Unserialize cart data not working Laravel - laravel

Question

I'm save my cart products as unserialized data from my cart session.
$order = new Order();
$order->cart = serialize($cart);
$order->code = strtoupper(str_random(15));
$order->user_id = Auth::user()->id;
$order->save();
now i need to unserialize the data to use it in my blade file, this is the function i'm using
$orders = Order::with('user')->findOrFail($order->id);
$orders->transform(function($order, $key){
$order->cart = unserialize($order->cart);
return $order;
});
dd($orders);
I'm getting this error
BadMethodCallException Call to undefined method App\Order::transform()
what seems to be the problem? and how can i unserialize my data;
any ideas ???

Answer 1

With findOrFail you retrieve just one instance of model, not a collection.
$orders = Order::with('user')->findOrFail($order->id);
Also what is $order->id you have your order model?
So
$order->load('user');
$order->cart = unserialize($order->cart);
Or do you want a collection then your code will work like this
$orders = Order::with('user')->get();
$orders->transform(function($order, $key) {
$order->cart = unserialize($order->cart);
return $order;
});

Answer 2

The problem is not about unserialize, it doesn't even get there. The problem seems to be related to an undefined method you are trying to use ($orders->transform).
Can you please provide the code in your Order class? Did you define the transform method there?
EDIT:
by using serialize you are kinda' missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries.
Also, many tests prove that json_encode is faster than serialize.
