WC_Orderはget_items（でプロダクトIDを返しません）

Question

：私は、製品の名前を得た上記のコードで

if ($query->have_posts()) { 
    $order_id = $query->posts[0]->ID; 
    $order = new WC_Order($order_id); 
    $items = $order->get_items(); 
} 

    foreach ($items as $item) { 
     $product_id = $item['product_id']; 
     $product = wc_get_product($item_id); 
     $product_name = $item['name']; 
    } 

が、 $ product_idの場合は0が返されます。これには他の方法がありますか？

は、[データ：保護]を参照してください。私はこの配列だ

$order_id = $query->posts[0]->ID; 
$order = new WC_Order($order_id); 
$items = $order->get_items(); 

foreach ($items as $item) { 
    $item_id = $item['product_id']; 
    $product_name = $item['name']; 
    print_r($item); exit; 
} 

を配列し、あなたが見ることができますこれは[product_id]が0であるところです。それは私が推測する問題です。しかし、これのための解決策は何ですか？

Answer 1

それは次のようになります。

foreach ($items as $item) { 
    $product = $item->get_product(); 
    $product_id = $product->get_id(); 
}
