如何在 WooCommerce 简码中定义产品以在自定义订单接收页面上使用

Question

根据我之前的问题为什么 WooCommerce Order Shortcode Generate Plugin Notice on CustomThank You Page？

通知消息已更改，现在它要求我定义产品。 这是通知：

Notice: Undefined variable: product in /wp-content/themes/storefront/functions.php on line 842

该通知指的是这一行：

'purchase_note' => $product ? $product->get_purchase_note() : '',

这是完整的代码：

function order_cost_breakdown(){

    if ( isset( $_GET['order_id']) && $_GET['order_id'] > 0 ) {

        $order_id = (int) esc_attr( $_GET['order_id'] );

        $order = wc_get_order( $order_id );

        $order_data = $order->get_data();

        $show_purchase_note    = $order->has_status( apply_filters( 'woocommerce_purchase_note_order_statuses', array( 'completed', 'processing' ) ) );

    ob_start();
    
    ?>

        <div class="woocommerce-account woocommerce-page"><div class="woocommerce">

            <table class="shop_table order_details">

                <thead>

                    <tr>
                        <th class="product-name"><?php _e( 'Product', 'woocommerce' ); ?></th>
                        <th class="product-total"><?php _e( 'Total', 'woocommerce' ); ?></th>

                    </tr>

                </thead>

            <tbody>

        <?php foreach ( $order->get_items() as $item_id => $item ) {

        wc_get_template( 'order/order-details-item.php', array (
        'order' => $order,
        'item_id' => $item_id,
        'item' => $item,
        'product' => apply_filters( 'woocommerce_order_item_product', $item->get_product( $item ), $item ),
        'show_purchase_note' => $show_purchase_note,
        'purchase_note' => $product ? $product->get_purchase_note() : '',
        ) );
        }
    ?>

    <?php do_action( 'woocommerce_order_items_table', $order ); ?>

            </tbody>
        
        <tfoot>

    <?php

        foreach ( $order->get_order_item_totals() as $key => $total ){
    ?>

    <tr>
    
        <th scope="row"><?php echo $total['label']; ?></th>
        <td><?php echo $total['value']; ?></td>
    </tr>

        <?php
    }

    ?>
            </tfoot>
    
        </table>
    
    </div>

</div>

<?php

    return ob_get_clean();
    
    }

}

任何建议都是有帮助的，因为我显然不是专家。

修复通知

代替

<?php foreach ( $order->get_items() as $item_id => $item ) {

    wc_get_template( 'order/order-details-item.php', array (
    'order' => $order,
    'item_id' => $item_id,
    'item' => $item,
    'product' => apply_filters( 'woocommerce_order_item_product', $item->get_product( $item ), $item ),
    'show_purchase_note' => $show_purchase_note,
    'purchase_note' => $product ? $product->get_purchase_note() : '',
    ) );
    }
?>

和

<?php foreach ( $order->get_items() as $item_id => $item ) {
    $product = $item->get_product();

    wc_get_template( 'order/order-details-item.php', array (
        'order'              => $order,
        'item_id'            => $item_id,
        'item'               => $item,
        'product'            => apply_filters( 'woocommerce_order_item_product', $item->get_product( $item ), $item ),
        'show_purchase_note' => $show_purchase_note,
        'purchase_note'      => $product ? $product->get_purchase_note() : '',
    ));
}       
?>

这应该足够了
