租房子练习题:重要颜色

1.模仿get传值到处理php页面:<a href=‘shanchu.php?c={$v[0]}‘ onclick=\\"return confirm(‘确定删除吗?‘)\\">删除</a>

2.删除页面显示确定删除提示框:<a href=‘shanchu.php?c={$v[0]}‘ onclick=\\"return confirm(‘确定删除吗?‘)\\">删除</a>

 主页面:

<body> <table border="1" cellpadding="0" cellspacing="0" width="90%"> <tr> <th></th> <th></th> <th>关键字</th> <th>区域</th> <th>使用面积</th> <th>租金</th> <th>租赁类型</th> <th>房屋类型</th> </tr> <?php include("../fzl/czy.class.php"); $db = new czy(); $sql = "select * from house"; $attr = $db->Query($sql); foreach($attr as $v) { echo "<tr> <td><a href=‘gai.php?c={$v[0]}‘ \\">编辑</a></<td> //c={$v[0]}是把主键值赋给c 模仿get传值 点哪条数据就通过主键值把数据通过get方式到修改页面 <td><a href=‘shanchu.php?c={$v[0]}‘ onclick=\\"return confirm(‘确定删除吗?‘)\\">删除</a></<td> <td>{$v[1]}</td> <td>{$v[2]}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <td>{$v[5]}</td> <td>{$v[6]}</td> </tr>"; } ?> </table> <a href="add.php"><input type="submit" name="tj" value="添加新数据"/></a> <a href="ss.php"><input type="button" value="搜索" /></a> </body>

添加数据主页面:点取消时 href="主页面.php"  点添加时 action="主页面处理页面.php"

<body>
<?php
include("../fzl/czy.class.php");
$db = new czy();
$sql = "select * from house";
$attr = $db->Query($sql);
?>
<form action="azucl.php" method="post">
<div>关键字<input type="text" name="guanjianzi" /></div>
<div>区域<input type="text" name="area" /></div>
<div>使用面积<input type="text" name="areaa" /></div>
<div>租金<input type="text" name="money" /></div>
<div>租赁类型<input type="text" name="leixing" /></div>
<div>房屋类型<input type="text" name="house" /></div>
<input type="submit" value="添加" /><a href="azu.php"><input type="button" value="取消" /></a>
</form>
</body>

 添加数据主页面处理页面:href:"主页面.php"

<?php
include("../fzl/czy.class.php");
$db = new czy();
$guanjianzi = $_POST["guanjianzi"];
$area = $_POST["area"];
$areaa = $_POST["areaa"];
$money = $_POST["money"];
$leixing = $_POST["leixing"];
$house = $_POST["house"];
if($house != "" && $guanjianzi != "" && $area != "" && $areaa != "" && $money != "" && $leixing != "" )
{
    $sql = "insert into house values(‘‘,‘{$guanjianzi}‘,‘{$area}‘,{$areaa},{$money},‘{$leixing}‘,‘{$house}‘) ;";
    $b = $db->Query($sql,0);
    if($b)
    {
        header("location:azu.php");
    }
    else
    {
        echo "添加失败";    
    }
}
else
{
    echo "输入的内容不能为空";    
}
?>

修改数据主页面:确认修改按钮  action="修改处理页面.php"    点取消时 href="主页面.php"

把数据放在文本框<text>里面:<input type="hidden" value="<?php echo $arr[0] ?>" name="haoma" />

<body> <?php $haoma = $_GET["c"]; include("../fzl/czy.class.php"); $db = new czy(); $sql =" select * from house where ids = ‘$haoma‘"; $attr = $db->Query($sql); $arr = $attr[0];//把二维数组$attr 变为一维数组$arr ?> <form action="gaichuli.php" method="post"> <div><input type="hidden" value="<?php echo $arr[0] ?>" name="haoma" /></div> <div>关键字<input type="text" value="<?php echo $arr[1] ?>" name="guanjianzi" /></div> <div>区域<input type="text" value="<?php echo $arr[2] ?>" name="area" /></div> <div>使用面积<input type="text" value="<?php echo $arr[3] ?>" name="areaa" /></div> <div>租金<input type="text" value="<?php echo $arr[4] ?>" name="money" /></div> <div>租赁类型<input type="text" value="<?php echo $arr[5] ?>" name="leixing" /></div> <div>房屋类型<input type="text" value="<?php echo $arr[6] ?>" name="house" /></div> <input type="submit" value="确认修改" /> <a href="azu.php"><input type="button" value="返回" /></a> </form> </body>

修改处理页面: header("location:主页面.php");

<?php
include("../fzl/czy.class.php");
$db = new czy();
$haoma = $_POST["haoma"];
$guanjianzi = $_POST["guanjianzi"];
$area = $_POST["area"];
$areaa = $_POST["areaa"];
$money = $_POST["money"];
$leixing = $_POST["leixing"];
$house = $_POST["house"];
if($house != "" && $guanjianzi != "" && $area != "" && $areaa != "" && $money != "" && $leixing != "" )
{
    $sql ="update house set keyword=‘{$guanjianzi}‘,area=‘{$area}‘,squarmeter={$areaa},rent={$money},renttype= ‘{$leixing}‘,housetype= ‘{$house}‘ where ids=‘{$haoma}‘ ";
    $t = $db->Query($sql,0);
    if($t)
        {
            header("location:azu.php");
        }
    else
        {
            echo "修改失败<a href=‘azu.php‘>返回主页面</a>";    
        }
}
else
    {
        echo "输入的内容不能为空";    
    }
?>

删除处理页面:header("location:主页面.php");

<?php
$haoma = $_GET["c"];
include("../fzl/czy.class.php");
$db = new czy();
$sql = (" delete from house where ids = ‘{$haoma}‘");
$db->Query($sql,0);
header("location:azu.php");
?>

搜索页面/包括修改处理:

1.多条件查询

2.去重查询

3.关键字查询变色

.a{ float:left}
.b{ float:left}
.c{ float:left}
#bbb{ margin-top:10px}
</style>
