Hi,

May i know whats wrong with my code.. when i display the products.php page.. these error shown...
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/eonenet/public_html/shopping_cart/products.php on line 24
* this is not the first time i encountered this..

i've checked my code and it should not have any prob coz i did assign a value for result variable,, but why i can't view the page.. did i miss something ???

please advise.


my db.php file ::::
Code: 
<?

$dbserver = "";
$dbuser = "user";
$dbPass = "pass";
$dbName = "database";

function ConnectToDb($server, $user, $pass, $database)
{
	$s = @mysql_connect($server, $user, $pass);
	$d = @mysql_select_db($database, $s);

if (!$s || !$d)
	return false ; 
else
	return true ;
}



function GetCartId()
{
	//generate an encrypted string and set it as cookie
	if (isset($_cookie["cartId"]))
	{
		return $_cookie["cartId"];
	}
	else
	{
		session_start();
		setcookie("cartId", session_Id(), time() + ((3600 * 24) * 30));
		return session_id();
	}
}

?>



my products.php code:

Code: 
<?

include ("db.php");

$cxn = @ConnectToDb($dbServer, $dbUser, $dbPass, $dbName);
$result = mysql_query("select * from items order by itemName asc");

?>

I would take the @ out so you can see what errors it is producing. Check servername, usernames, passwords, spelling in the database table and other such things.
 
or use next:
Code: 
<?
$dbserver = "";
$dbuser = "user";
$dbPass = "pass";
$dbName = "database";

function ConnectToDb($server, $user, $pass, $database)
{
	$s = @mysql_connect($server, $user, $pass) or die("cannot connect to database<BR>MySQL said:" . mysql_error());
	$d = @mysql_select_db($database, $s);

if (!$s || !$d)
	return false ; 
else
	return true ;
}
 
echo mysql_error() will make life much easy... :idea: :arrow:
