isValid
属性
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.
