}
Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.

Defined in: yii\base\Component::__get()
Returns the value of a component property.
This method will check in the following order and act accordingly:
- a property defined by a getter: return the getter result
- a property of a behavior: return the behavior property value
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $component->property;
.

public void addErrors ( array $items ) | ||
$items | array |
A list of errors. The array keys must be attribute names. The array values should be error messages. If an attribute has multiple errors, these errors must be given in terms of an array. You may use the result of getErrors() as the value for this parameter. |
public function addErrors(array $items)

}
}
Defined in: yii\base\Model::afterValidate()
This method is invoked after validation ends.
The default implementation raises an afterValidate
event.
You may override this method to do postprocessing after validation.
Make sure the parent implementation is invoked so that the event can be raised.
public void afterValidate ( ) |
public function afterValidate()
{
$this->trigger(self::EVENT_AFTER_VALIDATE);
}
Defined in: yii\base\Component::attachBehavior()
Attaches a behavior to this component.
This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.
See also detachBehavior().
public yii\base\Behavior attachBehavior ( $name, $behavior ) | ||
$name | string |
The name of the behavior. |
$behavior | string|array|yii\base\Behavior |
The behavior configuration. This can be one of the following:
|
return | yii\base\Behavior |
The behavior object |
---|
public function attachBehavior($name, $behavior)
{
$this->ensureBehaviors();
return $this->attachBehaviorInternal($name, $behavior);
}
Defined in: yii\base\Component::attachBehaviors()
Attaches a list of behaviors to the component.
Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.
See also attachBehavior().
public void attachBehaviors ( $behaviors ) | ||
$behaviors | array |
List of behaviors to be attached to the component |
public function attachBehaviors($behaviors)
{
$this->ensureBehaviors();
foreach ($behaviors as $name => $behavior) {
$this->attachBehaviorInternal($name, $behavior);
}
}
Defined in: yii\base\Model::attributeHints()
Returns the attribute hints.
Attribute hints are mainly used for display purpose. For example, given an attribute
isPublic
, we can declare a hint Whether the post should be visible for not logged in users
,
which provides user-friendly description of the attribute meaning and can be displayed to end users.
Unlike label hint will not be generated, if its explicit declaration is omitted.
Note, in order to inherit hints defined in the parent class, a child class needs to
merge the parent hints with child hints using functions such as array_merge()
.
public array attributeHints ( ) | ||
return | array |
Attribute hints (name => hint) |
---|
public function attributeHints()
{
return [];
}
Returns the attribute labels.
Attribute labels are mainly used for display purpose. For example, given an attribute
firstName
, we can declare a label First Name
which is more user-friendly and can
be displayed to end users.
By default an attribute label is generated using generateAttributeLabel(). This method allows you to explicitly specify attribute labels.
Note, in order to inherit labels defined in the parent class, a child class needs to
merge the parent labels with child labels using functions such as array_merge()
.
public array attributeLabels ( ) | ||
return | array |
Attribute labels (name => label) |
---|
public function attributeLabels()
{
return [
'duration' => 'Duration ≥'
];
}
Defined in: yii\base\Model::attributes()
Returns the list of attribute names.
By default, this method returns all public non-static properties of the class. You may override this method to change the default behavior.
public string[] attributes ( ) | ||
return | string[] |
List of attribute names. |
---|
public function attributes()
{
$class = new ReflectionClass($this);
$names = [];
foreach ($class->getProperties(\ReflectionProperty::IS_PUBLIC) as $property) {
if (!$property->isStatic()) {
$names[] = $property->getName();
}
}
return $names;
}
Defined in: yii\base\Model::beforeValidate()
This method is invoked before validation starts.
The default implementation raises a beforeValidate
event.
You may override this method to do preliminary checks before validation.
Make sure the parent implementation is invoked so that the event can be raised.
public boolean beforeValidate ( ) | ||
return | boolean |
Whether the validation should be executed. Defaults to true. If false is returned, the validation will stop and the model is considered invalid. |
---|
public function beforeValidate()
{
$event = new ModelEvent();
$this->trigger(self::EVENT_BEFORE_VALIDATE, $event);
return $event->isValid;
}
Defined in: yii\base\Component::behaviors()
Returns a list of behaviors that this component should behave as.
Child classes may override this method to specify the behaviors they want to behave as.
The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:
'behaviorName' => [
'class' => 'BehaviorClass',
'property1' => 'value1',
'property2' => 'value2',
]
Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.
Behaviors declared in this method will be attached to the component automatically (on demand).
public array behaviors ( ) | ||
return | array |
The behavior configurations. |
---|
public function behaviors()
{
return [];
}
Defined in: yii\base\Component::canGetProperty()
Returns a value indicating whether a property can be read.
A property can be read if:
- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true); - an attached behavior has a readable property of the given name (when
$checkBehaviors
is true).
See also canSetProperty().

Defined in: yii\base\Component::canSetProperty()
Returns a value indicating whether a property can be set.
A property can be written if:
- the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true); - an attached behavior has a writable property of the given name (when

This method is similar to fields() except that the list of fields returned by this method are not returned by default by toArray(). Only when field names to be expanded are explicitly specified when calling toArray(), will their values be exported.
The default implementation returns an empty array.
You may override this method to return a list of expandable fields based on some context information (e.g. the current application user).
See also:
public array extraFields ( ) | ||
return | array |
The list of expandable field names or field definitions. Please refer to fields() on the format of the return value. |
---|
public function extraFields()
{
return [];
}
Defined in: yii\base\ArrayableTrait::extractFieldsFor()
Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "id".
protected array extractFieldsFor ( array $fields, $rootField ) | ||
$fields | array |
The fields requested for extraction |
$rootField | string |
The root field for which we want to extract the nested fields |
return | array |
Nested fields extracted for the given field |
---|
protected function extractFieldsFor(array $fields, $rootField)
{
$result = [];
foreach ($fields as $field) {
if (0 === strpos($field, "{$rootField}.")) {
$result[] = preg_replace('/^' . preg_quote($rootField, '/') . '\./i', '', $field);
}
}
return array_unique($result);
}
Defined in: yii\base\ArrayableTrait::extractRootFields()
Extracts the root field names from nested fields.
Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "item".
protected array extractRootFields ( array $fields ) | ||
$fields | array |
The fields requested for extraction |
return | array |
Root fields extracted from the given nested fields |
---|
protected function extractRootFields(array $fields)
{
$result = [];
foreach ($fields as $field) {
$result[] = current(explode('.', $field, 2));
}
if (in_array('*', $result, true)) {
$result = [];
}
return array_unique($result);
}
Defined in: yii\base\ArrayableTrait::fields()
Returns the list of fields that should be returned by default by toArray() when no specific fields are specified.
A field is a named element in the returned array by toArray().
This method should return an array of field names or field definitions. If the former, the field name will be treated as an object property name whose value will be used as the field value. If the latter, the array key should be the field name while the array value should be the corresponding field definition which can be either an object property name or a PHP callable returning the corresponding field value. The signature of the callable should be:
function ($model, $field) {
// return field value
}
For example, the following code declares four fields:
email
: the field name is the same as the property nameemail
;firstName
andlastName
: the field names arefirstName
andlastName
, and their values are obtained from thefirst_name
andlast_name
properties;fullName
: the field name isfullName
. Its value is obtained by concatenatingfirst_name
andlast_name
.
return [
'email',
'firstName' => 'first_name',
'lastName' => 'last_name',
'fullName' => function () {
return $this->first_name . ' ' . $this->last_name;
},
];
In this method, you may also want to return different lists of fields based on some context information. For example, depending on the privilege of the current application user, you may return different sets of visible fields or filter out some fields.
The default implementation of this method returns the public object member variables indexed by themselves.
See also toArray().
public array fields ( ) | ||
return | array |
The list of field names or field definitions. |
---|
public function fields()
{
$fields = array_keys(Yii::getObjectVars($this));
return array_combine($fields, $fields);
}
Defined in: yii\base\Model::formName()
Returns the form name that this model class should use.
The form name is mainly used by yii\widgets\ActiveForm to determine how to name the input fields for the attributes in a model. If the form name is "A" and an attribute name is "b", then the corresponding input name would be "A[b]". If the form name is an empty string, then the input name would be "b".
The purpose of the above naming schema is that for forms which contain multiple different models, the attributes of each model are grouped in sub-arrays of the POST-data and it is easier to differentiate between them.
By default, this method returns the model class name (without the namespace part) as the form name. You may override it when the model is used in different forms.
See also load().
public string formName ( ) | ||
return | string |
The form name of this model class. |
---|---|---|

}
return $reflector->getShortName();
}
Defined in: yii\base\Model::generateAttributeLabel()
Generates a user friendly attribute label based on the give attribute name.
This is done by replacing underscores, dashes and dots with blanks and changing the first letter of each word to upper case. For example, 'department_name' or 'DepartmentName' will generate 'Department Name'.

Defined in: yii\base\Model::getValidators()
Returns all the validators declared in rules().
This method differs from getActiveValidators() in that the latter only returns the validators applicable to the current $scenario.

Defined in: yii\base\Model::isAttributeRequired()
Returns a value indicating whether the attribute is required.
This is determined by checking if the attribute is associated with a required validation rule in the current $scenario.
Note that when the validator has a conditional validation applied using

regardless of the when
condition because it may be called be
before the model is loaded with data.

Defined in: yii\base\Model::load()
Populates the model with input data.
This method provides a convenient shortcut for:
if (isset($_POST['FormName'])) {
$model->attributes = $_POST['FormName'];
if ($model->save()) {
// handle success
}
}
which, with load()
can be written as:
if ($model->load($_POST) && $model->save()) {
// handle success
}
load()
gets the 'FormName'
from the model's formName() method (which you may override), unless the
$formName
parameter is given. If the form name is empty, load()
populates the model with the whole of $data
,
instead of $data['FormName']
.
Note, that the data being populated is subject to the safety check by setAttributes().
public boolean load ( $data, $formName = null ) | ||
$data | array |

}
Defined in: yii\base\Model::loadMultiple()
Populates a set of models with the data from end user.
This method is mainly used to collect tabular data input.
The data to be loaded for each model is $data[formName][index]
, where formName
refers to the value of formName(), and index
the index of the model in the $models
array.
If formName() is empty, $data[index]
will be used to populate each model.
The data being populated to each model is subject to the safety check by setAttributes().
public static boolean loadMultiple ( $models, $data, $formName = null ) | ||
$models | array |
The models to be populated. Note that all models should have the same class. |
$data | array |
The data array. This is usually |

{
if ($formName === null) {

The event handler must be a valid PHP callback. The following are some examples:
function ($event) { ... } // anonymous function
[$object, 'handleClick'] // $object->handleClick()
['Page', 'handleClick'] // Page::handleClick()
'handleClick' // global function handleClick()
The event handler must be defined with the following signature,

Returns the validation rules for attributes.
Validation rules are used by validate() to check if attribute values are valid. Child classes may override this method to declare different validation rules.
Each rule is an array with the following structure:
[
['attribute1', 'attribute2'],
'validator type',
'on' => ['scenario1', 'scenario2'],
//...other parameters...
]
where
- attribute list: required, specifies the attributes array to be validated, for single attribute you can pass a string;
- validator type: required, specifies the validator to be used. It can be a built-in validator name, a method name of the model class, an anonymous function, or a validator class name.
- on: optional, specifies the scenarios array in which the validation rule can be applied. If this option is not set, the rule will apply to all scenarios.
- additional name-value pairs can be specified to initialize the corresponding validator properties. Please refer to individual validator class API for possible properties.
A validator can be either an object of a class extending yii\validators\Validator, or a model class method (called inline validator) that has the following signature:
// $params refers to validation parameters given in the rule
function validatorName($attribute, $params)
In the above $attribute
refers to the attribute currently being validated while $params
contains an array of
validator configuration options such as max
in case of string
validator. The value of the attribute currently being validated
can be accessed as $this->$attribute
. Note the $
before attribute
; this is taking the value of the variable
$attribute
and using it as the name of the property to access.
Yii also provides a set of built-in validators. Each one has an alias name which can be used when specifying a validation rule.
Below are some examples:
[
// built-in "required" validator
[['username', 'password'], 'required'],
// built-in "string" validator customized with "min" and "max" properties
['username', 'string', 'min' => 3, 'max' => 12],
// built-in "compare" validator that is used in "register" scenario only
['password', 'compare', 'compareAttribute' => 'password2', 'on' => 'register'],
// an inline validator defined via the "authenticate()" method in the model class
['password', 'authenticate', 'on' => 'login'],
// a validator of class "DateRangeValidator"
['dateRange', 'DateRangeValidator'],
];
Note, in order to inherit rules defined in the parent class, a child class needs to
merge the parent rules with child rules using functions such as array_merge()
.

}
Defined in: yii\base\Model::scenarios()
Returns a list of scenarios and the corresponding active attributes.
An active attribute is one that is subject to validation in the current scenario. The returned array should be in the following format:
[
'scenario1' => ['attribute11', 'attribute12', ...],
'scenario2' => ['attribute21', 'attribute22', ...],
...
]
By default, an active attribute is considered safe and can be massively assigned.
If an attribute should NOT be massively assigned (thus considered unsafe),
please prefix the attribute with an exclamation character (e.g. '!rank'
).
The default implementation of this method will return all scenarios found in the rules() declaration. A special scenario named SCENARIO_DEFAULT will contain all attributes found in the rules(). Each scenario will be associated with the attributes that are being validated by the validation rules that apply to the scenario.

Defined in: yii\base\ArrayableTrait::toArray()
Converts the model into an array.
This method will first identify which fields to be included in the resulting array by calling resolveFields().
It will then turn the model into an array with these fields. If $recursive
is true,
any embedded objects will also be converted into arrays.
When embedded objects are yii\base\Arrayable, their respective nested fields will be extracted and passed to toArray().
If the model implements the yii\web\Linkable interface, the resulting array will also have a _link
element
which refers to a list of links as specified by the interface.
public array toArray ( array $fields = [], array $expand = [], $recursive = true ) | ||
$fields | array |
The fields being requested.
If empty or if it contains '*', all fields as specified by fields() will be returned.
Fields can be nested, separated with dots (.). e.g.: item.field.sub-field
|
$expand | array |
The additional fields being requested for exporting. Only fields declared in extraFields()
will be considered.
Expand can also be nested, separated with dots (.). e.g.: item.expand1.expand2
|
$recursive | boolean |
Whether to recursively return array representation of embedded objects. |
return | array |
The array representation of the object |

Defined in: yii\base\Model::validate()
Performs the data validation.
This method executes the validation rules applicable to the current $scenario. The following criteria are used to determine whether a rule is currently applicable:
- the rule must be associated with the attributes relevant to the current scenario;
- the rules must be effective for the current scenario.
This method will call beforeValidate() and afterValidate() before and after the actual validation, respectively. If beforeValidate() returns false, the validation will be cancelled and afterValidate() will not be called.
Errors found during the validation can be retrieved via getErrors(), getFirstErrors() and getFirstError().
public boolean validate ( $attributeNames = null, $clearErrors = true ) | ||
