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:
- 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($post_ID, 'views', 1, true);
- }
- }
- function post_views($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 $views;
- }
2. 在需要显示该统计次数的地方使用下面的代码调用:
- 阅读:<?php post_views(' ', ' 次'); ?>
获取浏览次数最多的文章
如果要获取上面的函数统计出来的浏览次数最多的文章,可以在 functions.php 文件的最后一个 ?> 前面添加下面的代码:
- function get_most_viewed_format($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)" : '';
- $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;
- }
然后使用下面的函数调用:
- <?php get_most_viewed_format(); ?>
