3. 11.x core/lib/Drupal/Core/Field/BaseFieldDefinition.php \Drupal\Core\Field\BaseFieldDefinition::addPropertyConstraints()

Adds constraints for a given field item property.

Adds a constraint to a property of a base field item. e.g.

// 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.
