Yii2 insert data from CheckBoxList - yii2

Question

In my Form:
<?= GridView::widget([
'id' => 'griditems',
'dataProvider' => $dataProvider,
'columns' => [
'receiver_name',
'receiver_phone',
'item_price',
'shipment_price',
['class' => 'yii\grid\CheckboxColumn'],
],
]); ?>
In my Controller:
public function actionCreate()
{
$model = new Package();
$searchModel = new ShipmentSearch();
$searchModel->shipment_position=1; // الشحنه في مقر الشركة
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
if ($model->loadAll(Yii::$app->request->post())){
$select = Yii::$app->request->post('selection');
foreach($select as $id){
$shipment= shipment::findOne((int)$id);
$model->company_id=1;
$model->shipment_id=$shipment->id;
$model->send_from=$shipment->send_from;
$model->send_to=$shipment->send_to;
$model->save(false);
}
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
'dataProvider'=>$dataProvider,
]);
}
}
I just try this way to insert data as above its works but the data inserted just last one or last CheckBox from the list. I tried to print the id that in foreach and there is more than one id.

That is beacuse you're reusing the same instace for each save() inside of foreach, so you're overwriting the same model over and over. You need to place $model = new Package() inside of foreach:
foreach($select as $id){
$shipment= shipment::findOne((int)$id);
$model = new Package();
$model->company_id=1;
$model->shipment_id=$shipment->id;
$model->send_from=$shipment->send_from;
$model->send_to=$shipment->send_to;
$model->save(false);
}
