[PHP] Re: coockie expiration problems

2002-09-02 Thread nicos 

Hi,
I see really nothing wrong in your example. Did you tried to verify with
isset() if the cookie is still here or not?
And well, you should use double quote on setcookie(referrer, $user_id,
time()+10);
You call should be also $_COOKIE['referrer'] and not $_COOKIE[referrer].

 Hi there,

 I am trying to save a var inside a cookie for a certain time (in this
 example 10s):
  setcookie('referrer', $user_id, time()+10); //expires in one hour

 Now I would like to get the value, but only if the coockie is valid (if
 cockie not older than 10 s in this example)
 echo 'referrer: '.$_COOKIE[referrer];

 Unfortunatelly this does not work, the cockie value is always valid, even
 after expiration time.

 What am I doing wrong?

 Thanx for any help on that,

 Andy

2002-09-02 Thread andy 

OK, I found the reason, but not the solution yet:

The cookie time during setting is the time taken from the server. The time
for checking the coockie is the time of the local machine!!

So what can I do if I would like to last the coockie for 1 hour and the
person is sitting on the other site of the world running 10 hours time
difference? Puhh.. maybe I am wrong, but this is how it seems to be.

Any ideas?

Andy

According to netscape the cookie date value is expected to be in the
GMT time zone only so that is not the problem. This is more likely the
cause (from Netscape again)

quote
The expires header lets the client know when it is safe to purge the mapping
but the client is not required to do so.
A client may also delete a cookie before it's expiration date arrives
if the number of cookies exceeds its internal limits
/quote

What you will have to do is encode your time in the value passed with
the cookie and do your own checking...ignoring it if it is older than
10 seconds
