WordPress获取文章浏览次数及获取浏览次数最多的文章

纯代码统计文章浏览次数
1、在主题的 functions.php文件的最后一个 ?> 前面添加下面的代码：

function record_visitors(){   
  if (is_singular()){   
      global $post;   
      $post_ID = $post->ID;   
      if($post_ID){   
         $post_views = (int)get_post_meta($post_ID, 'views', true);   
         if(!update_post_meta($post_ID, 'views', ($post_views+1))) {   
            add_post_meta($post_ID, 'views', 1, true);   
         }   
      }   
    }   
}   
add_action('wp_head', 'record_visitors');   
//函数名称：post_views   
//函数作用：取得文章的阅读次数   
function post_views($before = '(点击 ', $after = ' 次)', $echo = 1) {   
  global $post;   
  $post_ID = $post->ID;   
  $views = (int)get_post_meta($post_ID, 'views', true);   
  if ($echo) echo $before, number_format($views), $after;   
  else return $views;   
}  

2、在需要显示该统计次数的地方使用下面的代码调用：

<?php post_views(' ', ' 次'); ?>

获取浏览次数最多的文章
1、这个一般来说,就是用来获得热门文章了.如果要获取上面的函数统计出来的浏览次数最多的文章，可以在 functions.php文件的最后一个 ?>; 前面添加下面的代码：

//函数作用：取得阅读最多的文章   
function get_most_viewed_format($mode = '', $limit = 10, $show_date = 0, $term_id = 0, $beforetitle= '(', $aftertitle = ')', $beforedate= '(', $afterdate = ')', $beforecount= '(', $aftercount = ')') {   
  global $wpdb, $post;   
  $output = '';   
  $mode = ($mode == '') ? 'post' : $mode;   
  $type_sql = ($mode != 'both') ? "AND post_type='$mode'" : '';   
  $term_sql = (is_array($term_id)) ? "AND $wpdb->term_taxonomy.term_id IN (" . join(',', $term_id) . ')' : ($term_id != 0 ? "AND   $wpdb->term_taxonomy.term_id = $term_id" : '');   
  $term_sql.= $term_id ? " AND $wpdb->term_taxonomy.taxonomy != 'link_category'" : '';   
  $inr_join = $term_id ? "INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)" : '';   
  // database query   
  $most_viewed = $wpdb->get_results("SELECT ID, post_date, post_title, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON ($wpdb->posts.ID = $wpdb->postmeta.post_id) $inr_join WHERE post_status = 'publish' AND post_password = '' $term_sql $type_sql AND meta_key = 'views' GROUP BY ID ORDER BY views DESC LIMIT $limit");   
  if ($most_viewed) {   
   foreach ($most_viewed as $viewed) {   
    $post_ID    = $viewed->ID;   
    $post_views = number_format($viewed->views);   
    $post_title = esc_attr($viewed->post_title);   
    $get_permalink = esc_attr(get_permalink($post_ID));   
    $output .= "<li>$beforetitle$post_title$aftertitle";   
    if ($show_date) {   
      $posted = date(get_option('date_format'), strtotime($viewed->post_date));   
      $output .= "$beforedate $posted $afterdate";   
    }   
    $output .= "$beforecount $post_views $aftercount</li>";   
   }   
  } else {   
   $output = "<li>N/A</li>n";   
  }   
  echo $output;   
} 

2、然后使用下面的函数调用：

<?php get_most_viewed_format(); ?>
