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>無標題文檔</title> </head><body><?php $upt = $_GET["upt"];$db = new MySQLi("localhost","root","212333","HouseDB");$sql = "select * from house where id='{$upt}'";$rrr = $db->query($sql);$attr = $rrr->fetch_all();foreach($attr as $v) ?><h1>編輯</h1> <table> <form action="bianjichuli.php" method="post"> <input type="hidden" name="id" value="<?php echo $v[0] ?>" /> <div>關鍵字:<input type="text" name="gjz" value="<?php echo $v[1] ?>" /></div> <div>區域:<input type="text" name="qy" value="<?php echo $v[2] ?>" /></div> <div>面積:<input type="text" name="mj" value="<?php echo $v[3] ?>" /></div> <div>租金:<input type="text" name="zj" value="<?php echo $v[4] ?>" /></div> <div>租賃類型:<input type="text" name="zllx" value="<?php echo $v[5] ?>" /></div> <div>房屋類型:<input type="text" name="fwlx" value="<?php echo $v[6] ?>" /></div> <input type="submit" value="更新" /> </form> <a href="chaxun.php"><input type="submit" value="取消" /></a></table></body> </html>?
編輯處理頁面代碼：
<?php $id = $_POST["id"]; $gjz = $_POST["gjz"]; $qy = $_POST["qy"]; $mj = $_POST["mj"]; $zj = $_POST["zj"]; $zllx = $_POST["zllx"]; $fwlx = $_POST["fwlx"];$db = new MySQLi("localhost","root","212333","HouseDB");$sql = "update house set KeyWord='{$gjz}',Area='{$qy}',SquareMeter='{$mj}',Rent='{$zj}',RentType='{$zllx}',HouseType ='{$fwlx}' where id='{$id}'";$r = $db->query($sql); echo $sql; if($r) {header("location:chaxun.php"); } else {echo "失敗"; }（2）刪除處理頁面代碼
<?php$aa = $_GET["ass"];$db = new MySQLi("localhost","root","212333","HouseDB");$sql = "delete from house where id='{$aa}' ";$r = $db->query($sql);if($r) {header("location:chaxun.php"); } else {echo "失敗"; }4.條件查詢頁面
