Cookie Problem

webmasternovis

Hi all,

I set a cookie in a subfolder of my site, with the following code:

setcookie("userid", $row[id], time()+60*60*24*360, "/","www.domain.com");

I try to access this from my higher level pages, such as domain.com/page.php. It can't access it for some reason though, does anyone know why? I thought the forward slash on the fourth parameter meant that the cookie applied to the whole site.

Thanks,
Mike

Try setting the last arg to ".domain.com" (note the leading ".").

That's exactly what it does... mostly. It means the cookie applies to the whole site within the domain name given. Since you specified "www.domain.com" this cookie would NOT be valid for http://domain.com/myscript.php (nor any other path on "domain.com" for that matter).

As NogDog pointed out, using ".domain.com" as the domain parameter means the cookie should be allowed on any subdomain of "domain.com" .

Hi all,

I've just tried it, so my code reads like this now:

setcookie("userid", $row[id], time()+60*60*24*360, "/",".domain.com");

Yet when I try and echo my cookie on a page in the root of my site, nothing appears. Is that the correct code?

Thanks,
Mike

Looks like it... have you tried echo'ing the value of $row['id'] (BTW - you should have quotes around your array indeces) right before the setcookie() call to make sure it has a valid value?

Also, just to make sure... you are replacing "domain.com" with the actual domain name of your website, right?

Is display_errors set to On and error_reporting set to E_ALL (or integer 2047)?

Lastly, is there any chance we can get an URL to this page?

Hi,

The thing is, the cookie works on all the pages in the folder which it is set, but none outside of that. When I turned error reporting on, I got this:

Notice: Use of undefined constant userid - assumed 'userid' in /home/site/public_html/includes/top.php on line 3

Notice: Undefined index: userid in /home/site/public_html/includes/top.php on line 3

Know what could be wrong?

Thanks,
Mike

Can you show us line 3 of top.php ?

Also, again - is there any way you can give us an URL to this script?

webmasternovis

My code is simple on top.php really:

echo $_COOKIE[userid];

As for URL, one that's affected is http://www.plasticeconomy.com/about.php...

Thanks,

Array indeces in your case should be strings. $row[name] does not have a string as an index, but a constant. PHP will detect this (assuming there actually isn't a constant named 'name') and throw an E_WARNING and then assume it is a string. So, use quotes: $row['name'].

Try doing a print_r($_COOKIE); on that page to see if any cookies are showing up.

Also... is there any chance you can make a dummy login for us to test? If you don't want the world to have that information, you can PM me a user/pass to test and I'll see how the cookies are being set.

I've looked at the site, and... I'm quite perplexed. The cookie is indeed set correctly, as my browser sent the "userid=x" cookie back to the about.php after logging in.

You've got me stumped.

webmasternovis

Heh, how strange. Is there a server setting that could be forcing this error?
