I have a custom form that needs to display a default value from a custom user field. The field was created under /admin/config/people/accounts/fields and its machine name is field_r_period_length_sec.

//get user
$userCurrent = \Drupal::currentUser();
$uid = $userCurrent->id();
$r_period = $userCurrent->field_r_period_length_sec;

However, the value doesn't show and I get this error:

Notice: Undefined property: Drupal\Core\Session\AccountProxy::$field_r_period_length_sec

What am I doing wrong?

Berdir's answer gave me a search term that got me this:

$user = \Drupal\user\Entity\User::load(\Drupal::currentUser()->id());

After a bit of trial and error, this is the code that works, in case anyone else needs:

$user = \Drupal\user\Entity\User::load(\Drupal::currentUser()->id());
$r_period = $user->field_r_period_length_sec->value;

For multiple values, use

$r_period = $user->get('field_r_period_length_sec')->getValue();

    For anyone wanting remove the warning from PHPStorm in $r_period = $user->field_r_period_length_sec->value; add this comment /** @var $user \Drupal\user\Entity\User */ above $user = \Drupal\user\Entity\User::load(\Drupal::currentUser()->id());

The current user object is not a user entity. You need to load the user with that ID to access any field except the information specified by AccountInterface.


I don't know since when these answers doesn't work anymore, but with Drupal 8.5 the above solution return null all the time.

After investigation the solution to access custom field from a user profile is:

$activeProfile = \Drupal::getContainer()
  ->loadByUser(User::load([uid]), '[profile_machine_name]');

Then you can do

  • Thanks! I was able to get specific field from the user profile. But im wondering how can you set/update a profile field name? TIA Commented Aug 23, 2018 at 8:25

Entity::load() is based off of \Drupal::entityManager(); which is deprecated.

A better way to do this is by using entityTypeManager().

$user = \Drupal::entityTypeManager()->getStorage('user')->load($current_user->id());
$r_period = $user->field_r_period_length_sec->value;
