如果您有自定義訂單狀態，然後又發現用 get_posts function 怎麼樣都抓不到想要的訂單列表的話，這段code 可能就對你有用拉！很奇怪的，我用以下這段 code 怎麼都撈不出訂單。

$post_status_list = array_merge(array_keys( Ecpay_get_order_statuses() ), array_keys( wc_get_order_statuses() ));

$customer_orders = get_posts( apply_filters( 'woocommerce_my_account_my_orders_query', array(
	'numberposts' => $order_count,
	'meta_key'    => '_customer_user',
	'meta_value'  => get_current_user_id(),
	'post_type'   => wc_get_order_types( 'view-orders' ),
	'post_status' => $post_status_list
) ) );

其中 Ecpay_get_order_statuses 是我參考 wc_get_order_statuses 幫 ecpay 定義的訂單狀態。內容如下，

function Ecpay_get_order_statuses(){
  
  $order_statuses = array(
		'wc-ecpay'    => _x( '訂單已成立出貨中', 'Order status', 'woocommerce' ),
		'wc-ecpay-send' => _x( '賣家已到門市寄件', 'Order status', 'woocommerce' ),
		'wc-ecpay-receive'    => _x( '商品已送達您指定的門市', 'Order status', 'woocommerce' ),
		'wc-ecpay-finish'  => _x( '消費者成功取件', 'Order status', 'woocommerce' ),
		'wc-ecpay-fail'  => _x( '消費者七天未取件', 'Order status', 'woocommerce' ),		
	);
  
  return $order_statuses;
  
}

後來只好直接透過 wpdb ，直接進行 db 操作，來解決這個弔詭的問題了。

$post_status_list = array_merge(array_keys( Ecpay_get_order_statuses() ), array_keys( wc_get_order_statuses() ));

global $wpdb;

$post_status = implode("','", $post_status_list);
$user_id = get_current_user_id();


$customer_orders = $wpdb->get_results( "SELECT p.* FROM $wpdb->postmeta pm, $wpdb->posts p
          where p.post_type = 'shop_order' 
          and post_status IN ('{$post_status}')
          and pm.meta_key = '_customer_user' 
          and pm.meta_value = {$user_id}    
          and pm.post_id = p.ID
          order by post_date desc
        ");
