drupal8表单定义的变化:
扩展基础表单类EntityFormControllerNG来自定义表单
别忘了定义位置和调用核心类库
<?php
/**
* @file
* Definition of Drupal\entity_test\EntityTestFormController.
*/
namespace Drupal\entity_test;
use Drupal\Core\Entity\EntityInterface;
use Drupal\Core\Entity\EntityFormControllerNG;
class EntityTestFormController extends EntityFormControllerNG {
public function form(array $form, array &$form_state, EntityInterface $entity) {
//--继承父表单
$form = parent::form($form, $form_state, $entity);
//--相关语言的扩展
$langcode = $this->getFormLangcode($form_state);
$translation = $entity->getTranslation($langcode);
$form['name'] = array(
'#type' => 'textfield',
'#title' => t('Name'),
'#default_value' => $translation->name->value,
'#size' => 60,
'#maxlength' => 128,
'#required' => TRUE,
'#weight' => -10,
);
$form['user_id'] = array(
'#type' => 'textfield',
'#title' => 'UID',
'#default_value' => $translation->user_id->value,
'#size' => 60,
'#maxlength' => 128,
'#required' => TRUE,
'#weight' => -10,
);
$form['langcode'] = array(
'#title' => t('Language'),
'#type' => 'language_select',
'#default_value' => $entity->language()->langcode,
'#languages' => LANGUAGE_ALL,
);
return $form;
}
}
?>
调用显示表单的方法：
<?php
/**
* Menu callback: displays the 'Add new entity_test' form.
*
* @return array
* The processed form for a new entity_test.
*
* @see entity_test_menu()
*/
function entity_test_add() {
drupal_set_title(t('Create an entity_test'));
$entity = entity_create('entity_test', array());
return entity_get_form($entity);
}
?>
