Thingee

Alright I got it figured out. I don't know why but when I first wrote the code I used the following... [code] if(!isset($_SESSION["cart"])){ $_SESSION["CART"] = NULL; } [/code] I just changed null to array(); and that fixed the problem :). Thanks for everyone's help!

The code works on localserver. Items get added correctly without any errors. I do have all the error reports turned on too on my localserver. Now the other server is on a certain hosting company so I can't make changes to their php.ini file =/. Sorry about the little info I gave. The file that adds items to the cart and uses the function above is manage.php. So the url looks like this... manage.php?act=add&pid=X. Manage.php looks like this... [code] <?php if (isset($_GET["act"])) {     if ($_GET["act"] == "add") // add item     {         //unserialize($_SESSION["cart"]);         if (!isset($_SESSION["cart"]))         {             // add first item             $cart->add_item_to_cart($_GET["pid"],1);         }         else if (array_key_exists($_GET["pid"], $_SESSION["cart"]))         {             // add 1 to quantity if item in cart already             $cart->add_item_to_cart($_GET["pid"],++$_SESSION["cart"][$_GET["pid"]][1]);         }         else         {             // add any other items after first item             $cart->add_item_to_cart($_GET["pid"],1);         }     }     elseif ($_GET["act"] == "del") // delete item     {         $cart->del_item($_GET["pid"]);         } } ?> [/code] Here is the full function for adding an item to the cart... [code] <?php function add_item_to_cart($id, $quantity)     {         // set cookie and store value in session         $this->setstp();             db_connect();         $sel_products = mysql_query("SELECT special_pick, special, price, artist, album FROM products WHERE id=".$id."");         $item = mysql_fetch_array($sel_products);         // returns the number of rows in a result, if 1 item exists if 0 item doesn't exists.         $num_rows = mysql_num_rows($sel_products);         // if item exists then add item to cart         if ($num_rows >= 1)         {             session_regenerate_id(TRUE);                  $_SESSION["cart"][$id][0] = $id;             $_SESSION["cart"][$id][1] = $quantity;                          $_SESSION["cart"][$id][2] = $item['$special_pick] != 0 ? 'y' : 'n';             $_SESSION["cart"][$id][3] = $item['special_pick'];             $_SESSION["cart"][$id][4] = $item['special'] == '0.00' ? '0.00' : $item['special'];             $_SESSION["cart"][$id][5] = $item['price'];             $_SESSION["cart"][$id][6] = $item['artist'];             $_SESSION["cart"][$id][7] = $item['album'];         header ("location:".$_SERVER['HTTP_REFERER']);                      }     } ?> [/code] Thanks for helping me :).

[/quote] True. The server not having problems is a slackware box that I'm running at my house. The one having trouble is an actual hosted server with some company. Is there any information you would need to know in order to really know why I'm having this error?

I'm writing a simple cart script right now and for some reason when I moved it to another server I got these errors when I try to add an item to the cart...

So right now it currently does not add anything on the cart. Any ideas?
