PHP cookies

[PaulStat]

Hi Guys,

I'm trying to implement cookies into my website but it doesn't seem to recognise that I've set the cookie and gives me a new one everytime.

<?php
   if(isset($_COOKIE['shoppingcart_id'])) {
      echo "COOKIE IS SET";
   }
   else {
      echo "COOKIE IS NOT SET";
      
      //generate a random 10 character code
      $shoppingcart_id = generateId();

     //get the current date
     $today = date("Y-m-d");

     //get the users ip
     $user_ip = $_SERVER['REMOTE_ADDR'];

     //set the lifetime of the cookie
     $expire = time()+(60*60*24*7);

     //set the domain for which the cookie is valid
     $dom = $_SERVER['SERVER_NAME'];
     if($dom[0] == "w"){
        //truncate the first three characters
	$domain = substr($dom, 3);
     }
     else {
        //add point
	$domain = ".".$dom;
     }

     //finally send the cookie to the user agent
     setcookie("shoppingcart_id", $shoppingcart_id, $expire, "/", $domain)
   }

It always goes via the not set route?

sorry not sure what you mean, can you give an example?

Edit: Hmm just found that If upload the same code to my webserver and run it from there it works?!?!?!

Right ok, what counts as a session though? If a user puts something in their cart, browses away from the site briefly and then comes back will the session still be valid?
