php简单的留言板与回复功能具体实现_php实例
在网上找了这方面的教程 但是基本就是没有人说什么 然后在某一天看见一个PHP程序设计出了一张类似这样的数据库设计图之后就有了很多领悟!下面是数据库的结构图
下面我们就来继续一下介绍
id 这个算是父Id 可以通过这个id来查询 在这个id下是否有子id 同时也可以记录这个是那条留言的id
son_id 这个是子id 然后通过这个id 可以找到相对应的父id
news_id 记录文章的id
sender_author 接受留言的人
receiver_author 发送留言的人
content 留言的内容
status 在有人回复你的帖子的时候 这个值从0转为1时候 该消息不在显示 如果没点击进去 该消息依然存在
time 记录留言的时间
留言板回复思路
当发送方(也就留言的人)要到该文章下留言或者回复的的时候就需要接收方(也就文章的作者或者要被回复的人)来接收。单数据库语句查询到这个键sender_author和receiver_author 的是就会知道接收方是谁和发送方是谁了。然后在根据这个判断来显示出回复内容
提示你有一条新的消息思路
当发送方发送消息的时候 这个status的值默认为0 就是提示接收发 你有一条新的消息。当点击进去的时候 调用数据库修改语句把指定的值修改成为1 这样就不显示了
查看评论的时候 的数据库操作语句
function message($id){
$query = $this->db->query("SELECT * FROM message WHERE news_id = '$id'");//或者文章id后查询里面所有评论
return $query->result();
}
这个是获取父的留言内容的代码
留言用户:receiver_author;?> 留言内容:content?>
用户是否登陆 并给予留言权限
这个是显示了 获取指定的父id 之后来显示他里面的全部子id 和留言内容
这里是楼 用户:receiver_author;?>
留言内容:content?>
$query = $this->db->query("select * from message where son_id ='$sel->id' order by id");//获取指定父id的子回复
$revis = $query->result();
foreach($revis as $row){?>
sender_author == $row->receiver_author){echo $row->sender_author;}
else{ echo $row->sender_author."回复了:".$row->receiver_author;}?>
内容是:content?>
这个是实现之后的效果图片 留言板已经实现了 留言内容回复
然后这个是实现了 回复你的时候 会显示你有一条新的留言

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
