WordPress为最近浏览最多（热门）文章添加缩略图 – WordPress 教程

之前配合wp-postviews插件，通过添加：

###Get TimeSpan Most Viewedfunction get_timespan_most_viewed($mode = '', $limit = 10, $days = 7, $display = true) {      global $wpdb, $post;          $limit_date = current_time('timestamp') - ($days*86400);       $limit_date = date("Y-m-d H:i:s",$limit_date);        $where = '';      $temp = '';      if(!empty($mode) && $mode != 'both') {          $where = "post_type = '$mode'";      } else {          $where = '1=1';      }      $most_viewed = $wpdb->get_results("SELECT $wpdb->posts.*, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE post_date < '".current_time('mysql')."' AND post_date > '".$limit_date."' AND $where AND post_status = 'publish' AND meta_key = 'views' AND post_password = '' ORDER  BY views DESC LIMIT $limit");      if($most_viewed) {          foreach ($most_viewed as $post) {              $post_title = get_the_title();              $post_views = intval($post->views);              $post_views = number_format($post_views);              $temp .= "<li><a href="".get_permalink()."">$post_title</a>".__('', 'wp-postviews')."</li>";          }      } else {          $temp = '<li>'.__('N/A', 'wp-postviews').'</li>'."n";      }      if($display) {          echo $temp;      } else {          return $temp;      }  }  

调用显示某时间段内浏览最多日志的功能。

近日，有童鞋问这些浏览最多的文章可不可以加上缩略图，简单修改了一下上述代码：

//按时间获得最受欢迎文章（带缩略图）function get_timespan_most_viewed($mode = '', $limit = 10, $days = 7, $display = true) {      global $wpdb, $post;          $limit_date = current_time('timestamp') - ($days*86400);       $limit_date = date("Y-m-d H:i:s",$limit_date);        $where = '';      $temp = '';      if(!empty($mode) && $mode != 'both') {          $where = "post_type = '$mode'";      } else {          $where = '1=1';      }      $most_viewed = $wpdb->get_results("SELECT $wpdb->posts.*, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE post_date < '".current_time('mysql')."' AND post_date > '".$limit_date."' AND $where AND post_status = 'publish' AND meta_key = 'views' AND post_password = '' ORDER  BY views DESC LIMIT $limit");      if($most_viewed) {          foreach ($most_viewed as $post) {              $post_title = get_the_title();              $post_views = intval($post->views);              $post_views = number_format($post_views);              $thumb =  "<img src="".get_post_meta(get_the_id(), 'thumbnail', true)."">";              $temp .= "<li><a href="".get_permalink()."">$post_title,$thumb</a>".__('', 'wp-postviews')."</li>";          }      } else {          $temp = '<li>'.__('N/A', 'wp-postviews').'</li>'."n";      }      if($display) {          echo $temp;      } else {          return $temp;      }  }  

其中：

get_post_meta(get_the_id(), 'thumbnail', true)

显示添加自定义栏目：thumbnail　文章的缩略图，也可以修改为调用特色图像：

the_post_thumbnail('post_thumbnail');

调用方法，在主题模板适当位置添加：

<ul>      <?php if (function_exists('get_most_viewed')): ?>       <?php get_timespan_most_viewed('post',8,60, true, true); ?>       <?php endif; ?>  </ul>  

以上方法仅供参考。
