WooCommerce我的帳戶頁面 - 獲取當前用戶的訂單查詢

Question

我試圖總結每個用戶的具體項目，但它似乎無法識別當前用戶，它彙總了所有客戶的所有訂單。

我該如何解決這個問題？我錯過了什麼？

下面是我使用的代碼：

$order_items = apply_filters('woocommerce_reports_top_earners_order_items', $wpdb->get_results(" 

SELECT order_item_meta_2.meta_value as product_id, SUM(order_item_meta.meta_value) as line_total FROM {$wpdb->prefix}woocommerce_order_items as order_items 

LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id 

LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta_2 ON order_items.order_item_id = order_item_meta_2.order_item_id 

LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID 

WHERE posts.post_type = 'shop_order' 

AND posts.post_status IN ('" . implode("','", array('wc-completed', 'wc-processing', 'wc-on-hold')) . "') 

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 

")); 
$totalPR = 0; 
$Products = array(1507, 1406, 1506); 

foreach ($order_items as $item) { 

if (in_array($item->product_id, $Products)) { 

     $totalPR = $item->line_total + $totalPR; 
     echo $totalPR; 

    } 

}

更新2 - 它的工作使這個：

1. 獲取客戶名單
2. 在foreach遍歷每個客戶迴路
3. 取得客戶編號

4. 添加LEFT JOIN爲wp_postmeta表上POST_ID：

   LEFT JOIN {$wpdb->postmeta} AS postmeta ON order_items.order_id = postmeta.post_id 
   

5. 插入此2號線到您的WHERE：

   AND postmeta.meta_key = '_customer_user' 
   
   AND postmeta.meta_value = '$customer_id' 
   

6. 然後是客戶循環內的循環，通過得到的總和客戶

這是代碼：

global $wpdb; 

// Set here your product ids 
$products = array(1507, 1406, 1506); 
$all_customers = get_users('role=customer'); 

foreach ($all_customers as $customer) { 
    $customer_id = $customer->ID; 
    $total_pr = 0; 

    $query = $wpdb->get_results(" 

     SELECT order_item_meta_2.meta_value as product_id, 

     SUM(order_item_meta.meta_value) as line_total 

     FROM {$wpdb->prefix}woocommerce_order_items as order_items 

     LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id 

     LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta_2 ON order_items.order_item_id = order_item_meta_2.order_item_id 

     LEFT JOIN {$wpdb->postmeta} AS postmeta ON order_items.order_id = postmeta.post_id 

     LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID 

     WHERE posts.post_type = 'shop_order' 

     AND posts.post_status IN ('" . implode("','", array('wc-completed', 'wc-processing', 'wc-on-hold')) . "') 

     AND postmeta.meta_key = '_customer_user' 

     AND postmeta.meta_value = '$customer_id' 

     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 

    "); 

    $results = apply_filters('woocommerce_reports_top_earners_order_items', $query); 

    foreach ($results as $values) { 
     if (in_array($values->product_id, $products)) { 
      $total_pr += $values->line_total; 
     } 
    } 
    echo 'customer ID: ' . $customer->ID . ' | Total PR: ' . number_format($total_pr, 2) . '<br>'; 
} 

測試和工程。它將輸出列表與Customer IDs和相應的Total PR。
