以下是增刪改的做法
3.租房子首頁
<!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>租房子---首頁</title> </head> <body> <table width="1000px" cellpadding="1" border="1" ellspacing="1"> <tr> <td>關鍵字</td> <td>區域</td> <td>使用面積</td> <td>租金</td> <td>租貸類型</td> <td>房屋類型</td> <td></td> <td></td> </tr>
<?php
include("DBDA.class.php");
$dx=new DBDA();
$sql="select * from house";
$r = $dx->Query($sql,1);
//$attr=$result->fetch_all();
foreach($r as $v)
{
echo
"<tr>
<td>{$v[1]}</td>
<td>{$v[2]}</td>
<td>{$v[3]}</td>
<td>{$v[4]}</td>
<td>{$v[5]}</td>
<td>{$v[6]}</td>
<td><a href=‘bianji.php?id={$v[0]}‘>編輯</a></td>
<td><a href=‘shanchuchuli.php?id={$v[0]}‘ onclick=\"return confirm(‘確定刪除嗎‘)\">刪除</a></td>
</tr>";
}
?>
</table> <br /> <br /> <a href="tianjiashuju.php"><input type="button" value="添加數據"/></a> <a href="duotiaojianchaxun.php"><input type="button" value="搜索查詢" /></a> </title> </body> </html>
（4）刪除數據處理頁面
<?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 "刪除失敗！";
}
5.編輯頁面
<!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>修改房屋數據</title> </head> <body> <!--newsid--><center> <h1>修改房屋數據</h1>
<?php
$id = $_GET["id"];
include("DBDA.class.php");
$dx=new DBDA();
//echo "id";
//var_dump($id);
$sql="select * from house where id=‘{$id}‘";
$r=$dx->Query($sql);
?>
<form action="bianjichuli.php" method="post"> <input type="hidden" name="id" value="<?php echo $r[0][0];?>"/><!--id傳過的ID--> <div>關鍵字:<input type="text" name="KeyWord" value="<?php echo $r[0][1];?>"/></div> <div>區域：<input type="text" name="Area" value="<?php echo $r[0][2];?>"/></div> <div>使用面積:<input type="text" name="SquareMeter" value="<?php echo $r[0][3];?>"/></div> <div>租金:<input type="text" name="Rent" value="<?php echo $r[0][4];?>"/></div> <div>租貸類型:<input type="text" name="RentType" value="<?php echo $r[0][5];?>"/></div> <div>房屋類型:<input type="text" name="HouseType" value="<?php echo $r[0][6];?>"/></div> <div><input type="submit" value="更新"/></div> </form> <!--<a href="chakan.php"><input type="button" value="查看"></a>--> </center> </body> </html>
6.編輯處理頁面
<?php
//使用加載類
include("DBDA.class.php");
$db = new DBDA();
$id=$_POST["id"];//傳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 "修改失敗";
}
7.添加數據頁面
<!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>添加頁面</title>
</head>
<style>
.kong
{
margin:10px 0px 10px 0px;
vertical-align:
}
</style>
<body>
<form action="tianjiachili.php" method="post">
<h3>添加房屋信息頁面</h3>
<div class="kong">
關鍵字：
<input type="text" name="KeyWord"/>
</div>
<div class="kong">
區域：
<input type="text" name="Area"/>
</div>
<div class="kong">
使用面積：
<input type="text" name="SquareMeter"/>
</div>
<div class="kong">
租金：
<input type="text" name="Rent">
</div>
<div class="kong">
租賃類型：
<input type="text" name="RentType"/>
</div>
<div class="kong">
房屋類型
<input type="text" name="HouseType"/>
</div>
<div>
<input type="submit" value="確定"/><!--插入信息-->
<a href="liebiaoyemian.php"><input type="button" value="返回主頁" /></a>
</div>
</form>
</body>
</html>
8.添加數據處理頁面
<?php
//$id = $_POST["id"];
$KeyWord = $_POST["KeyWord"];
$Area = $_POST["Area"];
$SquareMeter = $_POST["SquareMeter"];
$Rent = $_POST["Rent"];
$RentType = $_POST["RentType"];
$HouseType = $_POST["HouseType"];
//造連接對象
include("DBDA.class.php");
$db=new DBDA();
//寫sql語句
$sql="insert into house values(‘‘,‘{$KeyWord}‘,‘{$Area}‘,‘{$SquareMeter}‘,‘{$Rent}‘,‘{$RentType}‘,‘{$HouseType}‘)";
//執行語句
$r=$db->Query($sql,2);//($sql,2) 2代表增刪改 錯在了2上
if($r)
{
header("location:liebiaoyemian.php");
}
else{
echo "執行失敗！";
}
?>
