PHP setter magic method.

This method is overridden so that AR attributes can be accessed like properties.

View source


  • $name (string) – Property name
  • $value (mixed) – Property value


This method is called at the beginning of inserting or updating a record.

The default implementation will trigger an EVENT_BEFORE_INSERT event when $insert is true, or an EVENT_BEFORE_UPDATE event if $insert is false. When overriding this method, make sure you call the parent implementation like the following:

public function beforeSave($insert)
    if (!parent::beforeSave($insert)) {
        return false;

    // ...custom code here...
    return true;

View source


  • $insert (boolean) – Whether this method called while inserting a record. If false, it means the method is called while updating a record.


boolean – Whether the insertion or updating should continue. If false, the insertion or updating will be cancelled.



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 \craft\db\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).

array – The behavior configurations.



Sets the named attribute value.

  • $name (string) – The attribute name
  • $value (mixed) – The attribute value.


Protected Methods

createRelationQuery()Creates a query instance for has-one or has-many relation.
deleteInternal()Deletes an ActiveRecord without considering transaction.
extractFieldsFor()Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "" The previous example would extract "id".
extractRootFields()Extracts the root field names from nested fields.
insertInternal()Inserts an ActiveRecord into DB without considering transaction.
prepareForDb()Sets the dateCreated, dateUpdated, and uid attributes on the record.
refreshInternal()Repopulates this active record with the latest data from a newly fetched instance.
resolveFields()Determines which fields can be returned by toArray().



Sets the dateCreated, dateUpdated, and uid attributes on the record.

OP_ALLAll three operations: insert, update, delete.
OP_DELETEThe delete operation. This is mainly used when overriding transactions() to specify which operations are transactional.
OP_INSERTThe insert operation. This is mainly used when overriding transactions() to specify which operations are transactional.
OP_UPDATEThe update operation. This is mainly used when overriding transactions() to specify which operations are transactional.
SCENARIO_DEFAULTThe name of the default scenario.




The event that is triggered when defining the class behaviors
