Answer 1

I dont see $model->companytype = 4 in your update action. Can you add it to your update action and check. So your update action should look like:
public function actionUpdate($id)
{
if(Yii::$app->user->can('update-company'))
{
$model = $this->findModel($id);
$model->companytype = 4;
if ($model->load(Yii::$app->request->post()) )
{
$model->updatedat = date('Y-m-d h:m:s');
$ro = $model->relationoption;
if($ro == 'fixed')
{
$commaList = implode(', ', $model->relation);
$model->relation = $commaList;
}
$model->save();
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('update', [
'model' => $model,
]);
}
else
{
throw new ForbiddenHttpException;
}
}
