I am new to drupal 8 and assisting my development team with design part. We are stuck in one place and not manage to move forward. We want to pass the node ID info to a webform filed which exist in another page. In the attached image I have explained what we want to achieve in Drupal 8 Environment, previously with PHP hack it was possible in drupal 7 but no idea how to achieve the same in drupal 8.

Assuming you want: The user will create a node. Upon submission a form will be displayed showing the node id pre-filled in a form. Make a module called example:

// example.module:
// we created a node type "product" (using UI). Saving this content
// will trigger the product form
 * Implements hook_ENTITY_TYPE_insert().
 * @param \Drupal\node\NodeInterface
function example_node_insert(NodeInterface $node) {
  if ($node->bundle() == 'product') {
    $nid = $node->id();
    $response = new \Symfony\Component\HttpFoundation\RedirectResponse(\Drupal\Core\Url::
    fromRoute('product.form', ['nid' => $nid])->toString());
    $response->send(); // When OO we will return the response object instead

// example.routing.yml
  path: '/form/product/{nid}'
    _form: '\Drupal\example\Form\ProductForm'
    _title: 'Product Form'
    _permission: 'access content'

// src/Form/ProductForm

namespace Drupal\example\Form;

use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormStateInterface;
use Drupal\node\NodeInterface;

class ProductForm extends FormBase {

   * @var NodeInterface
  protected $node;

  public function getFormId() {
    return 'example_product_form';

  public function buildForm(array $form, FormStateInterface $form_state, $nid = null) {
    // if you need to load the node
    // $this->node = NodeInterface::load($nid);

    $form['node_id'] = [
      '#type' => 'textfield',
      '#title' => 'Node ID',
      '#value' => $nid,

    return $form;

  public function submitForm(array &$form, FormStateInterface $form_state) {
    // TODO: Implement submitForm() method.
    // you can redirect back to the node


When dealing with this issue please realize the node id is not available until you save the node.


Webform 8.x-5.x allows elements to be populated using query string parameters but you must enable this feature.

Another approach would be to set the element's default value to a [current-page:query:?] token like [current-page:query:nid]

  • Hi, Thank you for your comments. Actually my form is located in different URL; I need to catch current page title and pass this to my webform which is located in different URL. With your method it is getting the title of my webform page; I want my product page title to be passed in my webform. – user1551692 Mar 28 '17 at 9:31
  • In short, I want to populate my referral page title in my current webform input box. – user1551692 Mar 28 '17 at 9:47

Trying using the [webform_submission:node:title] within the confirmation redirect URL's querystring parameter.

BTW, you must use an absolute URL. I just found this bug and created a issue on D.O. https://www.drupal.org/node/2864996
