在 woodmart 迷你購物車小部件中添加簡單和可變產品的總重量

Question

我正在使用 Woodmart 主題和迷你購物車小部件，我想顯示簡單和可變產品的總重量和總價格。 所以我修改了程式碼，但它不起作用並且有以下問題：

<強>1。 （總重量）：當簡單或可變產品添加到購物車時，總重量顯示為產品重量的一半。例如，如果產品重量設定為 0.5 ，當加入購物車時，迷你購物車上的總重量顯示為 0.25。

<強>2。 （總價）：當簡單或可變產品添加到購物車時，總價顯示為產品價格的一半。例如，如果基於重量 (0.5) 的產品價格為 7500，當添加到購物車時，迷你購物車上的總價顯示為 3750。

感謝任何幫助。非常感謝。 這是我的程式碼：

/* 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' );

您可以檢查數量是否小於 1，則必須將最小數量視為 1。請檢查以下程式碼。

/* Display the total weight and price in the mini cart shopping cart widget footer */
function display_mini_cart_total_weight() {
    if ( ! WC()->cart->is_empty() ) {
        $total_weight = 0;
        $total_price = 0;

        foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
            $weight = 0;
            $price = 0;
            $product = $cart_item['data'];
            $variation_id = $cart_item['variation_id'];

            if ( $variation_id ) {
                // Get the selected variation
                $variation = wc_get_product( $variation_id );

                if ( $variation ) {
                    // Get the weight and price of the variation
                    $weight = $variation->get_weight();
                    $price = $variation->get_price();
                }
            } else {
                // Get the weight and price of the product
                $weight = $product->get_weight();
                $price = $product->get_price();
            }

            $quantity = $cart_item['quantity'];

            if( $quantity < 1 ){
                $quantity = 1;
            }

            // Calculate the weight and price of the current product
            $product_weight = $weight * $quantity;
            $product_price = $price * $quantity;

            // Add the product's weight and price to the total weight and price
            $total_weight += $product_weight;
            $total_price += $product_price;
        }

        // Output the total weight and price in the mini cart shopping cart widget footer
        $total_weight_display = $total_weight . ' Kg'; // Append ' Kg' to the total weight
        $total_price_display = wc_price( $total_price ); // Format the total price as WooCommerce price

        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>';

        echo '<tr class="total-price-row">
                <td colspan="3" class="total-price-cell">
                    <p class="total-price-label woocommerce-mini-cart__total">' . __('Total Price 1:', 'chahar-4-rahewordpress') . '</p>
                    <p class="total-price-value woocommerce-Price-amount amount">' . $total_price_display . '</p>
                </td>
            </tr>';
    }
}

add_action( 'woocommerce_widget_shopping_cart_before_buttons', 'display_mini_cart_total_weight' );
