根据查理(Charlie)的答案,我发现如果要添加1或100个项目,则重新加载块所需的时间大约相同,因此,这是一个技巧,可以在“添加”旁边的表格中添加数字选择列表更多”,因此您可以选择要添加的数量。这样可以节省大量时间,并且仍然很灵活。可以包装到一个小模块中
<?php
/**
* Implements hook_field_attach_form()
*/
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
if(isset($form[$field['field_name']]['und']['add_more'])){
// add a simple select list, this defaults to numb 3
$form[$field['field_name']]['add_more_number'] = array(
'#type' => 'select',
'#title' => t('Add more no.'),
'#options' => drupal_map_assoc(range(0, 50)),
'#default_value' => 2,
);
$form[$field['field_name']]['und']['add_more']['#submit'][] = 'village_field_add_more_submit';
$form[$field['field_name']]['und']['add_more']['#value'] = 'Add more rows';
}
}
}
}
function village_field_add_more_submit($form, &$form_state){
$button = $form_state['triggering_element'];
// Go one level up in the form, to the widgets container.
$element = drupal_array_get_nested_value($form, array_slice($button['#array_parents'], 0, -1));
$field_name = $element['#field_name'];
$langcode = $element['#language'];
$parents = $element['#field_parents'];
// Alter the number of widgets to show. items_count = 0 means 1.
$field_state = field_form_get_state($parents, $field_name, $langcode, $form_state);
//get the number from the select
$numbtoadd = $form[$field_name]['add_more_number']['#value'];
if($numbtoadd){
$field_state['items_count'] += $numbtoadd;
field_form_set_state($parents, $field_name, $langcode, $form_state, $field_state);
$form_state['rebuild'] = TRUE;
}
}
?>
我还在https://drupal.org/node/1394184#comment-8252701上的Drupal.org上发布了该建议,
其中操作存在类似问题。
