wordpress实现读者墙的方法

青衣

本文实例讲述了wordpress实现读者墙的方法。分享给大家供大家参考。具体实现方法如下：
1.复制PAGE.php页面,改名为readerwall.php,然后在其顶部添加如下代码:

代码如下:

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

提示:你可以先修改部分代码再运行。
2.在需要添加读者墙的位置添加以下代码:

代码如下:

<!-- 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,代码如下:

代码如下:

<?php  
$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 -->

提示:你可以先修改部分代码再运行。
3.在主题目录中style.css添加以下样式:

代码如下:

.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}
