1.封装类

<?php
class DBDA
{
public $fuwuqi="localhost"; //服务器地址
public $yonghuming="root";//用户名
public $mima="";//密码
public $dbconnect;//连接对象
//操作数据库的方法 //$sql代表需要执行的SQL语句
//$type代表SQL语句的类型,1代表查询,2代表增删改
//$shujukuming代表数据库的名称
//如果是查询,返回二维数组
//如果是增删改,返回true或false function Query($sql,$type=1,$shujukuming="house")
{
//造连接对象
$this->dbconnect = new MySQLi($this->fuwuqi,$this->yonghuming,$this->mima,$shujukuming); //判断是否出错
if(!mysqli_connect_error())
{
//如果连接成功,执行SQL语句
$result = $this->dbconnect->query($sql); //根据语句类型判断
if($type==1)
{
//如果是查询语句,返回二维数组
return $result->fetch_all();
}
else
{
//如果是其他语句,返回true或false
return $result;
} }
else
{
return"连接失败";
}
}
}
?>

<?php

//使用加载类

    include("DBDA.class.php");
$db = new DBDA();
$id=$_POST["id"];//传ID
$KeyWord = $_POST["KeyWord"];
$Area = $_POST["Area"];
$SquareMeter = $_POST["SquareMeter"];
$Rent = $_POST["Rent"];
$RentType = $_POST["RentType"];
$HouseType = $_POST["HouseType"];
$sql="update house set KeyWord='{$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)
{
header("location:liebiaoyemian.php");
}
else
{
echo "修改失败";

$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!";
}
?>
