PHP database connection failed

[ducsync]

I have a php file that includes two functions, one to connect to the database and one to set cookied for the cart. Here is that file:\[code\]<?php$dbServer="localhost";$dbName="test";function ConnectToDb($server, $database){ $s=@mysql_connect($server); $d=@mysql_select_db($database, $s); if(!$s || !$d) return false; else return true;}function GetCartId(){ if(isset($_COOKIE["cartId"])){ return $_COOKIE["cartId"];}else { session_start(); setcookie("cartId", session_id(), time()+((3600*24)*30)); return session_id();}}?>\[/code\]The function for connecting to the database works well in another php file for this particular program. I am having a problem with it in this file:\[code\]<?phpinclude("db.php"); switch($_GET["action"]) { case "add_item": { AddItem($_GET["id"], $_GET["qty"]); ShowCart(); break; } case "update_item": { UpdateItem($_GET["id"], $_GET["qty"]); ShowCart(); break; } case "remove_item": { RemoveItem($_GET["id"]); ShowCart(); break; } default: { ShowCart(); } } function AddItem($itemId, $qty) { // Will check whether or not this item // already exists in the cart table. // If it does, the UpdateItem function // will be called instead $cxn = @ConnectToDb($dbServer, $dbName); // Check if this item already exists in the users cart table $result = mysql_query("select count(*) from cs368_cart where cookieID = '" . GetCartID() . "' and itemId = $itemId"); $row = mysql_fetch_row($result); $numRows = $row[0]; if($numRows == 0) { // This item doesn't exist in the users cart, // we will add it with an insert query @mysql_query("insert into cs368_cart(cookieID, itemId, qty) values('" . GetCartID() . "', $itemId, $qty)"); } else { // This item already exists in the users cart, // we will update it instead UpdateItem($itemId, $qty); } } function UpdateItem($itemId, $qty) { // Updates the quantity of an item in the users cart. // If the qutnaity is zero, then RemoveItem will be // called instead $cxn = @ConnectToDb($dbServer, $dbName); if($qty == 0) { // Remove the item from the users cart RemoveItem($itemId); } else { mysql_query("update cs368_cart set qty = $qty where cookieID = '" . GetCartID() . "' and itemId = $itemId"); } } function RemoveItem($itemId) { // Uses an SQL delete statement to remove an item from // the users cart $cxn = @ConnectToDb($dbServer, $dbName); mysql_query("delete from cs368_cart where cookieID = '" . GetCartID() . "' and itemId = $itemId"); } function ShowCart() { // Gets each item from the cart table and display them in // a tabulated format, as well as a final total for the cart $cxn = @ConnectToDb($dbServer, $dbName); $result = mysql_query("select * from cs368_cart inner join cs368_products on cart.itemId = items.itemId where cart.cookieID = '" . GetCartID() . "' order by items.itemName asc") or die("Query to get test in function ShowCart failed with error: ".mysql_error());?>\[/code\]What can I do the remedy this problem? Thanks!
