php - Woocommerce 变体产品图片未显示在订单电子邮件中

Question

我将 Woocommerce 与 Dynamic Gallery PRO 结合使用。产品页面上的图像工作正常，我还设法在发送给管理员和客户的电子邮件中显示产品图像。但是，显示的是主要产品图像，而不是变体图像。据我了解，图库插件使用第一个图像来显示结帐页面。

我已经在 Woocommerce 的 email-order-details.php 中将 '$show_image' 设置为 true。

我应该编辑的代码文档(我认为)如下:

<?php

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

foreach ( $items as $item_id => $item ) :
    $_product     = apply_filters( 'woocommerce_order_item_product', $order->get_product_from_item( $item ), $item );
    $item_meta    = new WC_Order_Item_Meta( $item, $_product );

    if ( apply_filters( 'woocommerce_order_item_visible', true, $item ) ) {
        ?>
        <tr class="<?php echo esc_attr( apply_filters( 'woocommerce_order_item_class', 'order_item', $item, $order ) ); ?>">
            <td class="td" style="text-align:left; vertical-align:middle; border: 1px solid #eee; font-family: 'Helvetica Neue', Helvetica, Roboto, Arial, sans-serif; word-wrap:break-word;"><?php

                // Show title/image etc
                **if ( $show_image ) {
                    echo apply_filters( 'woocommerce_order_item_thumbnail', '<div style="margin-bottom: 5px"><img src="' . ( $_product->get_image_id() ? current( wp_get_attachment_image_src( $_product->get_image_id(), 'thumbnail') ) : wc_placeholder_img_src() ) .'" alt="' . esc_attr__( 'Product Image', 'woocommerce' ) . '" height="' . esc_attr( $image_size[1] ) . '" width="' . esc_attr( $image_size[0] ) . '" style="vertical-align:middle; margin-right: 10px;" /></div>', $item );
                }**

                // Product name
                echo apply_filters( 'woocommerce_order_item_name', $item['name'], $item, false );

                // SKU
                if ( $show_sku && is_object( $_product ) && $_product->get_sku() ) {
                    echo ' (#' . $_product->get_sku() . ')';
                }

                // allow other plugins to add additional product information here
                do_action( 'woocommerce_order_item_meta_start', $item_id, $item, $order, $plain_text );

                // Variation
                if ( ! empty( $item_meta->meta ) ) {
                    echo '<br/><small>' . nl2br( $item_meta->display( true, true, '_', "\n" ) ) . '</small>';
                }

                // File URLs
                if ( $show_download_links ) {
                    $order->display_item_downloads( $item );
                }

                // allow other plugins to add additional product information here
                do_action( 'woocommerce_order_item_meta_end', $item_id, $item, $order, $plain_text );

            ?></td>
            <td class="td" style="text-align:left; vertical-align:middle; border: 1px solid #eee; font-family: 'Helvetica Neue', Helvetica, Roboto, Arial, sans-serif;"><?php echo apply_filters( 'woocommerce_email_order_item_quantity', $item['qty'], $item ); ?></td>
            <td class="td" style="text-align:left; vertical-align:middle; border: 1px solid #eee; font-family: 'Helvetica Neue', Helvetica, Roboto, Arial, sans-serif;"><?php echo $order->get_formatted_line_subtotal( $item ); ?></td>
        </tr>
        <?php
    }

    if ( $show_purchase_note && is_object( $_product ) && ( $purchase_note = get_post_meta( $_product->id, '_purchase_note', true ) ) ) : ?>
        <tr>
            <td colspan="3" style="text-align:left; vertical-align:middle; border: 1px solid #eee; font-family: 'Helvetica Neue', Helvetica, Roboto, Arial, sans-serif;"><?php echo wpautop( do_shortcode( wp_kses_post( $purchase_note ) ) ); ?></td>
        </tr>
    <?php endif; ?>

<?php endforeach; ?>

Gallery PRO定义图像的文件如下:

有人熟悉这个问题吗？我并不是真正的程序员，但我一路上学到了很多东西。

Answer 1

试试@$show_image附近的这个，它对我有用。

选项 1:

echo $order->email_order_items_table( true, false, true, true, array(80,48) );

选项 2:

echo $_product->get_image();
