简单的评论回复删除功能
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
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> </head> <body> <h1>朋友圈</h1> <div>内容:</div> <div>今天很嗨</div> <div><img src="../picture/timg.jpg" width="300" height="200" /></div><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 $v) { echo" <div style='color:blue'>{$v[1]} {$v[3]}</div> <div style='color:blue'>{$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 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 $k) { echo "<div>{$k[2]} {$k[3]}</div> <div>{$k[4]}</div> "; } } ?> </body> </html>
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！";
}
