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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

/* 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：

1	阅读： post_views(' ', ' 次'); ?>

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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

/// 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/A n"; } echo $output; }

然后使用下面的函数调用：

1	get_most_viewed_format(); ?>
