public BaseFieldDefinition::addPropertyConstraints($name, array $constraints)
Adds constraints for a given field item property.
Adds a constraint to a property of a base field item. e.g.
1 2 3 4 5 6 7 8 | // Limit the field item's value property to the range 0 through 10.// e.g. $node->size->value.$field->addPropertyConstraints('value', [ 'Range' => [ 'min' => 0, 'max' => 10, ]]); |
If you want to add a validation constraint that applies to the \Drupal\Core\Field\FieldItemList, use BaseFieldDefinition::addConstraint() instead.
Note: passing a new set of options for an existing property constraint will overwrite with the new options.
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.
