制作酷炫的CSS3读者墙

读者墙可以很直观地看到最近网站访客的活跃度，我们可以为网站做一个酷炫的CSS3读者墙，样式来自大前端，代码来自折子戏。

一、创建readerwall页面

1.复制主题目录下的page.php文件，改名为readerwall.php，打开文件后在顶部添加代码:

<?php
/*
Template Name: Reader wall
*/
?>

2.在readerwall.php中搜索<?php the_content(); ?> ,在此句的前面添加以下代码：

<!-- start 读者墙  Edited By iSayme-->
<?php
 
    $query="SELECT COUNT(comment_ID) AS cnt, comment_author, comment_author_url, comment_author_email FROM (SELECT * FROM $wpdb->comments LEFT OUTER JOIN $wpdb->posts ON ($wpdb->posts.ID=$wpdb->comments.comment_post_ID) WHERE comment_date > date_sub( NOW(), INTERVAL 24 MONTH ) AND user_id='0' AND comment_author_email != '改成你的邮箱账号' AND post_password='' AND comment_approved='1' AND comment_type='') AS tempcmt GROUP BY comment_author_email ORDER BY cnt DESC LIMIT 39";//大家把管理员的邮箱改成你的,最后的这个39是选取多少个头像，大家可以按照自己的主题进行修改,来适合主题宽度
 
    $wall = $wpdb->get_results($query);
 
    $maxNum = $wall[0]->cnt;
 
    foreach ($wall as $comment)
 
    {
 
        $width = round(40 / ($maxNum / $comment->cnt),2);//此处是对应的血条的宽度
 
        if( $comment->comment_author_url )
 
        $url = $comment->comment_author_url;
 
        else $url="#";
  $avatar = get_avatar( $comment->comment_author_email, $size = '36', $default = get_bloginfo('wpurl').'/avatar/default.jpg' );
 
        $tmp = "<li><a target="_blank" href="".$comment->comment_author_url."">".$avatar."<em>".$comment->comment_author."</em> <strong>+".$comment->cnt."</strong></br>".$comment->comment_author_url."</a></li>";
 
        $output .= $tmp;
 
     }
 
    $output = "<ul class="readers-list">".$output."</ul>";
 
    echo $output ;
 
?>
 
<!-- end 读者墙 -->

二、在Style.css文件中添加如下代码：

.readers-list{line-height:18px;text-align:left;overflow:hidden;_zoom:1}
.readers-list li{width:200px;float:left;*margin-right:-1px}
.readers-list a,.readers-list a:hover strong{background-color:#f2f2f2;background-image:-webkit-linear-gradient(#f8f8f8,#f2f2f2);background-image:-moz-linear-gradient(#f8f8f8,#f2f2f2);background-image:linear-gradient(#f8f8f8,#f2f2f2)}
.readers-list a{position:relative;display:block;height:36px;margin:4px;padding:4px 4px 4px 44px;color:#999;overflow:hidden;border:#ccc 1px solid;border-radius:2px;box-shadow:#eee 0 0 2px}
.readers-list img,.readers-list em,.readers-list strong{-webkit-transition:all .2s ease-out;-moz-transition:all .2s ease-out;transition:all .2s ease-out}
.readers-list img{width:36px;height:36px;float:left;margin:0 8px 0 -40px;border-radius:2px}
.readers-list em{color:#666;font-style:normal;margin-right:10px}
.readers-list strong{color:#ddd;width:40px;text-align:right;position:absolute;right:6px;top:4px;font:bold 14px/16px microsoft yahei}
.readers-list a:hover{border-color:#bbb;box-shadow:#ccc 0 0 2px;background-color:#fff;background-image:none}
.readers-list a:hover img{opacity:.6;margin-left:0}
.readers-list a:hover em{color:#EE8B17;font:bold 12px/36px microsoft yahei}
.readers-list a:hover strong{color:#EE8B17;right:150px;top:0;text-align:center;border-right:#ccc 1px solid;height:44px;line-height:40px}

三、于后台创建一个新的页面，页面模板选择“Reader wall”，内容任意，发布。

查看你刚刚创建的读者墙页面，是不是很帅？
