Unexpected behaviour of cookie

[gdebojyoti.mail96]

My login verify script -

if($pass == $hash)
setcookie("cookiename",$cookieVal);

This stores the cookie in the broswer. No problems with this; I have checked it myself.

However in a different page when I check to see if the cookie exists, it returns false.

if(isSet($_COOKIE['cookiename'])) echo "Cookie is set";
else echo "Not set";

The above code prints "Not set" in the broswer window.

Also, if I try

echo $_COOKIE['cookiename'];

the ouput is an error Notice: Undefined index: cookiename

Apparently the browser (Firefox) cannot identify the cookie, although I can see it present when I check my broswer's options tab! Later, I also tried in Chrome and IE - same issue.

What am I doing wrong?


Update: When I added

if(isSet($_COOKIE['cookiename'])) echo "Set";

to the end of the login verify script, my cookie was detected ("Set" was printed)! But it isn't being detected in any other page.

Okay, problem solved. I was missing the path parameter. The code should be one of the following -

setcookie("cookiename",$cookieVal,0,'/');

setcookie("cookiename",$cookieVal,time()+60*60*24*365,'/');
