php实现评论回复删除功能
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="../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>
";
}
}
?>
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!";
}
