Validation (to be written)¶

• Validation API: TYPO3FLOW3Validation
• explain ValidatorResolver::createValidator()
• build validator for model object: ValidatorResolver
• by default, validation happens inside the Controller before the action is called and before persisting an object

Partial Validation¶

• if you only want to validate parts of your objects, f.e. want to store incomplete objects in the database, you can assign special Validation Groups.
• It is possible to specify a list of validation groups at each @FLOW3Validate annotation, if none is specified the validation group “Default” is assigned to the validator
• When invoking validation, f.e. in the MVC layer or in persistence, you can also specify a list of to-be-executed validation groups. A validator is only executed if at least one validation group overlap.

Example:

/**
 * @FLOW3\Validate(name='Required')
 */
protected $prop1;

/**
 * @FLOW3\Validate(name='Required', validationGroups={'Default')})
 */
protected $prop2;

/**
 * @FLOW3\Validate(name='Required', validationGroups={'Persistence')})
 */
protected $prop3;

/**
 * @FLOW3\Validate(name='Required', validationGroups={'Controller')})
 */
protected $prop3;

• In Persistence, validation is invoked with validation groups Default and Persistence
• In Controller, validation is invoked with validation groups Default and Controller

Combined with the above example this means:

• validation for prop1 and prop2 are the same, as the “Default” validation group is added if none is specified
• validation for prop1 and prop2 are executed both on persisting and inside the controller
• validation for $prop3 is only executed in persistence, but not in controller
• validation for $prop4 is only executed in controller, but not in persistence
