Question

我想对WooCommerce主题进行一些更改，并更改“可变产品”下拉列表的显示方式。我想在此屏幕快照这样的下拉菜单中显示除变体值以外的每个变体的图像：

因此，我尝试编辑single-product/add-to-cart/variable.php模板文件代码以获取缩略图，但未返回任何内容：

<?php
$product = new WC_Product_Variable( $product_id );
$variations = $product->get_available_variations();

foreach ( $variations as $variation ) {
echo "<img src=" . $variation['image']['url'] .">";
}
?>

更新

这是我真正的Variable.php文件：

<?php

defined( 'ABSPATH' ) || exit;

global $product;

$attribute_keys = array_keys( $attributes );

do_action( 'woocommerce_before_add_to_cart_form' ); ?>

<form class="variations_form cart" action="<?php echo esc_url(     apply_filters( 'woocommerce_add_to_cart_form_action', $product->get_permalink() ) ); ?>" method="post" enctype='multipart/form-data' data-product_id="<?php echo absint( $product->get_id() ); ?>" data-product_variations="<?php echo htmlspecialchars( wp_json_encode( $available_variations ) ); // WPCS: XSS ok. ?>">
<?php do_action( 'woocommerce_before_variations_form' ); ?>

<?php if ( empty( $available_variations ) && false !== $available_variations ) : ?>
    <p class="stock out-of-stock"><?php esc_html_e( 'This product is currently out of stock and unavailable.', 'woocommerce' ); ?></p>
<?php else : ?>
    <table class="variations" cellspacing="0">
        <tbody>
                <tr>
                    <td colspan="2" class="alert-color is-bold"><?php _e( 'Please choose product options&hellip;', 'woocommerce' ); ?></td>
                </tr>
            <?php foreach ( $attributes as $attribute_name => $options ) : ?>
                <tr>
                    <td class="label"><label for="<?php echo esc_attr( sanitize_title( $attribute_name ) ); ?>"><?php echo wc_attribute_label( $attribute_name ); // WPCS: XSS ok. ?></label></td>
                    <td class="value">
                        <?php
                            wc_dropdown_variation_attribute_options( array(
                                'options'   => $options,
                                'attribute' => $attribute_name,
                                'product'   => $product,
                            ) );
                            echo end( $attribute_keys ) === $attribute_name ? wp_kses_post( apply_filters( 'woocommerce_reset_variations_link', '<a class="reset_variations" href="#">' . esc_html__( 'Clear', 'woocommerce' ) . '</a>' ) ) : '';
                        ?>
                    </td>
                </tr>
            <?php endforeach; ?>
        </tbody>
    </table>

    <div class="single_variation_wrap">
        <?php
            /**
             * Hook: woocommerce_before_single_variation.
             */
            do_action( 'woocommerce_before_single_variation' );

             */
            do_action( 'woocommerce_single_variation' );

            /**
             * Hook: woocommerce_after_single_variation.
             */
            do_action( 'woocommerce_after_single_variation' );
        ?>
    </div>
<?php endif; ?>

<?php do_action( 'woocommerce_after_variations_form' ); ?>
</form>

<?php
do_action( 'woocommerce_after_add_to_cart_form' );
