rin-wendy.com情侣模板的制作思路(二)

由 admin 发表于 2009/03/09 ┊7,292 PV

上一篇分析的是情侣模板的基本布局，接下来就是评论部分。主要是判断非作者、作者A和作者B，还有奇偶的问题。

1. 修改comments.php，在wp_list_comments代码那加上&callback=my_comment。

1	<?php wp_list_comments('type=comment&callback=my_comment'); ?>

2. 修改function.php，加入如下代码

function my_comment($comment, $args, $depth) {
$GLOBALS['comment'] = $comment; ?>
<li <?php love_class(); ?> id="li-comment-<?php comment_ID() ?>">
<div id="comment-<?php comment_ID(); ?>">
<div class="comment-text">
<div class="comment-text-top"> </div>
<?php comment_text() ?>

<?php if ($comment->comment_approved == '0') : ?>
<em><?php _e('Your comment is awaiting moderation.') ?></em>
<?php endif; ?>

<?php edit_comment_link(__('(Edit)'),' ','') ?>
<div class="comment-text-bot"> </div>
</div>

<div class="comment-author vcard">
<?php echo get_avatar($comment,$size='48',$default='<path_to_url>' ); ?>
<?php printf(__('<cite class="fn">%s</cite> <span class="says">says:</span>'), get_comment_author_link()) ?>
</div>

<div class="comment-meta commentmetadata">
<?php printf(__('%1$s at %2$s'), get_comment_date(), get_comment_time()) ?>
</div>
</div>
}

3. function.php，加入如下代码
