显示WordPress文章阅读次数

WordPress文章添加阅读次数统计,会用到wp-postviews或者wp-postviews-plus插件,本着插件能不用就不用的原则,在这里介绍一个不用插件实现文章阅读次数显示的方法.

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');  

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.
