Parsley表格未提交

我创建了一个表单，该表单使用Parsley.js进行验证，然后使用php提交。表单验证得很好，但没有提交到php页面：form_submission.php

演示表格可以在这里找到http://tanujd.com/demop/contact-form.html（我已经预先弹出了带有伪内容的表格，使其更容易测试）

使用的HTML是：

<form action="form_submission.php" id="contactform" method="post" data-validate="parsley">
<table width="200" border="0" cellspacing="0" cellpadding="0">
  <tr class="name">
    <td>
        <label for="firstname">First Name*:</label>
        <input type="text" id="firstname" name="firstname" data-trigger="change" required data-required="true" value="dummyfname" />
    </td>
    <td style="margin-left:10px;">
        <label for="lastname">Last Name*:</label>
        <input type="text" id="lastname" name="lastname" data-trigger="change" required data-required="true" value="dummylname" />
    </td>
  </tr>
  <tr>
    <td>
        <label for="mobile">Mobile*</label>
        <input type="text" id="mobile" name="mobile" data-type="phone" data-trigger="change" required data-required="true" value="+1123456789" />
    </td>
  </tr>
  <tr>
    <td>
        <label for="email">Email* :</label>
        <input type="text" id="email" name="email" data-type="email" data-trigger="change" required data-required="true" value="dummy@emailid.com" />
    </td>
  </tr>
  <tr>
    <td>
        <label for="subject">Whats this about*:</label>
        <select id="subject" name="subject" required="required" data-required="true">
            <option value="1" selected="selected">Yey</option>
            <option value="2">Yey1</option>
            <option value="3">Yey2</option>
        </select>
    </td>
  </tr>
  <tr>
  <tr>
    <td>
        <label for="category">Subject:</label>
        <input type="text" id="category" name="category" value="Dummy Subject" />
    </td>
  </tr>
  <tr>
    <td>
        <label for="message">Tell us about it*</label>
        <textarea id="message" name="message" data-trigger="change" required data-required="true">Dummy Text</textarea>
    </td>
  </tr>
  <tr>
    <td>
        <input type="hidden" id="formid" name="formid" value="contactusform" />
        <input class="button" name="submit" type="button" value="submit" onClick="javascript:$('#contactform').parsley( 'validate' );" />
    </td>
  </tr>
</table>
</form>

页面中的PHP代码：form_submission.PHP（在线文件显然有我的正确电子邮件地址）

<?php
$formid = $_POST['formid'];
$email_to = "myemailaddress@goeshere.com";
$first_name = $_POST['firstname']; // required
$last_name = $_POST['lastname']; // required
$mobilenum = $_POST['mobile'];
$email_from = $_POST['email']; // required
$email_subject = "Website Contact Form Submission: ". $_POST['subject'];
$subject = $_POST['subject'];
//$categoryselect = $_POST('category').value();
$message = $_POST['message']; // required
echo($email_from);
$email_message = "Submission details below.'n'n";
$email_message .= "First Name: ".clean_string($first_name)."'n";
$email_message .= "Last Name: ".clean_string($last_name)."'n";
$email_message .= "Mobile: ".clean_string($telephone)."'n";
$email_message .= "Email: ".clean_string($email_from)."'n";
$email_message .= "Whats this about: ".clean_string($subject)."'n";
$email_message .= "Category: ".clean_string($category)."'n";
$email_message .= "Comments: ".clean_string($comments)."'n";
$email_message = wordwrap($email_message, 70, "'r'n");
$headers = 'From: '.$email_from."'r'n".
            'Reply-To: '.$email_from."'r'n" .
            'X-Mailer: PHP/' . phpversion();
mail($email_to, $email_subject, $email_message,$headers) or die("Error!");
echo "Thank you for contacting us. We will be in touch with you very soon. 'r'n";
?>

该页面验证良好，但它不会转到PHP页面并提交表单。如果我按原样加载php页面，它会给我发一条空白消息（所以基本上php表单提交者正在工作）

知道我该怎么解决这个问题吗？
