Strict Mode

By default, the validator operates in “strict” mode. This means that the library expects you to define explicit validation rules for all properties within an object or keys within an array that you pass for validation. If a property/key lacks a corresponding rule, the library will throw an exception.

Purpose#

Strict mode helps enforce data integrity and can prevent unexpected behavior. By requiring explicit validation, it encourages developers to think carefully about the expected format and constraints of the data they are handling.

Example (Strict Mode):

$data = ['email' => '[email protected]'];
$rules = [];

$validator->validate($data, $rules); // will throw a `LogicException` with message "email: Validation rule is not configured."

Disabling Strict Mode#

If needed, you can disable strict mode by passing the strict: false flag to the validate() method. This allows you to validate only the data for which you’ve explicitly provided rules, while ignoring other properties or array elements.

Example (Non-Strict Mode):

use Norvica\Validation\Options;

$data = ['email' => '[email protected]'];
$rules = [];

$validator->validate($data, $rules, new Options(strict: false)); // will pass
