cookie headache

[remote2]

before i thought that cookie existed in the same site can be accessed anywhere in the site...

I discovered that cookie doesnt work if you work outside the directory where the cookie is set.

for the cookie 'user_id' i set it in a login page under a login directory

all the pages requires to look at this user_id cookie
if i do $COOKIE['user_id'] is the login directory is ok..
but outside that directory $COOKIE['user_id'] is blank..

is there a way of reading cookie i set in the login directory?

Look at all the parameters that setcookie() takes:

You'll be using the path argument to solve this problem.

in order to use a cookie at all locations in your site you need to set the path argument to "/".
I.E. setcookie("cookiename",$value,$cookie_expiry,"/");
