        return [
            [['position', 'location', 'status'], 'required'],
            [['description'], 'string'],
            [[ 'phone_number', 'company'], 'integer'],

controller action

 public function actionCreate()
 {
     $model = new Advertisement();

     if ($model->load(Yii::$app->request->post()) ) {
         $model->company = Yii::$app->user->identity->id;
         $model->created_at = date("Y-m-d H:i:s");
         $model->date_added = date("Y-m-d H:i:s");

          $model->save();
          return $this->redirect(['view', 'id' => $model->id]);
     } else {
            return $this->render('create', [
                'model' => $model,
            ]);
     }
 }

any help ?

Answer 1

You need to disable skipOnEmpty property of Validator for it .. For More Info Read

 Update your code as 

  [['phone_number','email'], 'myRule' ,'skipOnEmpty' => false],

Answer 2

I think you hsold use $attribute and not $attribute_name

public function myRule($attribute_name, $params)
{

    if (empty($this->email)
        && empty($this->phone_number)
    ) {
        $this->addError($attribute, Yii::t('app', 'either Phone or Email required'));

        return false;
    }

    return true;
}

from yii2 doc

addError() public method Adds an error about the specified attribute to the model object.

This is a helper method that performs message selection and internationalization. public void addError ( $model, $attribute, $message, $params = [] )

Try this action create

public function actionCreate()
{
    $model = new Advertisement();

    if ($model->load(Yii::$app->request->post()) ) {
        if ($model->validate()) {


          $model->company = Yii::$app->user->identity->id;
          $model->created_at = date("Y-m-d H:i:s");
          $model->date_added = date("Y-m-d H:i:s");

          $model->save();
          return $this->redirect(['view', 'id' => $model->id]);
        }
        else {
        $errors = $model->errors;
        return $this->render('create', [
            'model' => $model,
        ]);
      }
    }  else {
       return $this->render('create', [
            'model' => $model,
        ]);
    }
}
