login_1.php內容如下
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <?php error_reporting(0); if(!isset($_POST['submit'])){ exit('非法訪問!'); } $name=$_POST['loginName']; $password=$_POST['loginPwd']; include('connect.php'); if($name && $password){ echo "come in"; $sql="select * from admin where adName='$name' and adPwd='$password' "; $res=mysql_query($sql); echo "$res"; echo "$name"; $test=mysql_fetch_array($res); if($test && strcmp($name,'admin')==0){ header("location:index.php"); echo "finally"; exit; }else{ echo "fail to login"; exit; } mysql_free_result($res); mysql_close($conn); } ?>
connect.php內容如下
<?php
$conn=mysql_connect('localhost','root','') or die("連線失敗".mysql_error());
mysql_select_db('door',$conn) or die("選擇資料庫失敗".mysql_error());
mysql_query("set names gb2312");
?>資料庫設計 如下
