Property Details
criteria
property
(available since v1.1.5)
public CDbCrireria $criteria;
the query criteria that is passed as a parameter to a find method of CActiveRecord. Note that this property is only used by CActiveRecord::onBeforeFind event. This property could be null.
isValid
property
public boolean $isValid;
whether the model is in valid status and should continue its normal method execution cycles. Defaults to true. For example, when this event is raised in a CFormModel object that is executing CModel::beforeValidate, if this property is set false by the event handler, the CModel::validate method will quit after handling this event. If true, the normal execution cycles will continue, including performing the real validations and calling CModel::afterValidate.
