Firefox only cookie problem

chapsymphony

I've tested this in Firefox 1.0, IE 6, Opera 7+ and Safari 1.2. Firefox is the only browser in which this error occurs.

I'm setting a cookie with php and it's not showing up the the $_COOKIE array in Firefox for some reason. This code is excecuted every time:

if (!$_COOKIE['sub_domain_com']) {
    // Set the cookie
    setcookie('sub_domain_com', 'variables go here', time() + 2592000, '/'); // 30 days
}

I check Firefox's cookie cache and there it is, just as it should be. I don't want to reset this cookie every time. Is this a bug or am I doing something wrong?

im guessing your trying to make a cookie work across multiple subdomains

http://example.org
http://www.example.org
http://sub.example.org

if thats the case, you need to set the domain parameter of setcookie() approriately


setcookie('name', 'val', time() + 2592000, '/', '.example.org');

notice i put a . in front of example.org

doing that tells the browser to send the cookie for not only example.org, but also to all subdomains of example.org

and yes, www IS a subdomain

Thanks for the prompt reply rehfeld. I would have wanted the cookie available across multiple subdomains at some point, so your post was helpful in that regard. However, I tested it and my original problem still remains.

have you changed firefox's cookie settings? maybe made them more strict?
although, if you did, i would imagine it wouldnt even accept the cookie, but you say it is, its just not sending the cookie back.

maybe your using some characters in either the name or value, that firefox doesnt like for some reason.

have you tried just setting a simple dummy cookie? like

setcookie('foo', bar');

I haven't changed Firefox's cookie settings at all. The cookie is being accepted, I can see it in the cookie manager. I was using a serialized array for the value, but now i'm just using an integer. Same result.

print_r(apache_request_headers());

to see if firefox is sending the cookie, and maybe php isnt parsing it for some reason.

You can also install the livehttpheaders extension and have a look at what headers are in the requests Firefox is sending out and the responses it is receiving. (PS: If I recall Firefox's default settings, it will only accept cookies if the domain it refers to is the same as the one that it is coming from. This is the case I take it, however?)
