WordPress免插件实现文章阅读次数 – WordPress 教程

一般为WordPress文章添加阅读次数统计，会用到wp-postviews或者wp-postviews-plus插件，这里分享两段不用插件实现Wordpress文章阅读次数的代码，供大家参考。

代码一：

一、首先将下面代码加到主题functions模版文件中：

function getPostViews($postID){       $count_key = 'post_views_count';       $count = get_post_meta($postID, $count_key, true);       if($count==''){           delete_post_meta($postID, $count_key);           add_post_meta($postID, $count_key, '0');           return "0 View";       }       return $count.' Views';   }   function setPostViews($postID) {       $count_key = 'post_views_count';       $count = get_post_meta($postID, $count_key, true);       if($count==''){           $count = 0;           delete_post_meta($postID, $count_key);           add_post_meta($postID, $count_key, '0');       }else{           $count++;           update_post_meta($postID, $count_key, $count);       }   }  

二、接下来将下面代码加到主题single模版主循环的中：

<?php setPostViews(get_the_ID()); ?>  

也就是类似这句的下面

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>  

三、最后，将调用显示阅读次数代码加到single模版适当的位置：

<?php echo getPostViews(get_the_ID()); ?>  

如果想在其它位置显示阅读次数，可以将下面代码也加到functions模版中：

remove_action（'wp_head'，'adjacent_posts_rel_link_wp_head'，10，0）;  

代码二：

一、同样将下面代码加到主题functions模版文件中：

//postviews   function get_post_views ($post_id) {       $count_key = 'views';       $count = get_post_meta($post_id, $count_key, true);       if ($count == '') {           delete_post_meta($post_id, $count_key);           add_post_meta($post_id, $count_key, '0');           $count = '0';       }       echo number_format_i18n($count);   }   function set_post_views () {       global $post;       $post_id = $post -> ID;       $count_key = 'views';       $count = get_post_meta($post_id, $count_key, true);       if (is_single() || is_page()) {           if ($count == '') {               delete_post_meta($post_id, $count_key);               add_post_meta($post_id, $count_key, '0');           } else {               update_post_meta($post_id, $count_key, $count + 1);           }       }   }   add_action('get_header', 'set_post_views');  

二、将调用显示阅读次数代码加到single模版适当的位置：

<?php get_post_views($post -> ID); ?> views  

调用显示阅读次数代码也可以加到其它模版文件的适当位置。
