Tengo las siguientes rutas en module_name.routing.yml.
module_name.usergroup_delete:
path: 'module_name/usergroup/delete/{arg1}'
defaults:
_form: '\Drupal\module_name\Form\DeleteUserGroup'
_title: 'Delete User group'
requirements:
_permission: 'access admin menus'
Este es el código en module_name / src / Form / DeleteUserGroup.php.
namespace Drupal\module_name\Form;
use Drupal\Core\Form\ConfigFormBase;
use Drupal\Core\Form\FormStateInterface;
class DeleteUserGroup extends ConfigFormBase {
public function getFormId() {
return 'delete_user_group';
}
/**
* General form for switching all nodes from one user to another.
*/
public function buildForm(array $form, FormStateInterface $form_state,$product_code) {
$form['_product'] = array(
'#type' => 'value',
'#value' => $product_code,);
//get the user group and username to display the confirmation message
$result = db_query('select field_p_group_name_value from {content_type_usergroup} ctu'
. ' where vid=%d',$product_code);
while ($row = $result->fetchObject()) {
$user_group = $row->field_p_group_name_value;
}
return confirm_form($form,t('Are you sure you want to delete "' .$user_group. '" User Group?'),
isset($_GET['destination']) ? $_GET['destination'] : "function_name",t('This action cannot be undone.'),t('Delete'),t('Cancel'));
}
/**
* #submit callback for node_adoption_transfer_form().
*/
public function submitForm(array &$form, FormStateInterface $form_state) {
$form_values = $form_state->getValues();
//if ($form_state['values']['confirm']) {
$param = $form_state->getValue('_product');
drupal_set_message(t('Group ' .$param.' will get deleted.'));
db_query('DELETE FROM {content_type_usergroup} WHERE vid = %d', $param);
//delete the users of the usergroup too
db_query('DELETE FROM {usergroup_user_map} WHERE group_id=%d', $param);
drupal_set_message(t('usergroup has been deleted.'));
drupal_goto('function_name');
}
protected function getEditableConfigNames() {
return "delete_user_group";
}
}
Estoy teniendo el siguiente error:
DeleteUserGroup :: buildForm () debe ser compatible con Drupal \ Core \ Form \ FormInterface :: buildForm (array $ form, Drupal \ Core \ Form \ FormStateInterface $ form_state)
¿Por qué?
¿Alguien puede explicar cómo se compara esto al usar el módulo WebForm? No tengo ningún módulo específicamente para el formulario que he creado usando el módulo, entonces, ¿cuál sería el punto '_form' dentro del archivo routing.yml?
