Setting and Retrieving cookies

Anon

Cookies driving me nuts! I spent the entire weekend reading setCookie() on php.net and searching/browsing this forums.

setting cookies isn't a problem, it didn't retreive anything, so I browse some more, got it to retreive and now it will not set a new cookies. The first cookies set is permanent! Setting a new value for the same cookies will not update it. Is this a browser bug? Anyway here is the code I use:

// Cookies information
$cookie_life = 30243600;
$c_name = "themes"; // cookies name

if ($QUERY_STRING == "themes")
{
// Set cookies and continue
setcookie($c_name,$themes,(time()+$cookie_life),'/','',0);
$$c_name = $themes;
Header("Location: /");
}

$someValue = $HTTP_COOKIE_VARS[$c_name];
if (isset($someValue)) {
echo "got cookies: $someValue";
}
else { // $someValue is neither set

}

after selecting a theme for the first time, selecting another theme will not update the cookies.

cookies.txt

www.mydomain.ca FALSE / FALSE 989893234 themes red

When you retrive the cookie, try this:

$someValue = $HTTP_COOKIE_VARS["c_name"];

That should work for you.

But "c_name" is not what was stored. "$c_name" is a string variable storing the name of the cookies.

When HTTP_COOKIES_VARS hash for the cookies, it will hash for the value of $c_name (themes) not c_name.

$c_name = "themes";

$HTTP_COOKIES_VARS[$c_name] is the same as saying $HTTP_COOKIES_VARS["themes"]

$HTTP_COOKIES_VARS[c_name] wouldn't exist, would it?

OK, I took your code and tested it can came up with this:

// Cookies information
$cookie_life = 30243600;
$c_name = "themes"; // cookies name

if ($QUERY_STRING == "themes")
{
// Set cookies and continue
setcookie($c_name,$themes,(time()+$cookie_life),'/','.mydomain.ca ',0);
$$c_name = $themes;
Header("Location: /");
}

$someValue = $HTTP_COOKIE_VARS["$c_name"];
if (isset($someValue)) {
echo "got cookies: $someValue";
}
else { // $someValue is neither set
echo "didn't find the cookie";
}

It works for me, hope it does for you!

That is so strange...it works now. Any idea why? beside the '.mydomain.ca' in the setcookie parameter?

Thanks for your help!

Yeah that was it, you have to have a domain in the cookie so it knows where to apply the cookie. If there is anything else you need, let me know!
