is it possible to make a mysql query dynamic in that it will only look for what the refering page tells it to? i imagine it should, but i can't get it to work.
submitted for your approval:

$clientLogin is a single textbox that is passed to clientLogin.php via index.php and is then broken into two parts. i havn't really tested this part yet, but to the untrained eye it looks like it'd work fine. the problem is how below in the query i want to dynamically insert the info passed to this page. to test i have two entries in my database, and if i manually put in my search criteria it will work fine, but that's as far as i've gotten.

PHP Code:
// login info broken down into useful chunks, the user and their domain
$clientLogin strtolower($clientLogin);
$clientLoginArray explode("."$clientLogin);
$clientLoginArray[0] = $clientUser;
$clientDomain $clientLoginArray[1] . $clientLoginArray[2];
$clientUser trim($clientUser);
$clientDomain trim($clientDomain);

// database connetion variables
$host "localhost";
$user "root";
// $password = "";
$dbName "clientData";
$dbTable "clientInfo";

$link mysql_connect ($host$user$password);
$query "SELECT * from $dbTable WHERE user = '$clientUser' AND domain = '$clientDomain'";
$result mysql_db_query($dbName$query$link);

while (
$row mysql_fetch_array($result)) {
mysql_close ($link
i'm really quite new at both php and sql so i appologize for being thick, but i'm usually pretty good at figuring this kind of thing out.
