Hello,
I am building a php / mysql website with the usual login / fancy php scripts etc. I have a little annoying issue and I think the answer may lie in my php sessions. When I use my login script, sometimes I am logged in and sometimes I am kicked back to my home page. Also, when i am logged in I am sometimes kicked back out when I click an internal link - very annoying indeed. I have posted an example script below detailing my use of sessions - any comments are greatly appreciated. 🙂
Regards,
Susan
