To whom it may concern;

I have been building my web site with PHP and MySQL.
This is the first time to utilize PHP programming.

I started to work out LOGIN logics but I have got a
problem with SESSION use. I followed the instruction
of a textbook..but I keep getting the following trouble.

Login page -> Works fine (Storing Variables to SESSION) :-P

1st page (1st time) -> Works fine (Variables are kept in SESSION) :-P

1st page (2nd time) reflesh -> Works..but Variables are gone! Vanished!
2nd page (But the same SESSION ID are used)


I really got confused about this strange behavior of variables.
Somebody, please give me any advice.

1. Are you using sessions ni files or database ?
2. If the variables are gone then I guess in the first page the Variables are not written to sessions.
Try doing print_r($_SESSION); where you feel the variables are vanishing.
Might as well do each time to write variable to check if its actually written.

Thank you for your help.

1. I can't see php.ini file, but I think that it's stored in files.

2. Variables are surely stored in Session on the first page from login page.

3. I used echo("") instead to check it. Session will vanish after moving to
other pages from the first page.

That is really not possible. If stored one page then it can be retrieved from another.
using print_r($_SESSION) you can see all session variables.

So..I'm having a trouble to solve this problem.
I checked it with 'registered' function..but
the first page from login page returns 'true'..
but the second page from the first page returns
'false'. I am sure I didn't unset registered variables...
ID remains the same.

?????

Oh. Then.
Open C:\Windows\php.ini or C:\Winnt\php.ini
Search for register_globals =
Ignore the ones that have ; in front - those are just comments.
If you find anywhere register_globals = Off then change to register_globals = On

I don't see the php.ini file in directories since I'm borrowing provider's server.
I'm using some of functions to change default setting.
I read that it's not good to set register_globals ON due to security reasons.
Is that true?

Whats in the sessions table ? You'll see this using phpinfo();

Thanks. I tried {ini_set("register_globals", 1)},
but the problem remains the same.

If you are changing the name of the cookie for the PHP sessions, make sure that you are doing that for all your pages. I made that mistake, and inadvertently had two sessions open. Oops. If that is okay, make sure that all of your if statements have two == for comparisons.

Otherwise you may want to post your code.
