Yii2 Save multiple data in the db using foreach loop in actionCreate - arrays

Question

In my project I want to insert multiple rows of data at a single time using the foreach loop. I have a variable which has array of elements.
For instance if my array has say 3 different elements. I want to save all these 3 elements in the 3 different db table rows. I also have other columns which are same for all the 3 array elements.
I have put them inside foreach statement but only the 1st elements gets saved. Is there any method I can achieve this?
My code
public function actionCreate($prodID)
{
$model = new ProductlinesStorage();
if ($model->load(Yii::$app->request->post())) {
$productlineID = Productlines::find()->where(['area_id' => $model->productline_id, 'product_id' => $prodID])->all();
foreach ($productlineID as $singleProductlineID) {
$model->productline_id = $singleProductlineID->productline_id;
$model->user_id = Yii::$app->user->identity->user_id;
$model->isNewRecord = true;
$model->save();
}
return $this->redirect(['/product/storage?id='.$prodID]);
} else {
return $this->renderAjax('create', [
'model' => $model,
'prodID' => $prodID,
]);
}
}
Only the productline_id is different other columns will have same data for all the prdouctline_id.
Thank You!!!

You have only one model object, and you are saving only to it.
Try this:
public function actionCreate($prodID)
{
$model = new ProductlinesStorage();
if ($model->load(Yii::$app->request->post())) {
$productlineID = Productlines::find()->where(['area_id' => $model->productline_id, 'product_id' => $prodID])->all();
foreach ($productlineID as $singleProductlineID) {
$model = new ProductlinesStorage();
$model->productline_id = $singleProductlineID->productline_id;
$model->user_id = Yii::$app->user->identity->user_id;
$model->isNewRecord = true;
$model->save();
}
return $this->redirect(['/product/storage?id='.$prodID]);
} else {
return $this->renderAjax('create', [
'model' => $model,
'prodID' => $prodID,
]);
}
}

maybe you can modify my code
public function actionCreate()
{
$model = new SemesterPendek();
$model->user_id = \Yii::$app->user->identity->id;
$model->npm = \Yii::$app->user->identity->username;
$modelsNilai = [new Nilai];
if ($model->load(Yii::$app->request->post())){
$model->waktu_daftar = date('Y-m-d h:m:s');
$model->save();
$modelsNilai = Tabular::createMultiple(Nilai::classname());
Tabular::loadMultiple($modelsNilai, Yii::$app->request->post());
// validate all models
$valid = $model->validate();
$valid = Tabular::validateMultiple($modelsNilai) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
foreach ($modelsNilai as $indexTools =>$modelNilai) {
$modelNilai->id_sp = $model->id;
// $modelNilai->user_id = \Yii::$app->user->identity->id;
if (! ($flag = $modelNilai->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $model->id]);
}
} catch (Exception $e) {
$transaction->rollBack(); \Yii::$app->session->setFlash('error','gagal');
}
}
} else {
return $this->render('create', [
'model' => $model,
'modelsNilai' => (empty($modelsNilai)) ? [new Nilai] : $modelsNilai,
]);
}
}

You need to create a different object to save in different rows. For loop executes 3 times but every time same object is being updated. You can define new object and save each time. Below code will work
public function actionCreate($prodID)
{
$model = new ProductlinesStorage();
if ($model->load(Yii::$app->request->post())) {
$productlineID = Productlines::find()->where(['area_id' => $model->productline_id, 'product_id' => $prodID])->all();
foreach ($productlineID as $singleProductlineID) {
$model = new ProductlinesStorage();
$model->productline_id = $singleProductlineID->productline_id;
$model->user_id = Yii::$app->user->identity->user_id;
$model->isNewRecord = true;
$model->save();
}
return $this->redirect(['/product/storage?id='.$prodID]);
} else {
return $this->renderAjax('create', [
'model' => $model,
'prodID' => $prodID,
]);
}
}
