WordPress非插件版post_view实现文章点击量统计功能

该Wordpress非插件版post_view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。

WordPress非插件版post_view

操作很简单,将下面的文章点击量统计代码添加到你主题的functions.php的最后一个 ?> 的前面

/* 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;
}

然后在需要显示点击数的地方添加下面的调用代码即可

阅读:<?php post_views(' ', ' 次'); ?>

DH还附带提供了下面两个参数,供大家参考

(1)get_most_viewed_format 得到最多阅读的文章,列出5个。

/// 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));
    $output .= "<li>$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)get_totalviews 得到阅读的总数

function get_totalviews($echo = 1) {
  global $wpdb;
  $total_views = $wpdb->get_var("SELECT SUM(meta_value+0) FROM $wpdb->postmeta WHERE meta_key = 'views'");
  if ($echo) echo $total_views;
  else return $total_views;
 }
