Examples: User authentication


Assuming you’ve followed the previous tutorial and successfully created a User registration system, we’ll now build up from there and create the code to allow users to log into their account.

We need to create a simple login page (login.php) which will have a username field, a password field and a submit button. Information entered on this page by the user will them be used to verify whether or not the username/password combination is valid. If the information is valid, then we’ll simply set a status flag to “true” to indicate that the user is logged in.

The code should look something like this:

PHP:
$user = new User();
$userList = $user->GetUserList("username", "=", $_POST['username']);
if (count($userList) > 0)
{
    $user = $userList [ 0 ];
}
if ($user->password == $_POST['password'])
{
    $_SESSION['userId'] = $user->userId;
    $_SESSION['loggedIn'] = true;
    echo "User is logged in!";
}
else
{
    echo "User is not logged in";
}
