php电子邮件表单问题 [英] php email form issue

问题描述

我无法设置PHP表单。这是我第一次尝试这样做。我有表单提交并发送到我的电子邮件。但是我收到2封电子邮件。

I am having trouble setting up a PHP form. Its my first try at doing this. I have got the form to submit and send to my email. But i receive 2 emails.

是否说（未知的发件人）????

Is it ment to say (unknown sender) ???? surely not.

，并在此图片中显示，只有一个表单提交。它发送一个空白的电子邮件，一个与文本。但只有消息。有什么问题？

$message = $_POST['message'];
$to = "[e-mail]";
$subject = "New Message";

mail ($to, $subject, $message, "From: " . $name);
echo "Your Message has been sent";

?>

推荐答案

From 标题应该是一个电子邮件地址，或者是一个名称和电子邮件地址，格式如下：

The From header should be an email address or both a name and email address in the format:

From: John Smith <[e-mail]>

它不应该只是一个名字，这是你似乎在做什么。还要记住使用 \r\\\
终止标题。

It should never be just a name, which is what you appear to be doing. Also remember to terminate headers with \r\n.

使用用户输入作为从标题通常不是一个好主意，因为它可能会引入标题注入漏洞，并且还会导致垃圾邮件过滤器结果不一致。对于联系表单，我建议您使用自己的静态电子邮件地址。

Using user input as the From header is not usually a good idea because it can introduce a header injection vulnerability, and it can also cause inconsistent spam filter results. For a contact form, I suggest just using a static email address of your own.
