How I can create a user programatically in drupal 8. I am using the following code to generate user registration form.

$account = $this->entityTypeManager->getStorage('user')->create([]);
$form = $this->entityFormBuilder->getForm($account, 'register');

and form_sate values using the following code.

$form_state = (new FormState())->setValues(['name' => 'user1', 'pass' => 'pass']);

Now how can submit this form using the above form_state values?

I think you needn't use the registration form as you have mentioned. You can use the following code to create a new user:

if (!user_load_by_mail('email_id')) {
  $language = \Drupal::languageManager()->getCurrentLanguage()->getId();
  $user = \Drupal\user\Entity\User::create();

  //Mandatory settings
  $user->setPassword('your_password');
  $user->enforceIsNew();
  $user->setEmail('email_id');
  $user->setUsername('user_name'); //This username must be unique and accepts only a-Z,0-9, - _ @ .

  //Optional settings
  $user->set("init", 'email');
  $user->set("langcode", $language);
  $user->set("preferred_langcode", $language);
  $user->set("preferred_admin_langcode", $language);
  //$user->set("setting_name", 'setting_value');
  $user->activate();

  //Save user
  $result = $user->save();
}

You can ensure that an user with same email id doesn't exist using user_load_by_mail(), and then proceed with the user creation.

  • Thanks for the answer, here how I can get an error message if a user exist with same email Id in database? – Unnikrishnan Aug 29 '16 at 7:57
  • I'm not sure how to get the error message, instead you can check if user exists with same email id and then proceed with account creation. I have updated my answer, kindly check it. Accept the answer if it solves your problem. – Suresh R Aug 29 '16 at 9:04
  • Actually I was thinking of submitting it as a form so that I can get error messages in "$errors = $form_state->getErrors();". – Unnikrishnan Aug 29 '16 at 9:09
