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
