wp/wordpress文章页面添加阅读量/点击量，后台并显示阅读量

wordpress默认不带阅读量的，现在加上。在function.php加入代码

1、前端加入阅读量和点击量

//增加文章阅读次数
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;
} 

　　在线显示的地方，例如singe.php页面加入：

//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;
}
