php - yii rules how to add validation for a non-database field?

Question

For example, I want to add a verification for field A, but it does not exist in the database. An error will be reported at this time. Are there any parameters that can be set?

Answer 1

Override rulesMethod

class Model extends \yii\db\ActiveRecord
{
    //...
    public function rules() {
        $rules = parent::rules();
        $rules[] = [['phone'],'integer','message'=>'手机号码必须是数字'];
        return $rules;
    }
    //...
}
