The cookie is set here: http://wouldyouratherquestions.net/include/click.php?id=1

an will also display there on the second reload, but the strange part is wont work on any ny other page on the site. I call the cookie an it's vanished but go back to that page an refresh an still is set anyone know what the problem is?

 
$id = $_GET['id']; 
 $value = '2';
setcookie($id,$value, time()+3600*336,'/');
echo $_COOKIE[$id];

PHP:

This is the code for the above page.


This is the code on home page I'm calling the cookie an doesn't work.

 
$id = $row['id'];
echo $_COOKIE[$id];

PHP:

Will not work on any page but that one page above weirdest thing ever.

Please help tried a lot of solutions.

 

Try this:

$domain = '.example.com';

setcookie($id,$value, time()+3600*336,'/', $domain);

PHP:

Also use your browser to view cookies and see when they're loaded and if they are removed too quickly.

 

That wasn't the problem an already tried that too btw. I already fixed it myself anyways.
