Get value in a cookie ?

Anon

Hello everybody.
How do I get the value from a cookie which was set in a previous session ???
When I try to print the value with HTTP_COOKIE_VARS["cookie_name"] or with $cookie_name, nothing is shown...
Is there another way to access the cookie ?

Thanks 4 your answer ;-)

Well if the previous session has expired then you don't, session cookies are only temporary so they either disapear when the user closes the browser window or the timer runs out. If you want to use a cookie that is independant of the session then I suggest using the setcookie() function, like so.

setcookie ("TestCookie", "testvalue",time()+3600); / expire in 1 hour /

Thou I would set the expiry time to something a bit longer than an hour.

Now this cookie would be sent to your server everytime the user accessed it so it would be avaliable through both the $TestCookie and the HTTP_COOKIE_VARS["TestCookie"] variables.

Hope this solves you dellema... 🙂

Thanks for your answer.

Here's how I set my cookie:

$now = time();
setcookie("concours", "1", $now+(3600247), "/");

This cookie is indeed available in the current session but not in another session. Does it come from my script or from anything else (IE, ...) ?

Thanks again

Hmmm thats weird, I've been working with cookies and sessions for quite some time now and I never ran into this problem.

FYI: cookies are sent back and forth using a little header string before the document contents are sent, and as far as I know the browser sends those strings everytime it accesses a file from the server that the cookie was created on.

Maybe you should show more of your code here, it might be that something else in interfearing with the cookies?...thou I don't know what could...cause session cookie data is actualy set with the session_register() function and all other cookies are supposed to be completely independant of the session stuff.

Thanks 4 your help.

I changed something in my script and now it works... I don't know why or how but it seems to work.

See you

Good to hear, I'd love to know what it was that was interfering with the cookies, so I can avoid the same problem in the future...
