计算器脚本php

Question

我正在尝试构建我的第一个脚本，唯一挂起的就是我试图将某些东西乘以1.7。因此，当输入值时，我希望将其乘以1.7，然后将结果发送到电子邮件中。有人能帮上忙吗。

我正在建立一个在线家具清单供客户填写，然后所有的结果+立方米将电子邮件给我。所以有很多剧本要我写，我想我已经想好了剩下的。下面是我只能上大床的剧本的一部分，这就是我想要的，乘以1.7，预先感谢：)

/* Data Variables */

$email = $_POST['email'];
$name = $_POST['name'];
$phone = $_POST['phone'];
$uplift = $_POST['uplift'];
$city = $_POST['city'];
$post = $_POST['post'];
$delivery = $_POST['delivery'];
$city2 = $_POST['city2'];
$post2 = $_POST['post2'];
$ground = $_POST['ground'];
$second = $_POST['second'];
$second2 = $_POST['second2'];
$ground2 = $_POST['ground2'];
$queen = $_POST['queen'];





$body = <<<EOD
<br><hr><br>
Name: $name <br>  
Email: $email <br>
Phone; $phone <br>
<br>
Uplift; $uplift <br>
City; $city <br>
Post Code; $post <br>
<br>
Delivery Address; $delivery <br>  
City; $city2 <br>
Post; $post2 <br>  
<br>
Uplift; <br>
Ground Floor; $ground <br>
Second Floor; $second <br>
<br>
Delivery; <br>
Ground Floor; $ground2 <br>
Second Floor; $second2 <br>
Queen Bed; $queen <br>

Answer 1

你能做到的

//$queen is POST value
$queen = $_POST['queen'];

//$queenMulti is value of $queen x 1.7, $queen will be still the post value.
$queenMulti = $queen * 1.7;
