help with the cookie

[jangkoo]

Hi friends,
I have problem with cookie
in one file a.php I did this:

setcookie("user",$_POST['username']);

then I redirect to another file b.php
try to

echo $_COOKIE["user"];

and it says something like no index "user"
but when I browse to a.php, and
echo $_COOKIE["user"];
it can print the correct one.
So what is wrong with the b.php, anything wrong or?
could you all help me.
thanks in advance

You need to set the third parameter of the set_cookie() for the time the cookie should exist.

thanks for replying, I tried:

setcookie("user",$_POST['username'],time()+60*60*24*30);
but the problem is still on
The problem is that :
When I browse to a.php or c.php in the same folder with a.php, I can prrint $_Cookie['user']
but when I navigate to b.php in other folder, I echo $_Cookie['user'] , it produce this :

Notice: Undefined index: user in D:\xampp\htdocs\gui\createGUI.php on line 290
I know that it's because the cookie['user'] is not set, but after that I go back to a.php, I can print it out, that means it's set.
So what 's wrong?
any problem may be?

You're skipping the $path parameter in setcookie() (http://php.net/setcookie). (read up!)

The default value is the directory where the script is located (e.g., if you set a cookie in a script in /some/dir, it will be available in /some/dir or /some/dir/example, but not in /some or /some/other).

Using / will make the cookie available to the whole domain.

tangent (re: w3schools):

the information at w3schools is misleading, incomplete, inaccurate, and/or flat wrong in many instances.
there are other, far better, resources for web development:
html,css,javascript from the ground up (http://code.google.com/edu/submissions/html-css-javascript/) is a fantastic introductory tutorial series.
sitepoint (http://reference.sitepoint.com/) is a through, straightforward reference site
the MDN (https://developer.mozilla.org) is great for intermediate/advanced topics
I find quirksmode (http://www.quirksmode.org/) very useful in figuring out problems (it's not always completely up-to-date, but the info it provides is solid)
the W3C (http://www.w3.org/community/webed/wiki/Main_Page) is not really aimed at beginners, but they are the standards body - w3schools is not affiliated with the w3c in any way.

Thanks traq very much, it works as your method, thanks :D
I thought if we don't put the 'path', it will be set to whole domain by default.
