ORDERS_FILTER_DATE_TO', $date_to );
    add_filter('posts_where', array( __CLASS__, 'order_page_get_orders_where_dates_between') );
    $orders = get_posts( array(
        'numberposts' => -1,
        'offset' => 0,
        'orderby' => 'post_date',
        'order' => 'DESC',
        'post_type' => 'shop_order',
        'suppress_filters' => false,
        'tax_query' => array(
                array(
                    'taxonomy' => 'shop_order_status',
                    'field' => 'slug',
                    'terms' => array('processing')
                )
            )
    ) );
    remove_filter('posts_where', 'order_page_get_orders_where_dates_between');

    return $orders;
}
