Cookie Value Not Updating

[cwb]

I am trying set a cookie on my site for an id. The cookie sets fine but I want the cookie to update if the value of the cookie changes. I am using the code below but it is not updating the value of the cookie when it changes.

I have this code on the top of every page on the site:

if (isset($_COOKIE['id'])) {
  if ($_COOKIE['id'] != $id) setcookie("id", $id, time()+3600);
} else {
  setcookie("id", $id, time()+3600, "/", ".mydomain.com", 0);
} 

Thanks for any help

Hmm, try this:

if (isset($_COOKIE['id'))
{
    if ($_COOKIE['id'] != $id)
    {
        setcookie("id", $id, time()+3600);
    }
}
else
{
    setcookie("id", $id, time()+3600);
}

That code is giving me all kinds of errors... I try to fix one but then get another.
Thanks for trying though

Oops, my bad... stupid parse errors

if (isset($_COOKIE['id']))
{
    if ($_COOKIE['id'] != $id)
    {
        setcookie("id", $id, time()+3600);
    }
}
else
{
    setcookie("id", $id, time()+3600);
}

Ok, got the code fixed.. but still didn't work

We'll need to see some code... I just tested that snippet of coding in a web browser and it works fine.

I used the code you gave me.. not sure what else could I give?
Maybe it is a problem with my browser. Got an old computer.
I'll have some friends test.

Thanks for the help.

Having the code on the top of every page wouldn't hurt things would it?

Any session or cookie functions such as setcookie and session_start MUST be put at the TOP of the page otherwise you'll get parse error such as "Headers already sent!"
