Pass values ​​from search form (checkboxList) to search model in Yii2?

Question

Yii

Hello! Can you please tell me how to pass values ​​from the search form (checkboxList) to the search model in Yii2?
view:

<?= $form->field($searchModel, 'type')->checkboxList(['0' => 'Доход', '1' => 'Расход']) ?>

controller:

$searchModel = new ModelSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->post());

searchModel:

public function search($params)
    {
        $query = Payment::find()->orderBy('pay_date ASC');

        // add conditions that should always apply here

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
            'pagination' => false,
        ]);
  
        $this->load($params);
        if (!$this->validate()) {
            return $dataProvider;
        }

        if (is_array($this->type)) {
        
            $query->andFilterWhere(['in', 'type', array_keys($this->type)]);
        } 
        else {
            $query->andFilterWhere([
                'type' => $this->type
            ]);
        }

        // grid filtering conditions
        $query->andFilterWhere([
            'id' => $this->id,
            'category_id' => $this->category_id,
            'pay_date' => $this->pay_date,
            'status' => $this->status,
        ]);

        $query->andFilterWhere(['like', 'name', $this->name])
            ->andFilterWhere(['user_id' => Yii::$app->user->identity->id]);

        return $dataProvider;
    }

But for some reason the array is not assigned. What could be the snag?
Thanks for the replies!

Got it! The problem was in the validation rules
