（4）删除数据处理页面

复制代码
复制代码
<?php
$id = $_GET["id"];
var_dump($newsid);

include("DBDA.class.php");

$dx=new DBDA();

$sql = "delete from House where id='{$id}'";

if($r)
{
    header("location:liebiaoyemian.php");
}
else
{
    echo "删除失败！";
}
复制代码
复制代码

5.编辑页面

//var_dump($id);

$sql="select * from house where id='{$id}'";
$r=$dx->Query($sql);

?>
复制代码
复制代码
<form action="bianjichuli.php" method="post">

<input type="hidden" name="id" value="<?php echo $r[0][0];?>"/><!--id传过的ID-->

<div>关键字:<input type="text" name="KeyWord" value="<?php echo $r[0][1];?>"/></div>

</form>
<!--<a href="chakan.php"><input type="button" value="查看"></a>-->
</center>
</body>
</html>

复制代码

6.编辑处理页面

复制代码
复制代码
<?php
 
//使用加载类
    
    include("DBDA.class.php");
    $db = new DBDA();
    $id=$_POST["id"];//传ID
    $KeyWord = $_POST["KeyWord"];

$sql="update house set KeyWord='{$KeyWord}',Area='{$Area}',SquareMeter='{$SquareMeter}',Rent='{$Rent}',RentType='{$RentType}',HouseType='{$HouseType}' where id='{$id}'";// where id='{$id}

//echo $sql;
     
    $attr = $db->Query($sql,2);
    //var_dump($attr);
    if($attr)
    {

    }
    else

 7.添加数据页面

复制代码
复制代码
<!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>


</head>
<style>
    .kong
    {
        margin:10px 0px 10px 0px;
        vertical-align: 
    }
</style>
<body>
<form action="tianjiachili.php" method="post">
    
 <h3>添加房屋信息页面</h3>   

    <div class="kong">
        关键字：

    <a href="liebiaoyemian.php"><input type="button" value="返回主页" /></a>
</div>
</form>    

</body>
</html>
复制代码
复制代码

8.添加数据处理页面

复制代码
复制代码
<?php 
//$id = $_POST["id"];
$KeyWord = $_POST["KeyWord"];
$Area = $_POST["Area"];
$SquareMeter = $_POST["SquareMeter"];
$Rent = $_POST["Rent"];
$RentType = $_POST["RentType"];
$HouseType = $_POST["HouseType"];

//造连接对象
include("DBDA.class.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！";
}
 ?>
