WordPress Theme Development 7 - Comments

There is an enhancement for comment display in WordPress 2.7. New template tags are introduced. This WordPress theme will be using those enchancement too. In the header file, header.php, code as following is added right before the call to wp_head(); for supporting new JavaScrip functionality with comment threading in WordPress 2.7.

57-header.php (Source)

<?php if ( is_singular() ) wp_enqueue_script( 'comment-reply' );
  // enables nested comments in WP 2.7 ?>

Nows, let's concerntrate on comments file, comments.php, itself. Due to this theme support at least WordPress version 2.7, it won't include any legacy code that support WordPress version less then 2.7. I used Migrating Plugins and Themes to 2.7/Enhanced Comment Display as reference. Great reference. We won't repeat on what they already said. An example of comments file, comments.php that supporting WordPress 2.7 comments enhancement as following.

57-comments.php (Source)

 * @package WordPress
 * @subpackage Your_Theme
<!-- Comments for WP 2.7 and more -->
if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' ==
    die (__('Please do not load this page directly. Thanks!'));
if ( post_password_required() ) : ?>
    <p><?php _e('This post is password protected. Enter the password to view
      comments.'); ?></p>
<?php return; endif; // END: if ( post_password_required() ) ?>

    <?php comments_number(__('No Comments'), __('1 Comment'),
      __('% Comments')); ?>

<?php if ( have_comments() ) : // Showing all the comments ?>
        <?php wp_list_comments(); ?>
    <?php previous_comments_link(); ?>
    <?php next_comments_link(); ?>
<?php else : // this is displayed if there are no comments so far ?>
    <p><?php _e('No comments yet.'); ?></p>
<?php endif; // END: if ( $comments ) ?>

<?php if ( comments_open() ) : ?>
<div id="respond">
    <h3><?php comment_form_title( 'Leave a Reply', 'Leave a Reply to %s' ); ?>
    <div id="cancel-comment-reply">
        <small><?php cancel_comment_reply_link() ?></small>

    <?php if ( get_option('comment_registration') && !$user_ID ) :
        // If registration required ?>
        <p><?php printf(__('You must be <a href="%s">logged in</a>
          to post a comment.'),
    <?php else : // If registration do not required ?>

    <form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php"
      method="post" id="commentform">

        <?php if ( $user_ID ) : // Log in user info ?>

            <p><?php printf(__('Logged in as %s.'),
            '<a href="'.get_option('siteurl').'/wp-admin/profile.php">'
            .$user_identity.'</a>'); ?>
            <a href="<?php echo wp_logout_url(get_permalink()); ?>"
              title="<?php _e('Log out of this account'); ?>">
              <?php _e('Log out &raquo;'); ?></a></p>

        <?php else : // Public user ?>

            <p><input type="text" name="author" id="author" value="
              <?php echo $comment_author; ?>" size="22" tabindex="1" />
            <label for="author"><small><?php _e('Name'); ?>
              <?php if ($req) _e('(required)'); ?></small></label></p>

            <p><input type="text" name="email" id="email"
              value="<?php echo $comment_author_email; ?>" size="22"
              tabindex="2" />
            <label for="email"><small>
              <?php _e('Mail (will not be published)');?>

        <?php endif; ?>

          <?php printf(__('You can use these tags: %s'), allowed_tags()); ?>
        <p><textarea name="comment" id="comment" cols="100%" rows="10"
        <p><input name="submit" type="submit" id="submit" tabindex="5"
          value="<?php echo attribute_escape(__('Submit Comment')); ?>" /></p>
        <?php comment_id_fields(); ?>
        <?php do_action('comment_form', $post->ID); ?>

    <?php endif; // END: if ( get_option('comment_registration') && !$user_ID )
    // If registration required and not logged in ?>

<?php else : // Comments are closed ?>
    <p><?php _e('Sorry, the comment form is closed at this time.'); ?></p>
<?php endif; // END: if ( comments_open() )?>

Currently there is no plan on developing popup comments template. Therefore, there will be no popup comments file, comments-popup.php, in this theme. However, if you want to publish your theme publicly, you might want to consider for adding it.
