Yii2 - 使用键验证属性

Question

I have a problem with attribute key validation.

In model I have property like:

public $_fileds = [];

and My view

  <?= $form->field($model, '_fileds[name]') ?>
  <?= $form->field($model, '_fileds[type]') ?>

I want to set "_fields[name]" as requierd field. For example I tried add to rules in model something like this:

public function rules()
{
  return [
    [['_fields[name]'], 'required']
 ];
}

but this not working:(

Does anyone have any solution?

Sorry for my not good English and thanks in advance for all solutions.

You can write your own validation.

Remove: public $_fileds = [];

public function rules()
{
  return [
    [['_fields[name]'], 'validateName']
 ];
}

In same model class:

public function validateName():bool
    {
        ... your checks(if fails return false) ...
        return true;
    }

But there is one issue: if some of checks fails you, in normal cases, need to set error message using $this->addError() which will correctly work with attributes which are not array elements because as first element of $this->addError() you need to pass attribute name as string where '_fileds' is ok but '_fileds[name]' won't work. So you also need to find a way to return errors if they appear. Same issue with attribute labels and hints.
