用于从发送电子邮件的网站发送电子邮件的 PHP 代码，但并非所有用户输入都按预期进行

Question

我有 php 代码打算从我的网站发送电子邮件。但是，我从我的网站收到的电子邮件不完整{“电话、主题等丢失”}。我只能看到发件人电子邮件和他们发送的消息。我试图解决这个问题，因为我是 php 新手，我无法弄清楚是什么导致了这个问题。$product = $_POST["product"];$name = $_POST["name"];$email= $_POST["email"];$phone= $_POST["phone"];$subject= $_POST["subject"];$message= $_POST["message"];$emailSubject="Emaill Subject" .$subject;$txt = "You have recived Inquiry from:$name.\n".        "Product: $product.\n".        "Product: $product.\n".        "Phone: $phone".        "Message: $message.\n";$to = '[e-mail]'; $headers = "Mail From: $email \r\n" ;  // Sender's E-mail         mail($to, $subject, $txt, $headers);if (@mail($to, $subject, $txt, $headers)){    echo 'The message has been sent.';}else{    echo 'failed';}电子邮件：[e-mail] 电话：文本：测试联系表这是我收到的电子邮件。

尝试这个

$product = $_POST["product"];

$name = $_POST["name"];

$email= $_POST["email"];

$phone= $_POST["phone"];

$subject= $_POST["subject"];

$message= $_POST["message"];

$emailSubject="Emaill Subject" .$subject;

$txt = "You have recived Inquiry from:$name.\n".

        "Product: $product.\n".

        "Product: $product.\n".

        "Phone: $phone".

        "Message: $message.\n";

$to = '[e-mail]'; 

$headers = "From: $email \r\n" ;  // Sender's E-mail         

mail($to, $subject, $txt, $headers);

if (@mail($to, $subject, $txt, $headers))

{

    echo 'The message has been sent.';

}else{

    echo 'failed';

}

我将邮件发件人：更改为发件人：
