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>
- <p>内容:</p>
- <p>今天很嗨</p>
- <p><img src="../picture/timg.jpg" width="300" height="200"></p><br>
- <form action="mainchuli.php" method="post">
- <input type="text" hidden="hidden" value="zhangsan" name="zhangsan"> <!--因为没有权限,这里给了一个默认值-->
- <textarea name="content"></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 $v)
- {
- echo"
- <p style="color:blue">{$v[1]} {$v[3]}</p>
- <p style="color:blue">{$v[2]}</p>
- <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 name="Comment"></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 $k)
- {
- echo "<p>{$k[2]} {$k[3]}</p>
- <p>{$k[4]}</p>
- ";
- }
- }
- ?>
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();
- $sql = "delete from Pinglun where id='{$id}'";
- if($db->query($sql))
- {
- header("location:main.php");
- }
- else
- {
- echo "删除失败!";
- }
