Default field value.

The default value is used when an entity is created, either:

  • through an entity creation form; the form elements for the field are prepopulated with the default value.
  • through direct API calls (i.e. $entity->save()); the default value is added if the $entity object provides no explicit entry (actual values or "the field is empty") for the field.

The default value is expressed as a numerically indexed array of items, each item being an array of key/value pairs matching the set of 'columns' defined by the "field schema" for the field type, as exposed in the class implementing \Drupal\Core\Field\FieldItemInterface::schema() method. If the number of items exceeds the cardinality of the field, extraneous items will be ignored.

This property is overlooked if the $default_value_callback is non-empty.

Example for a integer field:

array(
    array(
        'value' => 1,
    ),
    array(
        'value' => 2,
    ),
);
