在文章中显示阅读次数

一 在functions.php尾添加以下代码

function getPostViews($postID){  
    $count_key = 'views';  
    $count = get_post_meta($postID, $count_key, true);  
    if($count==''){  
        delete_post_meta($postID, $count_key);  
        add_post_meta($postID, $count_key, '0');  
        return "阅读次数 0";  
    }  
    return '阅读次数 '.$count;  
}  
function setPostViews($postID) {  
    $count_key = 'views';  
    $count = get_post_meta($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);  
    }  
}

二 在single.php中添加以下代码

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

三 在想显示的地方添加以下代码,如:template-parts/content.php,template-parts/content-single.php

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