我创建了一个在线表单，其中输入数据使用 PHPMailer 通过电子邮件发送。然而，我目前收到的电子邮件显示的是变量，而不是用户在表单中实际输入的内容。这是我刚刚收到的一封电子邮件的示例：
Account Name: $AccountName
Delivery To: $DeliveryTo
Order No: $OrderNo
Del Date: $DelDate
Builder Name: $BuilderName
Delivery Instructions: $DeliveryInstructions
Contact Phone: $ContactPhone
请注意，即使我输入了帐户名称、电话号码等内容，但变量名称（$AccountName、$ContactPhone）正在显示，而不是实际输入。我已经设置了这些变量，如下所示，所以我不确定为什么会这样。任何帮助将不胜感激。
在我的 mail.php 中：
<?php
require("/home/ange/public_html/angelasmith.com.au/staging/PHPMailer_5.2.2/class.phpmailer.php");
$AccountName = $_POST['AccountName'];
$DeliveryTo = $_POST['DeliveryTo'];
$OrderNo = $_POST['OrderNo'];
$DelDate = $_POST['DelDate'];
$BuilderName = $_POST['BuilderName'];
$DeliveryInstructions = $_POST['DeliveryInstructions'];
$ContactPhone = $_POST['ContactPhone'];
$totalsheets = $_POST['totalsheets'];
$totalsqm = $_POST['totalsqm'];
$c15 = $_POST['c15'];
$d15 = $_POST['d15'];
$e15 = $_POST['e15'];
$f15 = $_POST['f15'];
$h15 = $_POST['h15'];
$i15 = $_POST['i15'];
$j15 = $_POST['j15'];
$k15 = $_POST['k15'];
$l15 = $_POST['l15'];
$m15 = $_POST['m15'];
$c16 = $_POST['c16'];
$d16 = $_POST['d16'];
$e16 = $_POST['e16'];
$f16 = $_POST['f16'];
$h16 = $_POST['h16'];
$i16 = $_POST['i16'];
$j16 = $_POST['j16'];
$k16 = $_POST['k16'];
$l16 = $_POST['l16'];
$m16 = $_POST['m16'];
$mail = new PHPMailer();
$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "mail.mydomain.com.au"; // specify main and backup server
$mail->Port = 25;
$mail->Username = "test@mydomain.com.au"; // SMTP username
