WordPress非插件添加文章浏览次数统计功能

WordPress文章浏览次数统计功能是必不可少的，不少主题已经集成该功能，如果你的主题没有集成，你可以使用 WP-Postviews 插件，或者试试本文的代码。 WordPress非插件实现文章浏览次数统计的方法，是DH参考willin kan大师的my_visitor插件来写的，刷新一次文章页面就统计一次，比较简单实用。非插件统计文章浏览次数 1.在主题的 functions.php文件的最后一个 ?> 前面添加下面的代码：

/* 访问计数 */
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：

获取浏览次数最多的文章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：

/// get_most_viewed_format
/// 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));
    $output .= "$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";
   }
  } else {
   $output = "N/An";
  }
  echo $output;
}

然后使用下面的函数调用：
