Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Thread: Get current User

    Get current User

    Hi, I am trying to get the current user ID so they can change their password in a content management system. My login code is as follows;

    PHP Code:
    $errorMessage '';
    if (isset(
    $_POST['txtUserId']) && isset($_POST['txtPassword'])) {
    $userId   $_POST['txtUserId'];
    $password $_POST['txtPassword'];
    // check if the user id and password combination exist in database
    $sql "SELECT user_id 
                FROM adminuser
                WHERE user_id = '
    $userId' AND user_password = md5('$password')";
    $result mysql_query($sql) or die('Query failed. ' mysql_error()); 
        if (
    mysql_num_rows($result) == 1) {
    // the user id and password match, 
            // set the session
    $_SESSION['db_is_logged_in'] = true;
    // after login we move to the main page
    header('Location: index.php');
        } else {
    $errorMessage 'Sorry, wrong user id / password';
    I'm then using this to check they are logged in to access pages;

    PHP Code:
    // like i said, we must never forget to start the session

    // is the one accessing this page logged in or not?
    if (!isset($_SESSION['db_is_logged_in']) || $_SESSION['db_is_logged_in'] !== true

    // not logged in, move to login page
    header('Location: login.php');

    Can anyone help? I've tried using $_SESSION['user_id'], and lots of other variations. Any help would be great!

    Fixed... I hadn't sent the info to the session properly!
