Suppose we have something like this in the controller:
if ($model->load(Yii::$app->request->post())) {
$model->save();
}
And in the model we have:
['some_ids', 'each', 'rule' => ['integer']],
['some_ids', 'filter', 'filter' => 'array_unique'],
['some_ids', 'filter', 'filter' => [$this, 'checkSomeIds']]
// whatever else
So, what’s the workaround to handle an empty selection using the Yii coding style?
Thanks.
