我如何生成一个表单，知道它的ID？

Question

使用Drupal 8，我想使用注册表单外部用户/注册。

我可以生成用户登录表单，但是我找不到如何获取user.register表单。

因此，我的问题是，我如何呈现用户登记表？

Answer 1

用户注册表单位于Drupal\user\RegisterForm中。检查User类上的注释。

/**
 * Defines the user entity class.
 *
 * The base table name here is plural, despite Drupal table naming standards,
 * because "user" is a reserved word in many databases.
 *
 * @ContentEntityType(
 *   id = "user",
 *   label = @Translation("User"),
 *   handlers = {
 *     "storage" = "Drupal\user\UserStorage",
 *     "storage_schema" = "Drupal\user\UserStorageSchema",
 *     "access" = "Drupal\user\UserAccessControlHandler",
 *     "list_builder" = "Drupal\user\UserListBuilder",
 *     "views_data" = "Drupal\user\UserViewsData",
 *     "route_provider" = {
 *       "html" = "Drupal\user\Entity\UserRouteProvider",
 *     },
 *     "form" = {
 *       "default" = "Drupal\user\ProfileForm",
 *       "cancel" = "Drupal\user\Form\UserCancelForm",
 *       "register" = "Drupal\user\RegisterForm"
 *     },
 *     "translation" = "Drupal\user\ProfileTranslationHandler"
 *   },
 *   admin_permission = "administer users",
 *   base_table = "users",
 *   data_table = "users_field_data",
 *   label_callback = "user_format_name",
 *   translatable = TRUE,
 *   entity_keys = {
 *     "id" = "uid",
 *     "langcode" = "langcode",
 *     "uuid" = "uuid"
 *   },
 *   links = {
 *     "canonical" = "/user/{user}",
 *     "edit-form" = "/user/{user}/edit",
 *     "cancel-form" = "/user/{user}/cancel",
 *     "collection" = "/admin/people",
 *   },
 *   field_ui_base_route = "entity.user.admin_form",
 *   common_reference_target = TRUE
 * )
 */

_entity_form: user.register从这里来。
