免插件实现WordPress文章阅读次数
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, $count);
- }
- }
二、接下来将下面代码加到主题single模版主循环的中：
-
也就是类似这句的下面
-
三、最后，将调用显示阅读次数代码加到single模版适当的位置：
-
如果想在其它位置显示阅读次数，可以将下面代码也加到functions模版中：
- remove_action（'wp_head'，'adjacent_posts_rel_link_wp_head'，10，0）;
原文：Track post views without a plugin using post meta
代码二：
一、同样将下面代码加到主题functions模版文件中：
- //postviews
- function get_post_views ($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：
- 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。
