Insert multi record to database with yii2 - yii

Question

I want to insert many record to database in one action.
In this controller I used foreach for insert to database, but just the last record inserts to database, I don't know why. I want to insert all the record to database.
My controller:
if (isset($_POST['month'])) {
$name = $_POST['month'];
$price = $_POST['Request'];
$i = 0;
foreach ($name as $month) {
$model->month = $month;
$model->price = $price['price'];
$model->save(false);
$i++;
}
$pay_info = [
'cost' => $price['price'],
'title' => 'title'];
return $this->render('payment', ['pay_info' => $pay_info]);
}

Answer 1

A simple way is based on the fact you should create a new model in you foreach for each instance you want save
(your controller code is not complete so i can't know your model )
if (isset($_POST['month'])) {
$name = $_POST['month'];
$price = $_POST['Request'];
$i = 0;
foreach ($name as $month) {
$model = new YourModel(); /* here */
$model->month = $month;
$model->price = $price['price'];
$model->save(false);
$i++;
}
$pay_info = [
'cost' => $price['price'],
'title' => 'title'];
return $this->render('payment', ['pay_info' => $pay_info]);
}
but i siggest to explore also the batchInsert command http://www.yiiframework.com/doc-2.0/yii-db-command.html#batchInsert()-detail
For batch insert you can build an asscociative array with month and price eg:
$my_array= [
['January', 30],
['Febrary', 20],
['March', 25],
]
\Yii::$app->db->createCommand()->
batchInsert('Your_table_name', ['month', 'price'],$my_array)->execute();
