I need a bit of help and can't seem to figure out what is going on. I can't get this class to read data fromt he session properly. After login, I call a "login_process.php" page which includes the class file, selects the database where I have the table stored that holds the session data, I add data to the $_SESSION var and during debugging all the data gets stored in $_SESSION just fine (inside this page); I checked the database and its all there as well, so I know its set up properly (at least part of it). However, when I do a redirect to the landing page and try to use the $_SESSION to retrieve the username (i.e $_SESSION["username"]) nothing shows up. On the landing page,I include a header page. Inside the header I have included the class for the php session script and I've instantiated an object. I've also selected the appropriate database, just like I did in the login_process.php page. When I var_dump($_SESSION) it says there is nothing there, eventhough in the login_process.php page I set everything and its still inside the database table. If I hardcode a $_SESSION["something"]="hi mom"; in the landing page, then dump the $_SESSION, it shows the "hi mom" value and the "something" variable. This is giving me the impression that at this point the PHP is still using "file-based" storage, instead of the database...I confirmed that by loooking into the database where the session var should be stored and its not there. I updated the php.ini file directly on my local computer to 'session.save_handler = user', but then it breaks my phpmyadmin stuff and created more problems for me.

I've been debugging for hours and am at a loss. Is there anyone who has some advice, or tips that could help me? It's odd to me that it will work in the login_process.php page, but when that page redirects using header(location), the receiving page can't see the variables?

Thanks in advance.

Aaron

Mr Aron,

I'm new to this class as well but since I understand a little bit about this code so I think I should share with you. Actually, we can store our session information example $_SESSION["value1"]= $username and $_SESSION["value2"]=$userlevel only by follow the exact code and I have try to change such as $_SESSION["username"]=$username and it cannot work, and the data in the field session_data inside the session_data table is empty. Since, the data in the filed session_data is array data type so you can retrieve your data such as $username by type print_r($_SESSION["value1"]); and it will print the username for you and also print_r($_SESSION["value2"]); for userlevel. I've try this code for my login testing and it work fine, but I have another problems, I don't know how to set timeout for the session. If you know it, I'm really appreciated if you can help me on it.
