Question

从这个PHP脚本。我愿意在最后总价格上加10％的折扣。请帮帮我，我不知道为什么如何在这个插件中添加折扣功能

// Calculate Total Price
$total_price = $book_room_price * $total_stay;

// Get currency unit stored in the theme options
if ( $data['currency_unit'] !== '' ) {
    $currency_unit = $data['currency_unit'];

Answer 1

// Calculate Total Price
$discount = 10;
$total_price = $book_room_price * $total_stay;
$discounted_total = $total_price - ($total_price * ($discount/100)); 

 // Get currency unit stored in the theme options
if ( $data['currency_unit'] !== '' ) {
$currency_unit = $data['currency_unit'];

Answer 2

您可以使用以下格式：

// Calculate Total Price
$total_price = $book_room_price * $total_stay;

$total_price = $total_price * 0.9;

// Get currency unit stored in the theme options
if ( $data['currency_unit'] !== '' ) {
    $currency_unit = $data['currency_unit'];

对于％10 = 0.9

对于％15 = 0.85

对于％20 = 0.8

在最终总价中添加10％的折扣
