FieldConfigBase::setPropertyConstraints

public FieldConfigBase::setPropertyConstraints($name, array $constraints)

Sets constraints for a given field item property.

Note: this overwrites any existing property constraints. If you need to add to the existing constraints, use \Drupal\Core\Field\FieldConfigInterface::addPropertyConstraints()

Note that constraints added via this method are not stored in configuration and as such need to be added at runtime using hook_entity_bundle_field_info_alter().

Parameters

string $name: The name of the property to set constraints for.

array $constraints: The constraints to set.

Return value

static The object itself for chaining.

Overrides FieldConfigInterface::setPropertyConstraints
