提交按钮不起作用

Question

我已经尝试了所有我能想到的东西，但由于我对交互式表格并不熟悉，所以我已经走到了尽头。我希望你能帮助我。

这是我的HTML

<div class="form-container">
            <div class="response"></div>
            <form class="forms" action="contact/form-handler.php" method="post">
              <fieldset>
                <ol>
                  <li class="form-row text-input-row">
                    <label>Name</label>
                    <input type="text" name="name" value="" class="text-input required" title="" />
                  </li>
                  <li class="form-row text-input-row">
                    <label>Email</label>
                    <input type="text" name="email" value="" class="text-input required email" title="" />
                  </li>
                  <li class="form-row text-input-row">
                    <label>Subject</label>
                    <input type="text" name="subject" value="" class="text-input required" title="" />
                  </li>
                  <li class="form-row text-area-row">
                    <label>Message</label>
                    <textarea name="message" class="text-area required"></textarea>
                  </li>
                  <li class="form-row hidden-row">
                    <input type="hidden" name="hidden" value="" />
                  </li>
                  <li class="button-row">
                    <input type="submit" value="Submit" name="submit" class="btn-submit light" />
                  </li>
                </ol>
                <input type="hidden" name="v_error" id="v-error" value="Required" />
                <input type="hidden" name="v_email" id="v-email" value="Enter a valid email" />
              </fieldset>
            </form>

          </div>

这是我的php

<?php
$name = $_POST['name'];
$visitor_email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];

$email_from = 'sender@sendermail.com';//<== update the email address
$email_subject = "$subject";
$email_body = "You have received a new message from the user $name.\n".
    "Here is the message:\n $message".

$to = "receiver@receivermail.com";//<== update the email address
$headers = "From: $email_from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";

//Send the email!
mail($to,$email_subject,$email_body,$headers);

// Function to validate against any email injection attempts
function IsInjected($str)
{
  $injections = array('(\n+)',
              '(\r+)',
              '(\t+)',
              '(%0A+)',
              '(%0D+)',
              '(%08+)',
              '(%09+)'
              );
  $inject = join('|', $injections);
  $inject = "/$inject/i";
  if(preg_match($inject,$str))
    {
    return true;
  }
  else
    {
    return false;
  }
}

?>

任何想法导致了什么？
