尝试使用PHP在电子邮件主题行中显示两个连接变量
问题描述：
I am trying to display two concatenated variables in a subject line through an mailer.php page, but the subject line in the email always comes in blank. Below is the pertinent code.
/* 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
";
$headers .= "Content-type: text/html
";
$success = mail($to, $subject, $body, $headers);
我试图通过mailer.php页面在主题行中显示两个连接变量，但主题行在 电子邮件总是空白。 以下是相关代码。 p>
/ * Subject and To * /
$ to ='nnorman@dimplexthermal.com';
$ subject = $ company。 ''。 $ name;

$ headers =“From：$ email

$to = 'nnorman@dimplexthermal.com';
$subject = $company . ' ' . $name;
/* Gathering Data Variables */
$name = $_POST['name'];
$email = $_POST['email'];
$company = $_POST['company'];
You're not setting $company and $name until after you use them in $subject
Try switching the lines round:
/* Gathering Data Variables */
$name = $_POST['name'];
$email = $_POST['email'];
$company = $_POST['company'];
$to = 'nnorman@dimplexthermal.com';
$subject = $company . ' ' . $name;
