  1. Hi Larry, I have encountered a really weird problem (well weird to me) re the server not being able to write a session cookie reliably but it always gets set first go in localhost. I had to include a do-while loop in the production version until the session data were available but I don't know how many times the loop gets executed before the session cookie gets set. Can you offer any guidance on how to debug this? Am using IE11 and Firefox 62.0 Thanks as always, Necuima
  2. Hi Larry, On page 90 you define the clean_session function but I can't figure out how to invoke it. I tried 'session_clean(seconds)' to no avail. Can you please guide me. Thanks, Necuima.
  3. Hi Larry, Just FYI I modified the db_sessions code (pp 82..) for PDO - after a few pitfalls it works beautifully. Thanks for the base code to work with. Cheers, Necuima.
  4. I was hoping that someone might be able to provide a few lines of code that would automatically log the user out after 20 or 30 minutes of inactivity. Maybe the code could be placed in the config.inc.php file so that it gets run frequently? (Note: I am using the "First Site" as created in chapters 1-6 of Larry's book.) Thanks!
  5. In Chapter 19, the $_SESSION['customer_id'] variable is often used for things like isset($_SESSION['customer_id']) why though can't we use other table columns that are like customer_id in the $_SESSION[] for example $_SESSION['order_id'] In chapter 19 also, the $_GET['id'] is the same id as the customer's. Why is it the same? Where does it get declared as the same, I have searched through the scripts and I don't see it. I am trying to create a script where users can view their past orders. The trouble I am having is calculating the total amount of the order in the checkout.php scrip
  6. Hello, Just read through sessions in Ch3. There is one thing I did not get. How do I obtain the session_id(). It seems to be always empty. I even tried to set it in the read_session() but still no effect. Is this the expected behavior or am I missing anything? Cheers
  7. Hi Larry, and all other experts, I am following your guide on setting up yii for my site, and I am at the stage where I want to design all the database tables before I run Gii for the CRUD/model/view/controllers setups, now I wanted to save the session data onto a database table and have as little possible info in cookies (i'd rather not use cookies unless the user specifically wants to, or i may need to to validate whether the user is using the same machine). anyway, i got the session thing to work with the mysql db and it created the table fine... now i want to try to modify the tabl
  8. SOLVED for solution see the last part of my first post _______________________________________________________________________ hi , i read chapter 3 and try to pass session_set_save_handler with an object, here's the code for my session handler class: <?php class MySessionHandler implements SessionHandlerInterface { protected $conn = NULL; public function open($savePath, $sessionName) { if(is_null($this->conn)) { $dsn = 'mysql:host=localhost;dbname=php_advanced'; $username = 'root'; $password = 'passw
  9. I am a little confused about session/cookies automatic interaction/behavior. You explained that it is preferable to store the email (users.email) in session and not the userID (users.userID) because the email is harder to forge than userID which is a number, hence leaving the site exposed to XSS attacks. However, for whatever operations the user may be allowed to do, like CRUD operations, you will need the id of the table for that specific action (let's say "posts" table, for example, we will need something like posts.postID) and the userID. To get users.userID from users.email we will hav
