if(empty($_COOKIE['username']) || empty($_COOKIE['password'])){ //如果session为空,并且用户没有选择记录登录状
header("location:login.php?req_url=".$_SERVER['REQUEST_URI']); //转到登录页面,记录请求的url,登录后跳转过去,用户体验好。
$user = getUserInfo($_COOKIE['username'],$_COOKIE['password']); //去取用户的个人资料
username = trim($_POST['username']);
$password = md5(trim($_POST['password']));
$validatecode = $_POST['validateCode'];
$ref_url = $_GET['req_url'];
$remember = $_POST['remember'];
$err_msg = '';
if($validatecode!=$_SESSION['checksum']){
$err_msg = "验证码不正确";
}elseif($username=='' || $password==''){
$err_msg = "用户名和密码都不能为空";
}else{
$row = getUserInfo($username,$password);
if(empty($row)){
$err_msg = "用户名和密码都不正确";
}else{
$_SESSION['user_info'] = $row;
if(!empty($remember)){ //如果用户选择了,记录登录状态就把用户名和加了密的密码放到cookie里面
setcookie("username", $username, time()+3600*24*365);
setcookie("password", $password, time()+3600*24*365);
}
if(strpos($ref_url,"login.php") === false){
header("location:".$ref_url);
}else{
header("location:main_user.php");
}
}
}
三,当用户点退出时,清出记录登录状态
代码如下:
//退出登录
function logout(){
unset($_SESSION['user_info']);
if(!empty($_COOKIE['username']) || !empty($_COOKIE['password'])){
setcookie("username", null, time()-3600*24*365);
setcookie("password", null, time()-3600*24*365);
}
}
四、简洁版实例
代码如下:
//读取COOKIE的用户名和密码的值即可
if($_COOKIE['uname']!=''){$CKUNAME = $_COOKIE['uname'];}
if($_COOKIE['pwd']!=''){$CKPWD = $_COOKIE['pwd'];}
echo $CKUNAME;
echo '
';
echo $CKPWD;
?>
//登录,将用户名和密码存入到COOKIE
if($_POST['button']!=''){
$uname = $_POST['uname'];
$pwd = $_POST['pwd'];
//如果输入的加密密码和COOKIE中不一样,那么就加密
if($pwd!=$CKPWD){$pwd = md5($pwd);}
$remember = $_POST['remember'];
if($remember==1){
setcookie("uname", $uname, time()+3600*24*30);
setcookie("pwd", $pwd, time()+3600*24*30);
}
}
?>
