我正在使用Woocommerce与动态图库PRO 。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，它是显示的主要产品图像，而不是变化图像。据我所知，Gallery插件使用结帐页面的第一个图像来显示。
我已经在Woocommerce的email-order-details.php中将'$show_image'变为true。
我应编辑的代码文件（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？我不是一个真正的程序员，但我一路上学到了很多东西。
答案 0 :(得分：2)
在 @ $ show_image 附近试试这个，它为我工作。
选项1：
echo $order->email_order_items_table( true, false, true, true, array(80,48) );
选项2：
echo $_product->get_image();
