Re: mysql_num_rows(): supplied argument is not a valid MySQL result

[Peter Brawley]

Change the func to something like ...

function runQuery($query) {
  $connect = mysql_connect(MYSQL_SERVER, MYSQL_USERNAME, MYSQL_PASSWORD)
             or exit( "<div class=\"error\">" . mysql_error() . "</div>" );
  mysql_select_db(MYSQL_DATABASE, $connect)
    or exit( "<div class=\"error\">" . mysql_error() . "</div>" );
  $result = mysql_query($query, $connect);
            or exit( "<div class=\"error\">" . mysql_error() . "</div>" );
  return $result;
}

And once you have that working, consider improving it by changing the exit() calls to invoke an error handling function that logs errors to an error file.
