在 woodmart 迷你購物車小部件中添加簡單和可變產品的總重量-PHP中文網路問答

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：

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 .
