this seems pretty easy one, loop on loop so...

$limit = 5;  ($i = 1; $i <= $limit; $i++) {     $builder         ->add('file_'.$i, 'file', array(             'required'  => false,              'label'     => 'file '.$i,         ))         ->add('filename_'.$i, 'text',  array(             'required'  => false,             'label'     => 'subject '.$i,         ))         ->add('description_'.$i, 'text', array(             'required'  => false,              'label'     => 'description '.$i,         ))     ; }
