protected property FieldConfigBase::$default_value in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 core/lib/Drupal/Core/Field/FieldConfigBase.php \Drupal\Core\Field\FieldConfigBase::default_value

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 hook_field_schema(). 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,
  ),
);
