beginner cookie think

hi all,

Trying to get those cookies to work but they wont...

Doing this. Have a page login.php wich tests the user and pass. If they are
correct a cookie is set with one variable like this: setcookie
("cookieUser", $user);
then the browser is sent with header("Location: spelersPage.php"); to
another page.
I there try to read the cookievariable cookieUser on the spelersPage.php
like this.
<?
$test = $_COOKIE["cookieGebruiker"];
echo "|$test";
?>

without any succes. Someone has an idea. The page is im my Thrusted sites
list...

kind regards
Stijn

Your problem is likely due to a limitation to cookies, not php.

A refresh has to have occured before your cookie becomes available to your
environment thus if you were to refresh your browser a couple of times you
should get your cookie. If not, as a test, I tend to use phpinfo(); alot
when doing various tests on form and cookie variables... Try writing the
following few lines to a php script file of its own (call it cookieTest.php
for our example).

<?
// For our test, our cookie will be the words "hello world" followed by the
eleven digit timestamp generated by time();
$ourCookie="hello world" . time();
setcookie("ourTestCookie", $ourCookie);
print("<br>1 = The cookie we just set is $ourCookie<br>");
print("<br>2 = However the cookie that is already baked is:
$_COOKIE[ourTestCookie]");
phpinfo();
?>

View this code in a page of its own... refresh the page a few times and
examine the values that are output - and while you're at it, examine the
output of phpinfo();.

I would expect that you should find something like

1 = The cookie we just set is hello world12345678901
2= However the cookie that is already baked is:

The next time your refresh your browser, you should find the output
something like the following

1 = The cookie we just set is hello world12345678911
2= However the cookie that is already baked is:hello world12345678901

Note that the cookie the first time was sent to the browser but could not be
read yet (until you re-freshed the browser).

Hi,

Thanks for your reply. Indeed, when I refresh the page where the cookie is
defined, the cookievariable is set. What is the best way to overcome this
cookielimitation? Do I have to use some sort of javascript refresh while the
setcookie page is accessed or is there an other way (pref. in php) to
overcome this problem...
I want to use the cookie for an automated login (often used with forum
systems where 'Log me on automatically each visit' is used ). How do they
deal with this limitation?

regards
Stijn

Hi Stijn

To overcome the need to refresh, set the cookie's value
in *both* the HTTP response header and the $_COOKIE array
at the same time:

$_COOKIE['mycookie'] = 'chocolate chip';
setcookie('mycookie', $_COOKIE['mycookie']);

If you synchronize the HTTP response and the $_COOKIE
array on the first page that sets the cookie, you won't
have to refresh.
