i have used following source code to add extra CITY field to wordpress comment form

<?php

/* Plugin Name: Comment meta data test Version: 1.0 Plugin URI: http://wpengineer.com Description: Comment meta data test Author: Latz Author URI: http://wpengineer.com */

add_filter( 'comment_form_defaults', 'change_comment_form_defaults');

function change_comment_form_defaults($default) {

$commenter = wp_get_current_commenter();    

    $default['fields']['email'] .= '<p class="comment-form-author">' .
                    '<label for="city">'. __('CITY') . '</label>
    
            <input id="city" name="city" size="30" type="text" /></p>';

return $default;

}

add_filter( 'preprocess_comment', 'verify_comment_meta_data' ); function verify_comment_meta_data($commentdata) { if ( ! isset( $_POST['city'] ) ) wp_die( __('Error: please fill the required field (city).') ); return $commentdata; }

add_action( 'comment_post', 'save_comment_meta_data' ); function save_comment_meta_data( $comment_id ) { add_comment_meta( $comment_id, 'city', $_POST['city'] ); }

add_filter( 'get_comment_author_link', 'attach_city_to_author' ); function attach_city_to_author( $author ) { $city = get_comment_meta( get_comment_ID(), 'city', true ); if ( $city ) $author .= " $city "; return $author; }

?>

This shows the extra field and wordpress comment form and its output is displayed alogn with wordpress comment author name I want to Display only city name without author name how to do this?
