目前，woo commerce仅提供产品名称和数量框。我的一些产品是不同的颜色或风格。我希望客户能够看到作为分组产品的产品名称旁边的缩略图图像。如果可能的话，如果它们悬停在它上面看它更大。

找到了这个，但似乎无法正常工作
add_action( 'woocommerce_grouped_product_list_before_price', 'woocommerce_grouped_product_thumbnail' );
function woocommerce_grouped_product_thumbnail( $product ) {
$image_size = array( 20, 20 ); // array( width, height ) image size in pixel
$attachment_id = get_post_meta( $product->id, '_thumbnail_id', true );
?>
<td class="label">
<?php echo wp_get_attachment_image( $attachment_id, $image_size ); ?>
</td>
<?php
}
答案 0 :(得分：0)
我做到了！ 我以另一种方式使用此代码：
<?php
/**
* Grouped product add to cart
*
* @author WooThemes
* @package WooCommerce/Templates
* @version 2.1.7
*/
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
global $product, $post, $image_size;
$image_size = array( 50, 50 );// array( width, height ) image size in pixel
$parent_product_post = $post;
do_action( 'woocommerce_before_add_to_cart_form' ); ?>
<form class="cart" method="post" enctype='multipart/form-data'>
<table cellspacing="0" class="group_table">
<tbody>
<?php
foreach ( $grouped_products as $product_id ) :
$product = wc_get_product( $product_id );
if ( 'yes' === get_option( 'woocommerce_hide_out_of_stock_items' ) && ! $product->is_in_stock() ) {
continue;
}
$post = $product->post;
setup_postdata( $post );
?>
<tr>
<?php $attachment_id = get_post_meta( $product->id, '_thumbnail_id', true ); ?>
<td class="gpThumbs">
<?php echo wp_get_attachment_image( $attachment_id, $image_size ); ?>

<td class="label">
<label for="product-<?php echo $product_id; ?>">
<?php echo $product->is_visible() ? '<a href="' . get_permalink() . '">' . get_the_title() . '</a>' : get_the_title(); ?>
</label>
</td>
<?php do_action ( 'woocommerce_grouped_product_list_before_price', $product ); ?>
<td class="price">
<?php
echo $product->get_price_html();
if ( $availability = $product->get_availability() ) {
$availability_html = empty( $availability['availability'] ) ? '' : '<p class="stock ' . esc_attr( $availability['class'] ) . '">' . esc_html( $availability['availability'] ) . '</p>';
echo apply_filters( 'woocommerce_stock_html', $availability_html, $availability['availability'], $product );
}
?>
</td>
<td>
<?php if ( $product->is_sold_individually() || ! $product->is_purchasable() ) : ?>
<?php woocommerce_template_loop_add_to_cart(); ?>
<?php else : ?>
<?php

woocommerce_quantity_input( array( 'input_name' => 'quantity[' . $product_id .

?>
<?php endif; ?>
</td>
</tr>
<?php
endforeach;
// Reset to parent grouped product
$post = $parent_product_post;
$product = wc_get_product( $parent_product_post->ID );
setup_postdata( $parent_product_post );
?>
</tbody>
</table>
<input type="hidden" name="add-to-cart" value="<?php echo esc_attr( $product->id ); ?>" />
<?php if ( $quantites_required ) : ?>
<?php do_action( 'woocommerce_before_add_to_cart_button' ); ?>
<button type="submit" class="single_add_to_cart_button button alt"><?php echo $product->single_add_to_cart_text(); ?></button>

<?php endif; ?>

<?php do_action( 'woocommerce_after_add_to_cart_form' ); ?>
它运作良好：）
