How to save data to database?

Question

Yii

I use the yii2-multiple-input widget, I don’t understand a little in the documentation how to save data in the database with multiple values
​​​​in the guide if you need everything to view the model and the whole picture
Implemented like this but in the end

$models = [new Custom()];
$request = Yii::$app->getRequest();

Model::loadMultiple($models, Yii::$app->request->post())) {
            $data = Yii::$app->request->post('Custom', []);
            foreach (array_keys($data) as $index) {
                $models[$index] = new Custom();
            }

Tried to add $models->save() and got error Call to a member function save() on array
And tried $models[$index]->save(); it does not save
Tried to display an error

if(!$model->save()){
                Yii::warning($models[$index]->getErrors());
                }

But it didn't work either. Requests come in the form
Custom[0][product]:Handles
Custom[0][number]:10
how to solve this problem?

Answer 1

// создаем на каждый набор данных в массиве модель
$data = Yii::$app->request->post('Custom', []);
$models = [new Custom()];
foreach (array_keys($data) as $index) {
    $models[$index] = new Custom();
}
// загружаем данные из запроса в массив созданных моделей
if (Model::loadMultiple($models, Yii::$app->request->post())) {
    foreach ($models as $model) {
        //сохраняем данные
        $model->save();
    }
}

Call to a member function save() on array

Says you are calling save() on an array, and only AR objects have a save() method. Apparently, you need to iterate over the array, it will contain objects, to which you can apply the save method
