Returning false is invalid for the session read function, and has caused *MANY* issues with PHP and Sessions. (Check the archives as well as the bugs database. I have a couple in there myself)
Change: return false; To: return ''; And things should start working as expected.

Well, it turns out that write *is* being called, but due to some feature of session write, echo and print don't work, as I read on bugs.php.net. So I put a file-writing mechanism in there and I see it is being called and what was happening. I was trying to do an insert all the time, due to bad logic, so it was cycling to 2, then stopping. Now it seems to work properly. :) As for the session read, I return false when no value is found. > > Jaime Bozza > > > -----Original Message----- > From: Sean LeBlanc [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, January 02, 2002 11:20 AM > To: [EMAIL PROTECTED] > Subject: Re: [PHP] Session troubles > > > On 01-02 07:45, Jaime Bozza wrote: > > I agree.
