Your query should probably be performing a join. As it stands you're
selecting all of the products where userID = $userID, but you're also
selecting all of your users regardless (SELECT blah FROM users).
What relationship does the Users table have to the Products table? You
may need something more along the lines of:
SELECT blah FROM products LEFT JOIN users ON users.UserID =
products.UserID WHERE users.UserID = $userID
But that's just a best-guess based on what you've given so far.
Best regards,
Richard Davey
