首先在文章或页面前部分模板声明PostViews函数。

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

然后在需要展示PostViews的地方添加以下代码。

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

最后在主题functions.php文件添加函数代码。

<?php

// 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);
    }
}

?>
