如何实现WordPress读者墙按评论等级显示相应读者？
我们国内很多 WordPress 主题都会带有一个读者墙功能，Nana 主题也不一例外，但是看多了按总评论数的排行榜，是否有点腻歪？而且我们大多数主题都有评论等级的功能，是否想过读者按评论等级逐级显示出来？今天就教大家如何实现 WordPress 读者墙按评论等级显示相应读者。大概的效果图如下：
1、制作评论榜单模板。以 Nana 主题为例，找到 template-readers 文件，复制一份并重名为 template-pinglunbang，然后打开该文件，找到以下代码
Template Name: 读者百强榜
修改为
Template Name: 评论榜单
继续找到以下代码
- <?php
- function readers_wall($limit = “100”)
- {
- global $wpdb;
- $counts = $wpdb->get_results(“SELECT count(comment_author) AS cnt, comment_author, comment_author_url, comment_author_email FROM $wpdb->comments WHERE user_id!=’1′ AND comment_author!=’1′ AND comment_approved=’1′ AND comment_type=” GROUP BY comment_author ORDER BY cnt DESC LIMIT $limit”);
- $i = 0;
- $type=”;
- foreach ($counts as $count ) {
- $i++;
- $c_url = $count->comment_author_url;
- if (!$c_url) {
- $c_url = “https://boke112.com”;
- }
- $tt = $i;
- if ($i == 1) {
- $tt = “读者之青龙”;
- }
- else if ($i == 2) {
- $tt = “读者之白虎”;
- }
- else if ($i == 3) {
- $tt = “读者之朱雀”;
- }
- else if ($i == 4) {
- $tt = “读者之玄武”;
- }
- else {
- $tt = “第” . $i . “名”;
- }
- $avatar = my_avatar( $count->comment_author_email,36,$default=”,$count->comment_author);
- if ($i < 5) {
- $type .= “<a . $i . “” target=”_blank” href=”” . $c_url . “” title=”【” . $tt . “】评论：” . $count->cnt . “”><h4>【” . $tt . “】</h4>”.$avatar.“<strong>” . $count->comment_author . “</strong>” . $c_url . “</a>”;
- }
- else {
- $type .= “<a target=”_blank” href=”” . $c_url . “” title=”【” . $tt . “】评论：” . $count->cnt . “”>” . $avatar . $count->comment_author . “</a>”;
- }
- }
- echo $type;
- }
- ?>
- <div class=“readers”>
- <?php readers_wall(100);?>
- >
</div
修改为

</div
保存并更新文件。
PS：以上代码中的评论的等级名称及相对应的评论数量请自行修改即可。</div
2、新建评论榜单页面。后台新建一个页面，模板就选我们刚才新创建的“评论榜单”然后直接修好好固定链接之后直接发布即可。
