        $email=$_POST['email'];
    //  $subject=$_POST['subject'];
        $msg=$_POST['msg'];

       $to='contact@****.my';

      .$subject."\n". "Wrote the following: "."\n\n".$msg;

if（isset（$\u POST['submit']））{
$name=$_POST['name']；
$email=$_POST['email']；
//$subject=$_POST['subject']；
$msg=$_POST['msg']；
}
$to='contact@****.my'；
$subject='Contact Form'；
$message=“Name:”.$Name.\n.“电子邮件：”.$email.\n.“主题：”
.$subject.“\n”。写了以下内容：“.\n\n”。$msg；
$headers=“From:”.$email；
if（邮件（$to、$subject、$message、$headers））{
echo“您的邮件已发送。谢谢！”“$name.”，我们将
尽快与您联系”；
}
否则{
echo“出了问题！”；
} 

您忘记关闭表单，并且没有给提交按钮命名，因此php无法工作

<form action="contact-form-handler.php" method="post" 
    class="contactForm">
          <div class="row">
            <div class="span4 form-group field">
              <input type="text" name="name" placeholder="Your Name" data- 
                rule="minlen:4" data-msg="Please enter at least 4 chars" />
              <div class="validation"></div>
            </div>

            <div class="span4 form-group">
              <input type="email" name="email" placeholder="Your Email" 
                data-rule="email" data-msg="Please enter a valid email" />
              <div class="validation"></div>
            </div>

            <div class="span8 form-group">
           <textarea name="message" rows="5" data-rule="required" data- 
           msg="Please write something for us" placeholder="Message"> 
           </textarea>
              <div class="validation"></div>
              <div class="text-center">
                <button class="btn btn-success" type="submit" name="submit"
             value="sendmessage">Send message</button>
</form>

到

一定是

$msg=$_POST['message'];

及

一定是

$subject."\n". "Wrote the following: "."\n\n".$msg;

您的按钮没有名称，您从未关闭formI已关闭表单（），我已更改了您提到的内容，但在我单击“提交”后未显示成功消息。不，我没有收到任何错误，单击“提交”时没有响应

$message="Name: " .$name."\n"."email: " .$email."\n"."Subject: " ;

$msg=$_POST['msg']; 

$msg=$_POST['message'];

.$subject."\n". "Wrote the following: "."\n\n".$msg;

$subject."\n". "Wrote the following: "."\n\n".$msg;
