Trait ValidatorAwareTrait

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

RuntimeException

getValidator()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

boolean

setValidator()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

boolean

validator()source public deprecated

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->setValidator('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.

Deprecated

3.5.0 Use getValidator/setValidator instead.

Parameters

string|null $name optional null

the name of the validation set to return

Cake\Validation\Validator $validator optional null

Returns

Cake\Validation\Validator
