$query = $dou->select($dou->table('download'), '*', '`id` = \'' . $id . '\'');
$download = $dou->fetch_array($query);
$download['image'] = $download['image'] ? ROOT_URL . $download['image'] : '';

download.dwt數(shù)據(jù)無法調(diào)用，最新版，需要將download.php上面的替換為

$download = $dou->get_row('download', '*', "id = '$id'");
$download['image'] = $dou->dou_file($download['image']);
