well, you could simply loop through the session vars and build the query as you go.
$query = "SELECT * FROM Inventory WHERE"; // I'm assuming you keep your item numbers in a "items" or something similar foreach ($HTTP_SESSION_VARS['items'] as $pid) $subquery .= " ItemNumber = '$pid' OR "; // get rid of last _OR_ $subquery = ereg_replace('[:space:]OR[:space:]$', '', $subquery); // put the query together $query = $query . $subquery; // add more crap to query if you want $query .= " and some_other_column='something_else'"; Jim Grill Support Web-1 Hosting http://www.web-1hosting.net ----- Original Message ----- From: "Anup" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, July 25, 2002 1:51 PM Subject: [PHP] mySQL Queries using PHP's SESSION variables > Hello, I am stuck here.
