I was facing same problem and was searching for solution i found the solution

Open your function.php file and past below code:

    function comment_validation_init() {
    if(is_single() && comments_open() ) { ?>        
    <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>
    <script type="text/javascript">
    jQuery(document).ready(function($) {

    rules: {
      author: {
        required: true,
        minlength: 2

      email: {
        required: true,
        email: true

      comment: {
        required: true,
        minlength: 20

    messages: {
      author: "Please fill the required field",
      email: "Please enter a valid email address.",
      comment: "Please fill the required field"

    errorElement: "div",
    errorPlacement: function(error, element) {

    add_action('wp_footer', 'comment_validation_init');

For giving style:

.error  { padding: 10px 0 20px 0; color: #FF0000; }
input.error, textarea.error { color:#000000; }

    Please add an explanation. What does your code exactly? And never use the wrong jQuery version, always enqueue the built-in jQuery.

  • It's important to point out that you're using the validate plugin here
