让用户使用cookie登录

Question

I have this forum and I want to keep users logged in if they check the check box that says logged it. So i added this php code to set the cookie :

$year = time() + 31536000;
    if($_POST['remember']) {
setcookie('email', $_SESSION['email'], $year);
}
elseif(!$_POST['remember']) {
if(isset($_COOKIE['remember_me'])) {
    $past = time() - 100;
    setcookie(email, gone, $past);
}
}

But, how do i keep them signed in into my forum using this cookie, I have been stuck on this for some time now.

Answer 1

put this code on top of your login page

if(isset($_COOKIE["email"])){

$_SESSION['email']=$_COOKIE["email"];

header("location: some-page.php");

exit();

}

thats all
