Bad Request (#400) Missing required parameters: id - php

Question

My Controller:
public function actionCreate()
{
$model = new SuratMasuk(['scenario' => 'create']);
if ($model->load(Yii::$app->request->post()))
{
try
{
$picture = UploadedFile::getInstance($model, 'imageFile');
$model->imageFile = $_POST['SuratMasuk']['id_suratmasuk'].'.'.$picture->extension;
if($model->save())
{
$picture->saveAs('uploads/' . $model->id_suratmasuk.'.'.$picture->extension);
Yii::$app->getSession()->setFlash('success','Data saved!');
return $this->redirect(['view','id'=>$model->id_suratmasuk]);
}
else
{
Yii::$app->getSession()->setFlash('error','Data not saved!');
return $this->render('create', [
'model' => $model,
]);
}
}
catch(Exception $e)
{
Yii::$app->getSession()->setFlash('error',"{$e->getMessage()}");
}
}
else
{
return $this->render('create', [
'model' => $model,
]);
}
}
getting this error message when i try to save my post. and it just uploads the text not images. i've tried $model->save(false); but not working
i'm newbie on yii, i'll appreciate your help

I guess this is because you try to pass id here:
return $this->redirect(['view', 'id' => $model->id_suratmasuk]);
and since actionView almost for sure requires id as parameter you get this error because $model->id_suratmasuk is empty.
You need to set proper rules() in SuratMasuk model.
Do not use POST variables directly, this is asking for being hacked.
Do not use save(false) if you need to save anything that comes from user (validation is a must!).
Add rules() for all attributes so there will be no surprises like with this id_suratmasuk being empty.
Check result of saveAs() on UploadedFile instance - this can go false as well.
