smileyriley21 Posted March 13, 2006 Share Posted March 13, 2006 Hi, I am experiencing an intermittant error "Call to a member funtion on a non object" using php objects as session variables. My program structure stores the customer object as session variables. For instance, when a customer logs in I generate a customer object and store this as their session variable (with name, email etc etc). This gives me easy access to the information I need, when I need it. Every now and then the error "Call to a member function on a non object" occurs. However, this is intermittant and does not follow any pattern. I have experience this error when a customer continually refreshes the page. In this instance the session var is lost and therefore the object error occurs. Here is an example.. $cust= unserialize($_SESSION['cust']); $cust->doSomthing(); $cust= serialize($cust); If the client refreshes the page whilst the function doSomthing() is called, the session var is lost. Really, I need some advise on this? How can I ensure the session variable is not lost?Many thanks, in advance Dak Quote Link to comment https://forums.phpfreaks.com/topic/4859-session-objects-and-errors-0/ Share on other sites More sharing options...
