WordPress的强大毋庸置疑,可它的强大却让许多博客的速度像乌龟一般。。。WP拥有2万多个插件的支持,在一个博客中若安装了多个插件会使页面的加载速度变慢许多。所以能用代码的地方尽量要使用代码。
这次WP酷给大家提供的是最常用的WP-Postviews插件的代码版,出自倡萌。
1、基本使用方法
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 ?> 的前面即可:
/* 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 $views; }
然后在需要显示点击数的地方添加下面的调用代码即可:
阅读:<?php post_views(' ', ' 次'); ?>
2、函数拓展
不想折腾的同学看完第一点就可以结束了。这里倡萌还给出了两个函数供大家使用:
get_most_viewed_format 得到最多阅读的文章,列出5个:
/// get_most_viewed_format /// 函数作用:取得阅读最多的文章 function get_most_viewed_format($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; }
写这类文章,应该在最开始截图一张代码加入后的效果。这样更清晰
