以下是增删改的做法
3.租房子首页

（4）删除数据处理页面
<?php
$id = $_GET["id"];
var_dump($newsid);
include("DBDA.class.php");
$dx=new DBDA();
$sql = "delete from House where id='{$id}'";
$r = $dx->Query($sql,2);
if($r)
{
header("location:liebiaoyemian.php");
}
else
{
echo "删除失败！";
}
5.编辑页面

6.编辑处理页面
<?php
//使用加载类
include("DBDA.class.php");
$db = new DBDA();
$id=$_POST["id"];//传ID
$KeyWord = $_POST["KeyWord"];
$Area = $_POST["Area"];

//echo $sql;
$attr = $db->Query($sql,2);
//var_dump($attr);
if($attr)
{
header("location:liebiaoyemian.php");
}
else
{
echo "修改失败";
}
7.添加数据页面
<!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>添加页面</title>

<style>
.kong
{
margin:10px 0px 10px 0px;
vertical-align:

</style>
<body>
<form action="tianjiachili.php" method="post">

8.添加数据处理页面
<?php

$db=new DBDA();
//写sql语句
$sql="insert into house values('','{$KeyWord}','{$Area}','{$SquareMeter}','{$Rent}','{$RentType}','{$HouseType}')";
//执行语句
$r=$db->Query($sql,2);//($sql,2) 2代表增删改 错在了2上
if($r)
{
header("location:liebiaoyemian.php");
}
else{
echo "执行失败！";
}
?>
