Class ModelValidator
ModelValidator object encapsulates all methods related to data validations for a model It also provides an API to dynamically change validation rules for each model field.
Implements ArrayAccess to easily modify rules as usually done with Model::$validate
definition array
- ModelValidator implements ArrayAccess, IteratorAggregate, Countable

Method Detail
__constructsource public
__construct( Model $Model )
Constructor
Parameters
-
Model
$Model
- A reference to the Model the Validator is attached to
_parseRulessource protected
_parseRules( )
Sets the CakeValidationSet objects from the Model::$validate
property If Model::$validate
is not set or empty, this method returns false. True otherwise.
Returns
boolean
true if
Model::$validate
was processed, false otherwise_triggerBeforeValidatesource protected
_triggerBeforeValidate( array $options array() )
Propagates beforeValidate event
Parameters
- array
$options
optional array() - Options to pass to callback.
Returns
boolean
bool
Triggers
Model.beforeValidate $model, array($options)_validateWithModelssource protected
_validateWithModels( array $options )
Runs validation for hasAndBelongsToMany associations that have 'with' keys set and data in the data set.
Parameters
- array
$options
- Array of options to use on Validation of with models
Returns
boolean
Failure of validation on with models.
See
Model::validates()
_validationListsource protected
_validationList( array $fieldList array() )
Processes the passed fieldList and returns the list of fields to be validated
Parameters
- array
$fieldList
optional array() - list of fields to be used for validation
Returns
CakeValidationSet[]
List of validation rules to be applied
addsource public
add( string $field , string|array|CakeValidationSet $name , array|CakeValidationRule $rule null )
Adds a new rule to a field's rule set. If second argument is an array or instance of CakeValidationSet then rules list for the field will be replaced with second argument and third argument will be ignored.
Example:
$validator ->add('title', 'required', array('rule' => 'notBlank', 'required' => true)) ->add('user_id', 'valid', array('rule' => 'numeric', 'message' => 'Invalid User')) $validator->add('password', array( 'size' => array('rule' => array('lengthBetween', 8, 20)), 'hasSpecialCharacter' => array('rule' => 'validateSpecialchar', 'message' => 'not valid') ));
Parameters
- string
$field
- The name of the field where the rule is to be added
- string|array|
CakeValidationSet
$name
- name of the rule to be added or list of rules for the field
- array|
CakeValidationRule
$rule
optional null - or list of rules to be added to the field's rule set
Returns
self
self
countsource public
count( )
Returns the number of fields having validation rules
Returns
integer
int
Implementation of
Countable::count()
errorssource public
errors( string $options array() )
Returns an array of fields that have failed validation. On the current model. This method will actually run validation rules over data, not just return the messages.
Parameters
- string
$options
optional array() - An optional array of custom options to be made available in the beforeValidate callback
Returns
array
Array of invalid fields
See
ModelValidator::validates()
Triggers
Model.afterValidate $modelgetFieldsource public
getField( string $name null )
Returns a CakeValidationSet object containing all validation rules for a field, if no params are passed then it returns an array with all CakeValidationSet objects for each field
Parameters
- string

optional null - [optional] The fieldname to fetch. Defaults to null.
Returns
CakeValidationSet|array|null
CakeValidationSet|array|null
getIteratorsource public
getIterator( )
Returns an iterator for each of the fields to be validated
Returns
ArrayIterator
ArrayIterator
Implementation of
IteratorAggregate::getIterator()
getMethodssource public
getMethods( )
Gets all possible custom methods from the Model and attached Behaviors to be used as validators
Returns
array
List of callables to be used as validation methods
invalidatesource public
invalidate( string $field , string $message true )
Marks a field as invalid, optionally setting a message explaining why the rule failed
Parameters

Sets the rule set for a field
Parameters
- string
$field
- name of the field to set
- array|
CakeValidationSet
$rules
- set of rules to apply to field
Implementation of
ArrayAccess::offsetSet()
offsetUnsetsource public
offsetUnset( string $field )
Unsets the rule set for a field
Parameters
- string
$field
- name of the field to unset
Implementation of
ArrayAccess::offsetUnset()
removesource public
remove( string $field , string $rule null )
Removes a rule from the set by its name

$validator ->remove('title', 'required') ->remove('user_id')
Parameters
- string
$field
- The name of the field from which the rule will be removed
- string
$rule
optional null - the name of the rule to be removed
Returns
self
self
setValidationDomainsource public
setValidationDomain( string $validationDomain null )
Sets the I18n domain for validation messages. This method is chainable.
Parameters
- string
$validationDomain
optional null - [optional] The validation domain to be used.
Returns
self
self
validateAssociatedsource public
validateAssociated( array $data , array $options array() )
Validates a single record, as well as all its directly associated records.
Options
- atomic: If true (default), returns boolean. If false returns array.
- fieldList: Equivalent to the $fieldList parameter in Model::save()
- deep: If set to true, not only directly associated data , but deeper nested associated data is validated as well.
Warning: This method could potentially change the passed argument $data
, If you do not want this to happen, make a copy of $data
before passing it to this method
Parameters
- array
$data
- $data Record data to validate. This should be an array indexed by association name.
- array
$options
optional array() - Options to use when validating record data (see above), See also $options of validates().
Returns
array|boolean
If atomic: True on success, or false on failure. Otherwise: array similar to the $data array passed, but values are set to true/false depending on whether each record validated successfully.
validateManysource public
validateMany( array $data , array $options array() )
Validates multiple individual records for a single model
Options
- atomic: If true (default), returns boolean. If false returns array.
- fieldList: Equivalent to the $fieldList parameter in Model::save()
- deep: If set to true, all associated data will be validated as well.
Warning: This method could potentially change the passed argument $data
, If you do not want this to happen, make a copy of $data
before passing it to this method
Parameters
- array
$data
- $data Record data to validate. This should be a numerically-indexed array
- array
$options
optional array() - Options to use when validating record data (see above), See also $options of validates().
Returns
mixed
If atomic: True on success, or false on failure. Otherwise: array similar to the $data array passed, but values are set to true/false depending on whether each record validated successfully.
validatessource public
validates( array $options array() )
Returns true if all fields pass validation. Will validate hasAndBelongsToMany associations that use the 'with' key as well. Since Model::_saveMulti
is incapable of exiting a save operation.
Will validate the currently set data. Use Model::set()
or Model::create()
to set the active data.
Parameters
- array
$options
optional array() - An optional array of custom options to be made available in the beforeValidate callback
Returns
boolean
True if there are no errors
