Re: $_SESSION['loggedin'] not working properly

When a user logs in to my site http://iwantyourquestion.com I set
$_SESSION['loggedin'] to true if his username and password are OK.
When he calls a page I check if $_SESSION['loggedin'] is true. If it
not I ask him to log in.
Every page has at the start:
session_start();
ob_start();
You forgot the part that begins <?php and *DOES NOT* have a DOCTYPE
line or any white space before it.
A user just told me that he was asked to log in again after he entered
his username and password. If they were incorrect he would be sent
back to the login page, but that was not what happened. He was asked
to log in again.
This is believable if he started a new session, which could happen a
number of ways:
- The user's browser doesn't accept cookies.
- The user cleared cookies.
- The user exited and restarted the browser, and your page uses
session cookies.
- The cookie expired. I'm not sure what your expire time is, but maybe
the user stayed logged in over a long lunch or weekend?.
- One of your pages forgot the session_start() call.
The only reason I can think of is that $_SESSION['loggedin'] was not
stored correctly. But why not?
Losing the session cookie is a major possibility. So also is running
out of disk space to store session data in.
When he tried to log in a second time everything worked fine. He was
allowed in.
Has anyone else experienced this and know why it happens?
