How do I update new collection values? - php

Question

I need a way to update a collection that I am getting from the html form.
I have an array of
Product ids:
array:3 [
0 => "1"
1 => "2"
2 => "3"
]
Product quantity:
array:3 [
0 => "15"
1 => "5"
2 => "7"
]
Product Price:
array:3 [
0 => "12.00"
1 => "2.50"
2 => "4.00"
]
I am storing/saving the values to the database with something like this:
$product_ids = $request->get('product_ids');
$product_prices = $request->get('product_prices');
$product_quantities = $request->get('product_quantities');
$product_descriptions = $request->get('product_descriptions');
for ($i = 0; $i < sizeof($product_ids); $i++) {
$item = new Order_item;
$item->order_id = $order->id;
$item->product_id = $product_ids[$i];
$item->unit_price = $product_prices[$i];
$item->description = $product_descriptions[$i];
$item->quantity = $product_quantities[$i];
$item->save();
}

Answer 1

You can find the record based on id and then save the changed data:
$flight = App\Flight::find(1);
$flight->name = 'New Flight Name';
$flight->save();
From https://laravel.com/docs/7.x/eloquent#updates
If you're using order_id as the key, then use a where() statement with first():
$order = App\Order_item::where('order_id', 1)->first();

Answer 2

I fixed the issue with something like this:
$product_ids = $request->get('product_ids');
$product_prices = $request->get('product_prices');
$product_quantities = $request->get('product_quantities');
$product_descriptions = $request->get('product_descriptions');
Fetched the values using $request->get.
And updated the values using a for loop.
for ($i = 0; $i < sizeof($product_ids); $i++) {
Order_item::where('order_id', $id)
->where('product_id', $i + 1)->update(
[ 'quantity' => $product_quantities[$i],
'unit_price' => $product_prices[$i],
'description' => $product_descriptions[$i],
]);
