如何計算電子商務中的線路總數

Question

如何使用優惠券代碼20 rs off和6％的稅率來計算在uoo commerce中創建訂單的線路總數。

$order = new WC_Order(); 
$order = wc_create_order($order_data); 

$items = WC()->cart->get_cart(); 

foreach($items as $item => $values) { 
    $product_id = $values['product_id']; 
    $product = wc_get_product($product_id); 
    $quantity = (int)$values['quantity']; 

    $sale_price = $product->get_price(); 
    $final_price = ????? 
    $price_params = array('totals' => array('subtotal' => $sale_price, 'total' => $final_price)); 
    $order->add_product($product, $quantity,$price_params); 
} 

這裏我怎樣才能得到$ final_price？

Answer 1

我想你可以做這樣的事情

$order = new WC_Order(); 
$order = wc_create_order($order_data); 

$items = WC()->cart->get_cart(); 

foreach($items as $item => $values) { 
    $product_id = $values['product_id']; 
    $product = wc_get_product($product_id); 
    $quantity = (int)$values['quantity']; 

    $sale_price = $product->get_price(); 
    $final_price = ????? 
    $price_params = array('totals' => array('subtotal' => $sale_price, 'total' => $final_price)); 
    $order->add_product($product, $quantity,$price_params); 
} 
$order_total=WC()->cart->calculate_totals(); 

Answer 2

嘗試這個

public function get_line_total($item, $inc_tax = false, $round = true) { 
    $total = 0; 

    if (is_callable(array($item, 'get_total'))) { 
     // Check if we need to add line tax to the line total. 
     $total = $inc_tax ? $item->get_total() + $item->get_total_tax() : $item->get_total(); 

     // Check if we need to round. 
     $total = $round ? round($total, wc_get_price_decimals()) : $total; 
    } 

    return apply_filters('woocommerce_order_amount_line_total', $total, $this, $item, $inc_tax, $round); 
    }
