php - 尝试使用 PHP 在电子邮件主题行中显示两个连接变量

Question

我试图通过 mailer.php 页面在主题行中显示两个连接变量，但电子邮件中的主题行始终为空白。下面是相关代码。

/* Subject and To */

$to = 'nnorman@dimplexthermal.com';
$subject = $company . ' ' . $name;

/* Gathering Data Variables */

$name = $_POST['name'];
$email = $_POST['email'];
$company = $_POST['company'];

$body = <<<EOD
<br><hr><br>
Email: $email <br>
Name: $name <br>
Company: $company <br>

EOD;

$headers = "From: $email\r\n";
$headers .= "Content-type: text/html\r\n";
$success = mail($to, $subject, $body, $headers);

Answer 1

$to = 'nnorman@dimplexthermal.com';
$subject = $company . ' ' . $name;

/* Gathering Data Variables */

$name = $_POST['name'];
$email = $_POST['email'];
$company = $_POST['company'];

你没有设置$company，$name直到你使用它们之后$subject

尝试换行：

/* Gathering Data Variables */

$name = $_POST['name'];
$email = $_POST['email'];
$company = $_POST['company'];

$to = 'nnorman@dimplexthermal.com';
$subject = $company . ' ' . $name;
