Check before inserting in DB ???

Posted on 16th Feb 2014 07:03 pm by admin

This is my code
---------------
if ( $_POST ['Submit'])
{{
$username = $_POST ['usernm'];
$userpassword = $_POST ['userpw'];
}
/*insert data from the form into the db table*/

$querypost = mysql_query ("INSERT INTO users (usernm, userpw) VALUES ('$username','$userpassword')");
}
?>

How do I check before inserting whether that username and password is already inserted. I have an id assigned to every entry.
