我尝试构建一个应该显示在自定义 block 中的自定义注册表单,我不想插入普通注册表单并通过钩子(Hook)更改它或使用像 form_block 这样的扩展,因为我想了解如何使用 drupal 8 与表格一起工作。
我的 block 看起来像这样:
<?php
namespace Drupal\ajax_registration_form\Plugin\Block;
use Drupal\ajax_registration_form\Form\AjaxRegistrationForm;
use Drupal\Core\Block\BlockBase;
/**
* Provides a 'AjaxRegistrationBlock' block.
*
* @Block(
* id = "ajax_registration_block",
* admin_label = @Translation("Ajax registration block"),
* )
*/
class AjaxRegistrationBlock extends BlockBase {
/**
* {@inheritdoc}
*/
public function build() {
$content = \Drupal::formBuilder()->getForm(AjaxRegistrationForm::class);
return $content;
}
}
我的自定义注册表如下所示:
<?php
namespace Drupal\ajax_registration_form\Form;
use Drupal\Core\Form\FormStateInterface;
use Drupal\user\RegisterForm;
class AjaxRegistrationForm extends RegisterForm {
/**
* {@inheritdoc}
*/
public function form(array $form, FormStateInterface $form_state) {
return parent::form($form, $form_state);
}
}
我只是试图扩展正常的
RegisterForm
在第一步中,我只想返回父表单以查看它是否有效。但它不...错误信息:
Fatal error: Call to a member function getEntityTypeId() on null in /Users/*******/Sites/priv/radweiser/web/core/lib/Drupal/Core/Entity/EntityForm.php on line 77
我认为这是表单中缺少的用户实体,但我不知道如何将这个实体“放入”我的表单中。
最佳答案
我在 formblock 的代码中找到了解决方案模块。
我把我的 block 改成这样:
<?php
namespace Drupal\ajax_registration_form\Plugin\Block;
use Drupal\Core\Annotation\Translation;
use Drupal\Core\Block\Annotation\Block;
use Drupal\Core\Block\BlockBase;
use Drupal\Core\Entity\EntityFormBuilderInterface;
use Drupal\Core\Entity\EntityManagerInterface;
use Drupal\Core\Plugin\ContainerFactoryPluginInterface;
use Drupal\Core\Session\AccountInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
/**
* Provides a 'AjaxRegistrationBlock' block.
*
* @Block(
* id = "ajax_registration_block",
* admin_label = @Translation("Ajax registration block"),
* )
*/
class AjaxRegistrationBlock extends BlockBase implements ContainerFactoryPluginInterface {
/**
* The entity manager
*
* @var \Drupal\Core\Entity\EntityManagerInterface.
*/
protected $entityManager;
/**
* The entity form builder
*
* @var \Drupal\Core\Entity\EntityManagerInterface.
*/
protected $entityFormBuilder;
/**
* Constructs a new UserRegisterBlock plugin
*
* @param array $configuration
* A configuration array containing information about the plugin instance.
* @param string $plugin_id
* The plugin_id for the plugin instance.
* @param mixed $plugin_definition
* The plugin implementation definition.
* @param \Drupal\Core\Entity\EntityManagerInterface $entityManager
* The entity manager.
* @param \Drupal\Core\Entity\EntityFormBuilderInterface $entityFormBuilder
* The entity form builder.
*/
public function __construct(array $configuration, $plugin_id, $plugin_definition, EntityManagerInterface $entityManager, EntityFormBuilderInterface $entityFormBuilder) {
parent::__construct($configuration, $plugin_id, $plugin_definition);
$this->entityManager = $entityManager;
$this->entityFormBuilder = $entityFormBuilder;
}
/**
* @inheritdoc
*/
public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition) {
return new static(
$configuration,
$plugin_id,
$plugin_definition,
$container->get('entity.manager'),
$container->get('entity.form_builder')
);
}
/**
* Implements \Drupal\block\BlockBase::build().
*/
public function build() {
$build = array();
$account = $this->entityManager->getStorage('user') ->create(array());
$build['form'] = $this->entityFormBuilder->getForm($account, 'register');
$build['form']['account']['mail']['#description'] = t('');
kint($build['form']['account']);
return $build;
}
/**
*Implements \Drupal\block\BlockBase::blockAccess().
*
* @param \Drupal\Core\Session\AccountInterface $account
*
* @return bool|\Drupal\Core\Access\AccessResult
*/
public function blockAccess(AccountInterface $account) {
return ($account->isAnonymous()) && (\Drupal::config('user.settings')->get('register') != USER_REGISTER_ADMINISTRATORS_ONLY);
}
}
现在我可以使用 Form Api 更改表单并实现 ajax 逻辑(例如更改邮件输入描述)
