php表单不发送

Question

我正在尝试发送一张表格，它花了我3天的时间来设法构建！我真的很挣钱但学习。无论如何，我已经做了我认为正确但我的形式没有找到我？我希望这是一个简单的解决方案！代码如下，我非常感谢任何帮助：

    <?php
    // define variables and set to empty values
    $addDateErr = $nameErr = $emailErr = $subjectErr = $messageErr = $questionErr = "";
    $addDate = $name = $email = $subject = $message = $WebSearch = $SocialMedia =      $WordOfMouth = $Other ="";

    if ($_SERVER["REQUEST_METHOD"] == "POST")
    {
//Date
   if (empty($_POST["addDate"]))
   {$comment = "";}
   else
   {$comment = test_input($_POST["addDate"]);}

//Name
    if (empty($_POST["name"]))
    {$nameErr = "Name is required";}
    else
    {
    $name = test_input($_POST["name"]);
    if (!preg_match("/^[a-zA-Z ]*$/",$name))
    {
    $nameErr = "Only letters and white space allowed";
    }
    }

//Email
   if (empty($_POST["email"]))
   {$emailErr = "Email is required";}
   else
   {
   $email = test_input($_POST["email"]);
   if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
   {
   $emailErr = "Invalid email format";
   }
   }

//Subject
   if (empty($_POST["subject"]))
   {$comment = "";}
   else
   {$comment = test_input($_POST["subject"]);}

//Message
   if (empty($_POST["message"]))
   {$messageErr = "A message is required";}
   else
   {$comment = test_input($_POST["message"]);}

//Question
    if (isset($_POST['question']))
    {
    $menuVar = $_POST['question'];
    } else {
    $menuVar = "----------";}
}
function test_input($data)
{
     $data = trim($data);
     $data = stripslashes($data);
     $data = htmlspecialchars($data);
     return $data;
}
?>

<form method="post" id="form" action="send.php">

    </div><br />

        <select name="question">

        </select>

    <div>
        <input type="submit" value="Send" id="submit">

</form>


       <script>
    $(document).ready(function() {
    $("#datepicker").datepicker({minDate: 129, maxDate: "+5Y", changeMonth: true,changeYear: true, showButtonPanel: true, dateFormat: 'dd MM yy'});
    });

    $('#form').on('submit', function(){
    return $('#email').val() == $('#emailConfirmation').val();
    });
</script>

<style type="text/css">
    .asterix{color: #bc2021;font-size: 20px;}
    .contact-font, #info-req, #opening-text{font-family: 'Raleway', sans-serif; font-weight: 100; color: #000;}
    .border:focus{border: 2px solid #bc2021;}
    #datepicker:focus{border: 2px solid #bc2021;}
    .error {color: #FF0000;}
    #marketing{border: 1px solid black; width: 150px; height: 22px;}
    #submit{width: 100px; height: 25px; font-size: 15px;}
    #submit:active{background-color: #bc2021;}
</style>

以下是send.php文件内容：

<?php
$addDate = $_POST['addDate'];
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$question = $_POST['question'];

$to = "some@email.com";
$subject = "Help!";

$body = "Please do not reply!";

mail($to,$subject,$body);

echo "Message Sent!<a href='index.html'>Home</a>";

?>
