activate $_SESSION variable

[ochi]

Hello, I would like to know if it is possible activate a $_SESSION variable in a link:

 

	echo "<a href = logout.php > Logout </a> ;

 

I want activate $_SESSION['logout'] when the link is pressed, so, before than redirect to logout.php I do, $_SESSION['logout'] = true

 

Thanks. Regards!

You cannot set a session variable until the processing returns to the server, as they are set only by PHP code. You could have it as the first thing the logout.php does, but not before processing goes to a php file.

Ops, ok, I'll tell you what I want to do, it cant be so difficult!!!!

 

My structure is: index.php (with user/password autentication) and page2.php and logout.php

 

I want to forbid users write in the browser: http://xx.xx.xx.xx/page2.php it should redirect to index.php. I suposse that the solution is $_SESSION variables, but it's not as simple as it looks.

 

If I activate $_SESSION['page2'] when the user introduce the correct user and password, but he close the browser before than puss the "page2" link, this variable is set and the next time the browser is open it'll be possible write http://xx.xx.xx.xx/page2.php

 

Thanks! regards

To do this, the user will either have to clear the session by using your code to do so in the logout.php script, or have it timeout which is controlled by the session_timeout in the php.ini file.

Hello again, in my php.ini  "session_timeout" doesnt exist. I was looking for it in google, and i found that it is:

session.gc_maxlifetime 

 

I change it to 60 (seconds as it's said in php.ini), after this I tried it waiting for 2 minutes:

 

if(isset($_SESSION['auth'])){
   echo "session establised";
}

 

and "session establised" is writed.

 

Other thing:

; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0

 

When I close the browser and open it again, SESSION variables should exist? they do.

 

Thanks. REgards
