WP查询按日期的总销售额订购WooCommerce产品

Question

我想退回WooCommerce中从特定日期开始按受欢迎程度（总销售额）排序的所有产品。

$args = array(
  'post_type' => 'products',
  'posts_per_page' => 2000,
  'orderby'   => 'meta_value_num',
  'meta_key'  => 'total_sales',
  'order' => 'desc',
  'date_query' => array(
      'column' => 'order_date',
      array(
        'after' => 'April 1st 2017',
      ),
  ),
);
$products =  new WP_Query( $args );
if ( $products->have_posts() ) {
  while ( $products->have_posts() ) : $products->the_post();
    the_title();
    echo '<br>';
  endwhile;
}

此查询返回自 April 1st 2017 年以来按受欢迎程度排序的所有产品，而不是自 April 1st 2017 年以来的产品总销售额。

Answer 1

看起来你的post_type对你想要的来说是错误的。

您正在查询product，而是应该shop_order：

$args = array(
  'post_type' => 'shop_order',
  'posts_per_page' => 2000,
  'orderby'   => 'meta_value_num',
  'meta_key'  => 'total_sales',
  'order' => 'desc',
  'date_query' => array(
      'column' => 'order_date',
      array(
        'after' => 'April 1st 2017',
      ),
  ),
);

您可以使用以下查询获得特定日期之间的最畅销产品：

 $query_str = "SELECT order_item_meta_2.meta_value as product_id, SUM( order_item_meta.meta_value ) as line_total 
        FROM wpfi_woocommerce_order_items as order_items
        LEFT JOIN wpfi_woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
        LEFT JOIN wpfi_woocommerce_order_itemmeta as order_item_meta_2 ON order_items.order_item_id = order_item_meta_2.order_item_id
        LEFT JOIN wpfi_posts AS posts ON order_items.order_id = posts.ID
        WHERE posts.post_type = 'shop_order'
        AND posts.post_date BETWEEN '".$previous_date."' AND '".$current_date."'
        AND posts.post_status IN ( 'wc-completed') 
        AND order_items.order_item_type = 'line_item'
        AND order_item_meta.meta_key = '_line_total'
        AND order_item_meta_2.meta_key = '_product_id'
        GROUP BY order_item_meta_2.meta_value LIMIT 5";

Answer 3

我认为你必须使用post_type=order。

$args = array(
  'post_type' => 'shop_order',
  'posts_per_page' => 2000,
  'orderby'   => 'meta_value_num',
  'meta_key'  => 'order_total',
  'order' => 'desc',
  'date_query' => array(
      'column' => 'post_date',
      array(
        'after' => 'April 1st 2017',
      ),
  ),
);
