Question

我在为我的网站设置邮件表单时遇到了一些麻烦。目前，当我在表单上按提交时，发送给我的电子邮件只显示它的文本部分，并且它不显示变量！因此，在我的电子邮件中，它只会显示“此消息来自”

我对PHP很新 - 希望有人可以看看，也许指出我没有得到的东西？

谢谢！

<? 
if(isset($_POST['message']) && ($_POST['message'] != '')){
    $name = $_POST["name"];
    $subject = "New Request";

    $recipient = "my@email.com";
    $message = $_POST["message"];

    $mailBody = 'This message is from  $name \n $message;

    mail($recipient, $subject, $mailBody);
}
?>

Answer 1

首先 concat 您传入的string.as的可变名称单引号让php认为它是一个字符串。

尝试以下代码：

<? 
if(isset($_POST['message']) && ($_POST['message'] != '')){
    $name = $_POST["name"];
    $subject = "New Request";

    $recipient = "my@email.com";
    $message = $_POST["message"];

    $mailBody = 'This message is from  '.$name."\r\n". $message;


    mail($recipient, $subject, $mailBody);
}
?>

另外要了解单引号和双引号的区别，您可以参考以下链接：

Answer 2

你应该使用double quoted string 另请查看this

<? 
if(isset($_POST['message']) && ($_POST['message'] != '')){
    $name = $_POST["name"];
    $subject = "New Request";

    $recipient = "my@email.com";
    $message = $_POST["message"];

    $mailBody = 'This message is from  '.$name."\r\n". $message;

    mail($recipient, $subject, $mailBody);
}
?>

Answer 3

$mailBody = 'This message is from  '.$name.' \r\n'. $message;

OR

$mailBody = "This message is from $name\r\n$message";

您编写变量的第一行是在单引号内，它将您的变量作为文本，其中没有引号或双引号内部可以将这些作为变量。
