WooCommerce 如何在结帐页面上显示“您节省了 X%”

Question

我制作了一个功能，可以在结帐时根据产品折扣显示总节省，但我希望它显示高于订单总额的节省百分比，如果可能的话，将其显示在方框内。

代码：

function wc_discount_total() {
   global $woocommerce;
    $discount_total = 0;
      
    foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values) {
          
    $_product = $values['data'];
  
        if ( $_product->is_on_sale() ) {
        $regular_price = $_product->get_regular_price();
        $sale_price = $_product->get_sale_price();
        $discount = ($regular_price - $sale_price) * $values['quantity'];
        $discount_total += $discount;
        }
    }        
    if ( $discount_total > 0 ) {
    echo '<tr class="cart-discount">
    <th>'. __( 'Your Savings', 'woocommerce' ) .'</th>
    <td data-title=" '. __( 'You Saved', 'woocommerce' ) .' ">'
    . wc_price( $discount_total + $woocommerce->cart->discount_cart ) .'</td>
    </tr>';
    }
}
add_action( 'woocommerce_cart_totals_after_order_total', 'wc_discount_total', 99);
add_action( 'woocommerce_review_order_after_order_total', 'wc_discount_total', 99);

我当前的结帐方式如下：

我希望它看起来如何：

Answer 1

如果该订单有折扣，那么您可以添加另一个表格行标签并计算百分比。所以它会是这样的：

add_action('woocommerce_cart_totals_after_order_total', 'wc_discount_total', 99);

add_action('woocommerce_review_order_after_order_total', 'wc_discount_total', 99);

function wc_discount_total()
{
  global $woocommerce;
  $discount_total = 0;

  foreach ($woocommerce->cart->get_cart() as $cart_item_key => $values) {

    $_product = $values['data'];

    if ($_product->is_on_sale()) {
      $regular_price = $_product->get_regular_price();
      $sale_price = $_product->get_sale_price();
      $discount = ($regular_price - $sale_price) * $values['quantity'];
      $discount_total += $discount;
    }
  }
  if ($discount_total > 0) {
    echo '<tr class="cart-discount">
      <th>' . __('Your Savings', 'woocommerce') . '</th>
      <td data-title=" ' . __('You Saved', 'woocommerce') . ' ">'
      . wc_price($discount_total + $woocommerce->cart->discount_cart) . '</td>
      </tr>';

    $total = WC()->cart->cart_contents_total;
    $total_saved = wc_price($discount_total + $woocommerce->cart->discount_cart);
    $percentage_saved = round(($total_saved * 100) / $total);

    echo '<tr class="cart-percentage-discount">
      <th>' . __('Percentage Saved', 'woocommerce') . '</th>
      <td data-title=" ' . __('You Saved', 'woocommerce') . ' ">' . esc_html($percentage_saved . "%") . '</td>
      </tr>';
  }
}
