Hello everyone. I'm trying to set up a class inside the sessions from php and request it from other pages but when I try to do that, I only get null. Could someone help me please? Thank you.

Can you give a code piece about your Giris() method. You need to set your session on this method. Then get session variables by session_start method.

Have a nice day.

a possible explanation: before you get the YETKILI object back from the session with $yet = $_SESSION['YETKILI']; you must ensure that the class definition for YETKILILER is available. i.e. in index.php, make sure you have used include or require on the file that holds the YETKILI class.

   $yetkili->YETKILI_SIFRE=$YETKILI_SIFRE;
   $_SESSION['YETKILI'] = serialize($yetkili);

     $yetkili =  unserialize($_SESSION['YETKILI']);
     $test = $yetkili->YETKILI_ID;

You will need to include your class in the pages where you are accessing the object via the session. I suggest you create a separate file, eg class_lib.php, where you define all your classes and then use include or require in the pages that use it.

Also, you will need to serialize your object before assigning it to a session and then unserialize it on the other end.

EDIT: Also, you will need session_start(); in both pages or in a page that they both include.
