  This code is for adding additional checkbox preferences (News and notification) to user’s metadata in profile page. The code is written based on dquinn.net’s excellent tutorial. If you need to know how to do radio buttons, textarea, dropdown … etc, definitely check out the tutorial @

  /* Adding custom user profile meta data in Wordpress */
  /* You can add this to an existing plugin or create your own plugin */
  
  class custom_user_meta {
  
    function custom_user_meta() {
  
      add_action('show_user_profile', array(&$this,'action_show_user_profile'));
      add_action('edit_user_profile', array(&$this,'action_show_user_profile'));
      add_action('personal_options_update', array(&$this,'action_process_option_update'));
      add_action('edit_user_profile_update', array(&$this,'action_process_option_update'));
  
    }
  
    function action_show_user_profile() {
      global $user_id;
      ?>
      <h3><?php _e('E-mail'); ?></h3>
  
      <table class="form-table">
  
        <tr>
          <th><?php _e('Latest News'); ?></th>
