这是一个登陆信息处理文件

loginProcess.php

<?php

 session_start();

 

 header('Content-Type: text/html;charset=utf-8');

 

 require_once('conn.php');

 $username = $_POST['username'];

 $password = md5(trim($_POST['password']));

 

 

 $sql = "select password from admin where username = '$username'";

 $res = mysql_query($sql,$conn) or die(mysql_error());

 

 if($row = mysql_fetch_assoc($res)){

  if($row['password'] == $password){

   $_SESSION['username'] = $username;

   header('location: adIndex.php');

   exit();

  }

 }

 header('location: login.php?errno=1');

 exit();

?>
