WordPress回复/评论本文可见

给WordPress添加一个实用的小功能,那就是回复可见,评论文章才能见到隐藏内容。 在主题目录下找到functions.php文件,在合适位置添加下方的代码:
    // 回复可见
    function reply_to_read($atts, $content=null) {   
        extract(shortcode_atts(array("notice" => '<p class="reply-to-read"><font color="#ff0000">温馨提示: </font>此处为隐藏内容,需要<a href="#respond" title="评论本文">评论本文</a>后才能查看.</p>'), $atts));   
        $email = null;   
        $user_ID = (int) wp_get_current_user()->ID;   
        if ($user_ID > 0) {   
            $email = get_userdata($user_ID)->user_email;   
            //对博主直接显示内容   
            $admin_email =  get_userdata($user_ID)->user_email ;//博主Email   
            if ($email == $admin_email) {   
                return $content;   
            }   
        } else if (isset($_COOKIE['comment_author_email_' . COOKIEHASH])) {   
            $email = str_replace('%40', '@', $_COOKIE['comment_author_email_' . COOKIEHASH]);   
        } else {   
            return $notice;   
        }   
        if (empty($email)) {   
            return $notice;   
        }   
        global $wpdb;   
        $post_id = get_the_ID();   
        $query = "SELECT `comment_ID` FROM {$wpdb->comments} WHERE `comment_post_ID`={$post_id}  and `comment_author_email`='{$email}' LIMIT 1";   
        if ($wpdb->get_results($query)) {   
            return do_shortcode($content);   
        } else {   
            return $notice;   
        }   
    }  
    add_shortcode('reply', 'reply_to_read');  
使用方法: [reply-]需要隐藏的内容[/reply],需要把[reply-]的“-”去掉 [reply]测试回复可见[/reply]
