wordpress文章页面添加阅读量/点击量，后台并显示阅读量

测试环境

1.前端页面添加阅读量/点击量

进入后台

在functions.php加入

function record_visitors(){
if (is_singular()){
global $post;
$post_ID = $post->ID;
if($post_ID){
$post_views = (int)get_post_meta($post_ID, ‘views’, true);
if(!update_post_meta($post_ID, ‘views’, ($post_views+1))){
add_post_meta($post_ID, ‘views’, 1, true);
}
}
}
}
add_action(‘wp_head’, ‘record_visitors’);
function post_views($before = ‘(点击 ‘, $after = ‘ 次)’, $echo = 1){
global $post;
$post_ID = $post->ID;
$views = (int)get_post_meta($post_ID, ‘views’, true);
if ($echo) echo $before, number_format($views), $after;
else return $views;

在需要的地方增加上

<?php post_views(‘ ‘, ‘ 次’); ?>

比如这个 每个文章的页面文件

2.后台列表显示每篇文章的阅读量 

在functons.php添加：

//在后台文章列表增加一列数据
add_filter( ‘manage_posts_columns’, ‘customer_posts_columns’ );
function customer_posts_columns( $columns ) {
$columns[‘views’] = ‘浏览次数’;
return $columns;
}

//输出浏览次数
add_action(‘manage_posts_custom_column’, ‘customer_columns_value’, 10, 2);
function customer_columns_value($column, $post_id){
if($column==’views’){
$count = get_post_meta($post_id, ‘views’, true);
if(!$count){
$count = 0;
}
echo $count;
}
return;

效果如下
