Validation

Validation in Semitexa PHP: payload validation at the request boundary, the core validators and UI field validation built on the same rules.

• Core Validators

  Trait-based validators for presence, type, format, numbers, dates, choices, collections and domain rules, run automatically before handlers.

• UI Field Validation

  The server-side rules DSL for platform-ui fields, including cross-field rules such as sameAsField.

• Payload Validation

  Where validation sits in the pipeline, how payload rules and helpers are written, hydration, the failure response, and session and cookie payloads.
