To load the login form I am using the following code.

$form = \Drupal::formBuilder()->getForm('Drupal\user\Form\UserLoginForm');

I would like to load the form to create or edit a node. How can I achieve this?


Copying partially from an answer that I gave here: How to alter $form_state before render a form?

To get an add form, you can have to do something like this:

$values = array('type' => $node_type);

$node = \Drupal::entityTypeManager()

$form = \Drupal::entityTypeManager()
  ->getFormObject('node', 'default')
return \Drupal::formBuilder()->getForm($form);

Edit: Somehow I missed that you said edit. You do exactly the same then, except that you don't create a new $node, you load the one you want to edit and then use that.

As written there, this is based on the entityblock_form module, so if you need this in a block, you can also just use that module.

    If you are in a controller, there's an easier way to get the node add form. After creating the new node object as in Berdir's code above, you can simply use: $form_render_array = $this->entityFormBuilder()->getForm($node); – Giles B Oct 22 '17 at 21:38
  • Awesome hint, kudos to Berdir – Stefan Korn Nov 21 '17 at 17:25
