I am developing my 1st php solution for my own use (To manage my accounts etc). I am providing users with a username and password which I am validating by checking their data in the relevent mySql tables. This is no problem.
The problem I have is that once they succesfully log in I want to create some sort of identifier that means if they try to go straight to one of the pages without 1st logging in I want them directed back to the login screen.
This project works like a web based control panel.
