Comment Form Development Issue

I resolved the case. Problem here was on &fields variable declaration and also to ‘comment_field’ assignment. I had to change name fields with the correct ones.

Check code below:

function dck_custom_comment_form() {
   //Declare Vars
   $comment_author="Name *";
   $comment_email="Email *";
   $comment_body = 'Comment *';
   $comment_cookies_1 = ' By commenting you accept the';
   $comment_cookies_2 = ' Privacy Policy';
   $commenter = wp_get_current_commenter();

$fields = array(
    //Author field
    'author' => '<div class="row"><div class="col-md-6"><div class="form-group"><input name="author" id="name" placeholder="' . $comment_author .'" class="form-control" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '"></div></div>',
    //Email Field
    'email' => '<div class="col-md-6"><div class="form-group"><input name="email" id="email" placeholder="' . $comment_email .'" class="form-control" type="email" value="' . esc_attr(  $commenter['comment_author_email'] ) . '"></div></div></div>',
    //Cookies
    'cookies' => '<div class="col-md-12"><div class="form-group"><input type="checkbox" required>' . $comment_cookies_1 . '<a href="' . get_privacy_policy_url() . '">' . $comment_cookies_2 . '</a></div></div>',
);

//Array
$comments_args = array(
    'fields' => $fields,
    'comment_field' => '<div class="row"><div class="col-md-12"><div class="form-group"><textarea name="comment" id="message" placeholder="' . $comment_body .'" rows="4" aria-required="true" class="form-control"></textarea></div></div></div>',
    'comment_notes_after' => '',
    'title_reply' => 'Please Post Your Comments & Reviews',
    'label_submit' => 'Post Comment'
);
comment_form( $comments_args );
  }

Thanks for your effort!
