Getting an array of checkbox values in the controller

Question

In the form there is such group of checkboxes

$form->field($model, 'ingredients')->checkboxList(
        ArrayHelper::map($ingredients, 'id', 'name')
    )

In html it looks like

<input name="Dish[ingredients][]" value="1" type="checkbox">
<input name="Dish[ingredients][]" value="2" type="checkbox">

How I can get an array of checkboxes values in the actionCreate method of controller?

I trying do it like this

Yii::$app->request->post('Dish[ingredients]', [])

but I get an empty array.

Addition:

Ingredients property is not present in generated model Dish, I'm had added it later by the hand. Dish and Ingredients have a many to many relationship. How to add ingredients to theDish model correctly?

Now if I do

$model = new Dish();
$model->load(Yii::$app->request->post());
var_dump($model->ingredients);

$model->ingredients is empty array.

Create the ingredients attribute in the Dish model:

public class Dish {
  public $ingredients;
  ...
}

Load all the post data to your model and then access the ingredients array:

$model = new Dish();
$model->load(Yii::$app->request->post());
var_dump($model->ingredients);

Just create an attirbute where to load the array, and then work with it

I had added setter for ingredients and it all worked. Getter was already. With public property also works. Thank you
