Validation Constraints Reference

Warning: You are browsing the documentation for Symfony 4.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

The Validator is designed to validate objects against constraints. In real life, a constraint could be: "The cake must not be burned". In Symfony, constraints are similar: They are assertions that a condition is true.
