membangun pada jawaban oleh Charlie, saya menemukan bahwa dibutuhkan jumlah waktu yang sama untuk memuat ulang blok jika Anda menambahkan 1 atau 100 item, jadi di sini adalah trik untuk menambahkan daftar pilih angka dalam bentuk di sebelah 'tambah lebih banyak sehingga Anda dapat memilih berapa banyak yang Anda tambahkan. Ini menghemat banyak waktu dan masih fleksibel. Bisa dibungkus dengan modul kecil
<?php
/**

function village_field_attach_form($entity_type, $entity, &$form, &$form_state, $langcode){
$options = array('language' => field_valid_language($langcode));
// Merge default options.
$default_options = array(
'default' => FALSE,
'deleted' => FALSE,
'language' => NULL,
);
$options += $default_options;
list(, , $bundle) = entity_extract_ids($entity_type, $entity);
$instances = _field_invoke_get_instances($entity_type, $bundle, $options);
// Iterate through the instances.
$return = array();
foreach ($instances as $instance) {
// field_info_field() is not available for deleted fields, so use
// field_info_field_by_id().
$field = field_info_field_by_id($instance['field_id']);
$field_name = $field['field_name'];
//If we are looking at our field type and specific widget type, and we are multiple entries
if($field['cardinality'] == FIELD_CARDINALITY_UNLIMITED){
//Check just in case the button is here, and add another #submit function

Saya juga memposting saran di Drupal.org di https://drupal.org/node/1394184#comment-8252701 di
mana op memiliki masalah yang sama.
