题目要求
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falsefunction 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falsereturn $result; }}else{return"连接失败"; } } } ?>
2.租房子页面
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>租房子---首页</title> </head> <body><table width="1000px" cellpadding="1" border="1" ellspacing="1"> <tr><td>关键字</td> <td>区域</td> <td>使用面积</td> <td>租金</td> <td>租贷类型</td> <td>房屋类型</td> <td></td> <td></td> </tr><?phpinclude("DBDA.class.php");$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]}'>编辑</a></td> <td><a href='shanchuchuli.php?id={$v[0]}' οnclick=\"return confirm('确定删除吗')\">删除</a></td> </tr>"; }?></table> <br /> <br /> <a href="tianjiashuju.php"><input type="button" value="添加数据"/></a> <a href="duotiaojianchaxun.php"><input type="button" value="搜索查询" /></a> </title> </body> </html>
3.删除数据处理界面
<?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($r) {header("location:liebiaoyemian.php"); } else {echo "删除失败！"; }
4.编辑页面
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>修改房屋数据</title> </head> <body> <!--newsid--><center> <h1>修改房屋数据</h1><?php$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传过的ID--> <div>关键字:<input type="text" name="KeyWord" value="<?php echo $r[0][1];?>"/></div> <div>区域：<input type="text" name="Area" value="<?php echo $r[0][2];?>"/></div> <div>使用面积:<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>租贷类型:<input type="text" name="RentType" value="<?php echo $r[0][5];?>"/></div> <div>房屋类型:<input type="text" name="HouseType" value="<?php echo $r[0][6];?>"/></div> <div><input type="submit" value="更新"/></div> </form> <!--<a href="chakan.php"><input type="button" value="查看"></a>--> </center> </body> </html>
5.编辑处理 假面
<?php//使用加载类include("DBDA.class.php");$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"; }
6.数据添加
<!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：<input type="text" name="KeyWord"/></div><div class="kong">区域：<input type="text" name="Area"/></div><div class="kong">使用面积：<input type="text" name="SquareMeter"/></div><div class="kong">租金：<input type="text" name="Rent"></div><div class="kong">租赁类型：<input type="text" name="RentType"/></div><div class="kong">房屋类型<input type="text" name="HouseType"/></div> <div><input type="submit" value="确定"/><!--插入信息--><a href="liebiaoyemian.php"><input type="button" value="返回主页" /></a> </div> </form> </body> </html>
7.数据添加的处理界面
<?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！"; }?>
8.搜索界面
