Login

I am compleatly lost here thought I was going in the right direction now I am all lost. Can someone please help me with this code. I want people to log in before posting any news or uploading files to the dtabase so I can track them.

Here is the code.

<?

// Log into the database and check the user and password
$db=mysql_connect ("localhost", "Login", "pass") or die ('I cannot connect to the database.');
mysql_select_db ("forums");
$result = mysql_query("SELECT * FROM ibf_members WHERE LOWER (name) = '$FUser' and password = '$FPassword'");
$x=0;

$qry = "SELECT * FROM ibf_members";
//$result = mysql_num_rows($qry);
$result = mysql_query($qry);
$num_rows = mysql_num_rows($result);

print $num_rows;


if (!$result)
{
$x="if (!$result)";
}
if ($num_rows = mysql_num_rows($result)>0)
{
$x="Long if";
} else
{
$x="else";
}
echo $x;
echo $number;
?>



I would also like to set a cookie. The problem is I am trying to log into an existing database and they have a cookie already set from their login. Any sugestions or help is apreciated!
