在 WooCommerce 中，我使用 Advanced Custom Fields 插件來顯示名為“product_cart_image”的自定義字段（圖像），它替換了購物車中產品的默認圖像。該代碼適用于簡單產品，但不適用于可變產品。對于這些，我得到了默認圖像。以下代碼進入cart.php模板文件：foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) { $_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key ); $product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key ); ?> <span class="product-thumbnail"> <?php $product_image = $_product->get_image(); $product_cart_image = get_field('product_cart_image', $_product->get_id()); if ( ! empty ( $product_cart_image ) ) { $product_image = wp_get_attachment_image( $product_cart_image['ID'] ); } $thumbnail = apply_filters( 'woocommerce_cart_item_thumbnail', $product_image, $cart_item, $cart_item_key ); if ( ! $product_permalink ) { echo $thumbnail; } else { printf( '<a href="%s">%s</a>', esc_url( $product_permalink ), $thumbnail ); } ?> </span> <?php}我怎樣才能讓它也適用于可變產品？

將可變產品添加到購物車時，對于購物車項目 cart，您需要獲取可變產品 ID 而不是變體 ID，因此您將替換以下行：
$product_cart_image = get_field('product_cart_image', $_product->get_id());
經過：
$product_cart_image = get_field('product_cart_image', $cart_item['product_id']);
現在它應該可以工作了……所以在你的代碼中：
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
$product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
?>
<span class="product-thumbnail">
<?php
$product_image = $_product->get_image();
$product_cart_image = get_field('product_cart_image', $cart_item['product_id']);
if ( ! empty ( $product_cart_image ) ) {
$product_image = wp_get_attachment_image( $product_cart_image['ID'] );
}
$thumbnail = apply_filters( 'woocommerce_cart_item_thumbnail', $product_image, $cart_item, $cart_item_key );
if ( ! $product_permalink ) {
echo $thumbnail;
} else {
printf( '<a href="%s">%s</a>', esc_url( $product_permalink ), $thumbnail );
}
?>
</span>
<?php
}
