Doesn't match the bill entirely, because the behaviour also occurs when
there aren't previous calls to setcookie.

<copypaste>
Cookies must be deleted with the same parameters as they were set
with. If the value argument is an empty string (""), and all other
arguments match a previous call to setcookie, then the cookie with the
specified name will be deleted from the remote client.

I performed some tests:

When you call
setcookie("test ","",0,"/");

The cookie header looks like this:
Set-Cookie: test=deleted; expires=Fri, 06-Sep-02 21:08:27 GMT; path=/

Which deletes the cookie immediately.

But when you create the cookie through the header function with:
header("Set-Cookie: test=; path=/");

The cookie header looks like:
Set-Cookie: test=; path=/

So the cookie is indeed created with an empty value. I think this is an
undocumented feature of the setcookie() function (group, please correct me
if I'm wrong).

I even tried to make sense of RFC2965 [1] ... but RFCs, definitely,
are not my friends.

?????

"$row['xyz']" is not the same as
$row['xyz'] and not the same as
"$row[xyz]"

as far as I can tell only the last two work :)

Ok last time.. I changed to $row[0] and everything is fine with setcookie()
now..

So apparently while header() could set an undefined cookie value,
setcookie() will not do so. Is there documentation on this behavior?

Re: setcookie fails to set cookie!

Ok I changed my code to reflect the associative array $row:

// IF hasLoggedIn IS STILL TRUE WE FOUND THEIR LOGIN INFORMATION - CLOSE UP,
SET COOKIE AND REDIRECT
if ($hasLoggedIn && ($row = mysql_fetch_ass oc($query))) {
setcookie('nord icnet_registrat ion',
"$row['nnet_user_regi strationnumber']", 0, '/');
//header("Set-Cookie:nordicne t_registration= {" .
$row['nnet_user_regi strationnumber'] . "}; path=/");
@mysql_free_res ult($query);
mysql_close($db Conn) or die('Could not close db');
$html .= $font . '<font color=000099>Ta kk for logging inn. For forsatte
' .
"<a href=/membersites/Palogget%20S1.p hp target=_top>kli kk
her</a></font></font>";
} else if (sizeof($_POST) > 0) {
$errorMsg .= $font . '<font color=cc0000><l i>Det finns en problem med
db</li></font></font><p>';
$hasLoggedIn = 0;
}

Guess what? IT STILL FAILED! Unless I specfically use header() instead of
setcookie() it never works within logginn.php (but if I use setcookie()
instead of header() in registrering.ph p with the exact same program logic,
it works, the opposite fails!)

It is stated in the manual that specifying zero for this argument means to
skip it, i.e. not set an expiry time, for the case when you want to use the
other parameters after 'expire'.

"
All the arguments except the name argument are optional. You may also replace
an argument with an empty string ("") in order to skip that argument. Because
the expire and secure arguments are integers, they cannot be skipped with an
empty string, use a zero (0) instead. The following table explains each
parameter of the setcookie() function, be sure to read the Netscape cookie
specification for specifics on how each setcookie() parameter works and RFC
2965 for additional information on how HTTP cookies work.
"

"
expire The time the cookie expires. This is a unix timestamp so is in number of
seconds since the epoch. In otherwords, you'll most likely set this with the
time() function plus the number of seconds before you want it to expire. Or you
might use mktime().

time()+60*60*24 *30 will set the cookie to expire in 30 days. If not set, the
cookie will expire at the end of the session (when the browser closes).
"

So zero does mean 'session cookie'.

I think that I have taken you to the wrong track. Leave the setcookie()
calls as they are and take a look at Pedro's suggestion.

Yes, I think this indeed caused the problem. It seems that when the cookie
function is applied with 0 as the expire time, it does the same as the
header call I suggested.

Re: setcookie fails to set cookie!

OK this is how I did my test:

1) I go to registrering.ph p and register fully, thereby setting the
nordicnet_regis tration cookie. It's all set, everything is fine (uses
setcookie() with 0 time).

2) I close my browser

3) I reboot computer (just for safety sake)

4) I reopen my browser and go to logginn.php

5) I log in, however, setcookie() this time does NOT work, the cookie is not
set because AFTER I click the link to go to another page the
$_COOKIE['nordicnet_regi stration'] value is empty, thus, no cookie. HOWEVER,
header() DOES work in logginn.php!

6) I change the code in registrering.ph p to do header() instead of
setcookie() (remember: setcookie() works, header() does NOT work in
registrering.ph p)

7) I close the browser

8) I reboot computer

9) I reopen browser

10) I go to registrering.ph p Now THIS TIME I have header() and NOT
setcookie() instead of the reverse. I register under a new name and email..
Registration is complete, the cookie SHOULD be set. I get a link to click.
I click the link, go to my next page.. AND NO COOKIE!

So.. this is what happens:

registrering.ph p:

Register -> setcookie('stuf f', $stuff, 0, '/') WORKS -> click link -> there
is the cookie!

Register -> header() FAILS -> click link -> NO COOKIE

logginn.php:

Login -> setcookie('stuf f', $stuff, 0, '/') FAILS -> click link -> NO COOKIE

Login -> header() WORKS -> click link -> there is the cookie!

PHP, nor any other language can teach the programmer the proper and logical
way of thinking. When you know that the third argument of a function that
creates a cookie sets its life time, you must realize that you should pass
it a value larger then zero to create it.

Then you are probably facing a conflict with cookie names which overwrite
each other. Try other names to test this, eg:

header("Set-Cookie: nordicnet_regis tration=1; path=/");

in registering.php and

header("Set-Cookie: nordicnet_regis tration2=1; path=/");

in login.php.

Also, don't forget that once a cookie has been created, it will only be
available after a reload of the page.

So:

<?
header("Set-Cookie: nordicnet_regis tration=1; path=/");
echo $_COOKIE['nordictnet_reg istration'];
?>

Displays nothing.

mysql_fetch_row () does not return the column names as an index!

try mysql_fetch_ass oc()
or use numeric indexes for the colunms:
setcookie('nord icnet_registrat ion', $row[0], 0, '/');

I did what you suggested and it worked.. but why is it that in logginn.php
your header() solution worked, but it FAILED it registrering.ph p to do the
EXACT SAME THING! However, THIS worked in registrering.ph p but FAILED in
logginn.php:

setcookie('nord icnet_registrat ion', $registrationNu mber, 0, '/');

Both have the exact same logic: set cookie -> display text with link -> go
