计算页面阅读次数的插件十分多，可是缺陷也有不少，最大的缺陷便是插件装多了网页打开会变慢，其次便是此类插件通常会多出许多咱们不需要的功用，这个时分用代码来完成这个功用是最合适的不过的。
首先把下面这段代码放在functions.php中

// function to display number of posts.
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 to 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);
}
}

然后把下段代码放在single.php中，并保证把代码贴在循环（loop）里。

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

最终一步，你想在哪里显现计数就在哪里加上下面这段代码

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

假如你想在admin面板中也看到计算，就在functions.php中增加如下代码，创立一个检查功用

add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',5,2);
function posts_column_views($defaults){
$defaults['post_views'] = __('Views');
return $defaults;
}
function posts_custom_column_views($column_name, $id){
if($column_name === 'post_views'){
echo getPostViews(get_the_ID());
}
}
