检查列表中的一个属性是否已设置

Question

I have a model like so

class Person extends yii\db\ActiveRecord
{
  public $desk_no;
  public $mobl_no;
  public $faxx_no;
}

I want to add a validation rule which would read something like this in English

One of the *_no attributes is required; I don't care which one.

How do I go about that in yii2?

Answer 1

you could use such validation for example

['desk_no', 'required', 'when' => function($model) {
    return is_null($model->mobl_no)&&is_null($model->faxx_no);
}, message => "One of the *_no attributes is required; I don't care which one." ],

but if this logic can change, i prefer custom validator
