核心代码

function.php添加如下代码

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');

调用代码

然后在文章页面single.php的需要显示的位置添加如下代码

阅读次数  ID); ?>

效果

注意：如果部分博主使用的主题是特殊的主题，那么文章页面应该是loop-single.php，把上面方法里面的single.php替换成loop-single.php即可
