HTML表单到PHP邮件无法正常工作[重复]

• PHP mail function doesn't complete sending of e-mail 27 answers

I am absolutely bad at PHP programming. I have no experience with it, but I wanted a form on my website with a mail script. So like almost every other person with no experience on a language, I googled up one and customized it.

mail_send.php

<?php 
if(isset($_POST['submit'])){
$to = "[e-mail]"; // I just did this for privacy     
$from = $_POST['email'];     
$name = $_POST['name'];    
$subject = "Form submission";    
$message = $name . " " . $from . " wrote the following:" . "

" . 
$_POST['message'];    

$headers = "From:" . $from;    
mail($to,$subject,$message,$headers);
echo "Mail Sent. Thank you " . $name . ", we will contact you shortly.";
}
?>

and here the HTML code: index.html

 <form role="form" id="feedbackForm" class="text-center" action="mail_send.php" method="post">
          <div class="form-group">
            <label for="name">Naam</label>
            <input type="text" class="form-control" id="name" name="name" placeholder="Name">
            <span class="help-block" style="display: none;">Voer uw naam in..</span></div>
          <div class="form-group">
            <label for="email">E-Mail</label>
            <input type="email" class="form-control" id="email" name="email" placeholder="Email Address">
            <span class="help-block" style="display: none;">Voer een geldig e-mailadres in.</span></div>
          <div class="form-group">
            <label for="message">Bericht</label>
            <textarea rows="10" cols="100" class="form-control" id="message" name="message" placeholder="Message"></textarea>
            <span class="help-block" style="display: none;">Voer een bericht in.</span></div>
          <button type="submit" id="feedbackSubmit" class="btn btn-primary btn-lg" style=" margin-top: 10px;"> Verstuur</button>
        </form>

So I have uploaded both files to my Website Server so I've tested it online, but still without success. Any smart guys being able to help me?

Thanks in advance :)

Please modify button tag

<button type="submit"  name="submit" id="feedbackSubmit" class="btn btn-primary btn-lg" style=" margin-top: 10px;"> Verstuur</button>
