How To Get List Field Values As Labels Instead Of Keys

So you have a regular list text field in your entity and instead of keys, you want to get values. How do you do that? Well as usual in Drupal it will be painful 🤕 but possible 🙌:

Here’s a little function that’ll do it for you:

function getValueAsLabels($entity, $field_name) {
  // Get allowed values from the field definition.
  $allowed_values = $entity->getFieldDefinition($field_name)->getFieldStorageDefinition()->getSetting('allowed_values');
  
  // Go through each value and instead of a key return a label taken from $allowed_values.
  return array_map(function($item) use ($allowed_values) {
    return ['value' => isset($allowed_values[$item['value']]) ? $allowed_values[$item['value']] : $item['value'] ];
  }, $entity->get($field_name)->getValue());
}

A little bit of crunching and you can now get list field labels as easy as:

getValueAsLabels($node, 'field_list');

May the Force be with you.
