How to execute validation method with ajax?

Question

Yii

Hello,

public function rules() {
     return [
         ['field' ,'method'],
     ];
}

public function method($attribute,$params) {

How to make this method executed by Ajax???

Answer 1

You need to create your own MethodValidator:

public function rules() {
     return [
         ['field' , MethodValidator::className()],
     ];
}

And already in the MethodValidator, using the clientValidateAttribute() method, build the validation logic on the client side.
