I am building a D8 module that, for configuration, needs a list of webforms and their fields (just the entity reference fields, but I am not picky)

I can get the webforms with this:

  $webforms = \Drupal::entityTypeManager()->getStorage('webform')->loadMultiple(null);

But once I get the returned elements (Drupal\webform\Entity\Webform::__set_state), how can I fetch the elements in the webform referenced?

  • Are you trying to get the values a user entered? or just the field names the form contains? – No Sssweat Apr 20 '19 at 12:20
  • Thanks, I was looking for the form's field names, and found the result myself.... eventually. Posted below. – Michael D. Moradzadeh Apr 21 '19 at 16:52

By trawling through the code, I found this handy function in the Entity code, and it works perfectly:

 $elements = $webform->getElementsDecodedAndFlattened();

This gives a nice array of the elements in the webform itself.

If you want the results of a submission, grab that entity and use:

$data = $entity->getData();

I hope this helps
