简单的评论回复删除功能，具体内容如下
一、数据库
建立两张表，一是pinglun表；二是huifu表
效果如下：
代码如下：
1.主页面 main.php
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <h1>朋友圈</h1> <div>内容:</div> <div>今天很嗨</div> <div><img src="https://www.jb51.net/picture/timg.jpg"></div><br> <form action="mainchuli.php" method="post"> <input type="text" hidden="hidden" value="zhangsan"> <!--因为没有权限，这里给了一个默认值--> <textarea></textarea><input type="submit" value="评论"><!--评论显示的地方--><!--单击评论提交内容进处理页面--> </form> <!--?php require"DBDA.class.php"; //调用封装类注意修改数据库名 $db = new DBDA(); $sql ="select * from Pinglun"; $arr = $db--->query($sql,1); foreach($arr as $v) { echo" <div>{$v[1]} {$v[3]}</div> <div>{$v[2]}</div> <form action="delchuli.php?id={$v[0]}" method="post"> //删除按钮 <input type="submit" value="删除"> </form> <form action="huifuchuli.php?id={$v[0]}" method="post"> //回复按钮 <textarea></textarea><input type="submit" value="回复"> </form> "; $dc = new DBDA(); $sql1 ="select * from huifu where jieshouid ={$v[0]}"; //查询回复表中的id和传过去的id是不是一样的 $arr1 = $dc->query($sql1,1); foreach($arr1 as $k) { echo "<div>{$k[2]} {$k[3]}</div> <div>{$k[4]}</div> "; } } ?>
2.评论处理页面 pinglunchuli.php
<?php $zhangsan = $_POST["zhangsan"]; $content = $_POST["content"]; $time = date("Y-m-d H:i:s"); require "DBDA.class.php"; $db = new DBDA(); $sql = "insert into Pinglun values('','{$zhangsan}','{$content}','{$time}')"; $db->query($sql); header("location:main.php");
3.回复处理页面 huifuchuli.php
<!--?php $id = $_GET["id"]; //将点击回复的评论id传过来 $Comment = $_POST["Comment"]; //回复文本域中的内容 $me = "me"; //这里是给定义了一个人 $Times = date("Y-m-d H:i:s"); require "DBDA.class.php"; $db = new DBDA(); $sql = "insert into huifu values('','{$id}', '{$me}','{$Times}','{$Comment}')"; $db--->query($sql); header("location:main.php");
4.删除处理页面 delchuli.php
<?php $id = $_GET["id"]; require "DBDA.class.php"; $db = new DBDA(); $sql = "delete from Pinglun where"; if($db->query($sql)) { header("location:main.php"); } else { echo "删除失败！"; }
