Yii2: The conditional validator always returns the required

Question

I am trying to use the Yii2 conditional validator as indicated in the manual, for example:

Model code

public function rules() { // $discharged = function($model) { return $this->discharged == 1; }; return [ [[ 'admission_date','discharge_date', 'doctor_appointment_date', 'operation_date'], 'safe'], [[ 'package','tpa_name', 'discharged', 'bed_type', 'room_category', 'ref_doctor', 'consultant_doctor', 'operation_name'], 'integer'], [['advance_amount', 'operation_charges'], 'number'], [['patient_name', 'ref_doctor_other'], 'string', 'max' => 50], [['general_regn_no', 'ipd_patient_id'], 'string', 'max' => 20], [['admission_date', 'discharge_date', 'doctor_appointment_date', 'operation_date'],'default','value'=>null], ['ipd_patient_id', 'unique'], [['bed_type','admission_date','room_category'],'required'], ['discharge_date', 'required', 'when' => function($model) { return $model->discharged == 1; }], ]; } 

and in my controller:

 public function actionCreate() { $model = new PatientDetail(); if ($model->load(Yii::$app->request->post()) && $model->save()) { return $this->redirect(['view', 'id' => $model->id]); } else { return $this->render('create', [ 'model' => $model, ]); } } 

But regardless of whether I selected or did not upload the field, which is the check box, alwasys release dates are returned as needed.

What am I doing wrong here?

Answer 1

It appears that, by default, Yii2 will perform validation on the BOTH server side and client side. Check out the example in the Conditional Validation part of the Yii2 doc :

 ['state', 'required', 'when' => function ($model) { return $model->country == 'USA'; }, 'whenClient' => "function (attribute, value) { return $('#country').val() == 'USA'; }"], 

you will also need the code 'whenClient' or, as @Alexandr Bordun said, to disable client checking for 'enableClientValidation' => false .

Answer 2

Try adding the enableClientValidation parameter as follows:

  ['discharge_date', 'required', 'when' => function($model) { return $model->discharged == 1; }, 'enableClientValidation' => false] 

Answer 3

This only works for me when using the model name (client validation).

 ['state', 'required', 'when' => function ($model) { return $model->country == 'USA'; }, 'whenClient' => "function (attribute, value) { return $('#MODELNAMEHERE-country').val() == 'USA'; }"] 

Answer 4

i had a similar requirement, I solved it using the following code

 ['discharge_date', 'required', 'whenClient' => function($model) { return $model->discharged == 1; }, 'enableClientValidation' => false] 

Answer 5

 ['package_id_fk', 'required', 'when' => function($model) {return $model->type == 'PACKAGE';}, 'enableClientValidation' => false], 

This works for me.
