validateMultiple() public static method
Validates an array of model instances and returns an error message array indexed by the attribute IDs. This is a helper method that simplifies the way of writing AJAX validation code for tabular input. For example, you may use the following code in a controller action to respond to an AJAX validation request: // ... load $models ...
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = Response::FORMAT_JSON;
return Active
