我正在使用 Woodmart 主题和迷你购物车小部件，我想显示简单和可变产品的总重量和总价格。 所以我修改了代码，但它不起作用并且存在以下问题：
<强>1。 （总重量）：当简单或可变产品添加到购物车时，总重量显示为产品重量的一半。例如，如果产品重量设置为 0.5 ，当添加到购物车时，迷你购物车上的总重量显示为 0.25。
<强>2。 （总价）：当简单或可变产品添加到购物车时，总价显示为产品价格的一半。例如，如果基于重量 (0.5) 的产品价格为 7500，当添加到购物车时，迷你购物车上的总价显示为 3750。
感谢任何帮助。非常感谢。 这是我的代码：
1
1111/* Display the total weight in the mini cart shopping cart widget footer*/
function display_mini_cart_total_weight() {
if ( ! WC()->cart->is_empty() ) {
$total_weight = 0;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$product = $cart_item['data'];
$variation_id = $cart_item['variation_id'];
$weight = 0;
if ( $variation_id ) {
// Get the selected variation
$variation = wc_get_product( $variation_id );
if ( $variation ) {
// Get the weight of the variation
$weight = $variation->get_weight();
}
} else {
// Get the weight of the product
$weight = $product->get_weight();
}
$quantity = $cart_item['quantity'];
// Calculate the weight for the current product
$product_weight = $weight * $quantity;
// Add the product's weight to the total weight
$total_weight += $product_weight;
}
// Output the total weight in the mini cart shopping cart widget footer
$total_weight_display = $total_weight . ' Kg'; // Append ' Kg' to the total weight
echo '<tr class="total-weight-row">
<td colspan="3" class="total-weight-cell">
<p class="total-weight-label woocommerce-mini-cart__total">' . __('Total Weight:', 'chahar-4-rahewordpress') . '</p>
<p class="total-weight-value woocommerce-Price-amount amount">' . $total_weight_display . '</p>
</td>
</tr>';
}
}
add_action( 'woocommerce_widget_shopping_cart_before_buttons', 'display_mini_cart_total_weight' );

您可以检查数量是否小于 1，则必须将最小数量视为 1。请检查以下代码。
