Trait ValidatorAwareTrait
A trait that provides methods for building and interacting with Validators.
This trait is useful when building ORM like features where the implementing class wants to build and customize a variety of validator instances.
This trait expects that classes including it define two constants:
-
DEFAULT_VALIDATOR
- The default validator name. -
VALIDATOR_PROVIDER_NAME
- The provider name the including class is assigned in validators.
If the including class also implements events the Model.buildValidator
event will be triggered when validators are created.

Method Summary
- createValidator() protectedCreates a validator using a custom method inside your class.
- getValidator() public
Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.
- hasValidator() publicChecks whether or not a validator has been set.
- setValidator() publicThis method stores a custom validator under the given name.
- validationDefault() public
Returns the default validator object. Subclasses can override this function to add a default validation set to the validator object.
- validationMethodExists() protectedChecks if validation method exists.
- validator() public
Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.
Method Detail
createValidator()source protected
createValidator( string $name )
Creates a validator using a custom method inside your class.
This method is used only to build a new validator and it does not store it in your object. If you want to build and reuse validators, use getValidator() method instead.
Parameters
- string
$name
- The name of the validation set to create.
Returns
Cake\Validation\Validator
Throws
RuntimeExceptiongetValidator()source public
getValidator( string|null $name null )
Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.
If a validator has not been set earlier, this method will build a valiator using a method inside your class.
For example, if you wish to create a validation set called 'forSubscription', you will need to create a method in your Table subclass as follows:
public function validationForSubscription($validator) { return $validator ->add('email', 'valid-email', ['rule' => 'email']) ->add('password', 'valid', ['rule' => 'notBlank']) ->requirePresence('username'); } $validator = $this->getValidator('forSubscription');
You can implement the method in validationDefault
in your Table subclass should you wish to have a validation set that applies in cases where no other set is specified.
If a $name argument has not been provided, the default validator will be returned. You can configure your default validator name in a DEFAULT_VALIDATOR
class constant.
Parameters
- string|null
$name
optional null - The name of the validation set to return.
Returns
Cake\Validation\Validator
hasValidator()source public
hasValidator( string $name )
Checks whether or not a validator has been set.
Parameters
- string
$name
- The name of a validator.
Returns
booleansetValidator()source public
setValidator( string $name , Cake\Validation\Validator $validator )
This method stores a custom validator under the given name.
You can build the object by yourself and store it in your object:
$validator = new \Cake\Validation\Validator($table); $validator ->add('email', 'valid-email', ['rule' => 'email']) ->add('password', 'valid', ['rule' => 'notBlank']) ->allowEmpty('bio'); $this->setValidator('forSubscription', $validator);
Parameters
- string
$name
- The name of a validator to be set.
-
Cake\Validation\Validator
$validator
- Validator object to be set.
Returns
$this
validationDefault()source public
validationDefault( Cake\Validation\Validator $validator )
Returns the default validator object. Subclasses can override this function to add a default validation set to the validator object.
Parameters
-
Cake\Validation\Validator
$validator
The validator that can be modified to add some rules to it.
Returns
Cake\Validation\Validator
validationMethodExists()source protected
validationMethodExists( string $name )
Checks if validation method exists.
Parameters
- string
$name
- Validation method name.
Returns
booleanvalidator()source public
validator( string|null $name null , Cake\Validation\Validator $validator null )
Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.
There are two different ways of creating and naming validation sets: by creating a new method inside your own Table subclass, or by building the validator object yourself and storing it using this method.
For example, if you wish to create a validation set called 'forSubscription', you will need to create a method in your Table subclass as follows:
public function validationForSubscription($validator) { return $validator ->add('email', 'valid-email', ['rule' => 'email']) ->add('password', 'valid', ['rule' => 'notBlank']) ->requirePresence('username'); }
Otherwise, you can build the object by yourself and store it in the Table object:
$validator = new \Cake\Validation\Validator($table); $validator ->add('email', 'valid-email', ['rule' => 'email']) ->add('password', 'valid', ['rule' => 'notBlank']) ->allowEmpty('bio'); $table->validator('forSubscription', $validator);
You can implement the method in validationDefault
in your Table subclass should you wish to have a validation set that applies in cases where no other set is specified.
