Part of the Hydra PHP framework. Documentation: hydra.williamhleucka.com/docs.

Read-only mirror. hydrakit/validation is developed in hydra-foundation/hydra under packages/validation, and republished here on every push. A commit pushed to this repository is overwritten by the next one; issues are disabled for that reason, and a pull request opened here cannot be merged. Both belong upstream.

Validates a set of input values against a per-field list of rules. Stateless. The rules travel with each call, so one Validator can be shared and autowired. Ships no ServiceProvider; the validator has no dependencies to bind.

Rule keys are dot paths, and * walks a list: items.*.qty runs its rules once per entry and keys each error to items.0.qty. A rule is an object implementing RuleInterface, handed the value and a Context holding the rest of the input, which is how Confirmed, Same and the conditional Required* rules see the field they compare against. Exists and Unique live in hydrakit/database, which is where the connection is.
