I want to store in a session array a shopping cart. I'm trying to do this:

class TestController extends Controller
{
    function add($id, Request $request) {
        if ($request->session()->missing('shopping_cart')) {
            $request->session()->put('shopping_cart', []);
        }

        $item = array(
            'id' => $id,
            'quntity'=> 1
        );

        $request->session()->push('shopping_cart', $item);
    }
}

Output:

[
  0 => [
    "id" => "12"
    "quantity" => 1
  ]
]

But when I call another time the function add() it replace the array like so:

[
  0 => [
    "id" => "20"
    "quantity" => 1
  ]
]

Desired output:

[
  0 => [
    "id" => "12"
    "quantity" => 1
  ]
  1 => [
    "id" => "20"
    "quantity" => 1
  ]
  2 => [
    "id" => "27"
    "quantity" => 1
  ]
]

It is probably because shopping_cart is an already defined key. So it will overwrite data with that key. The best thing you can do is create a unique item with the ID in that shopping_cart object. Something like;

    function add($id, Request $request) {
        $shoppingCartKey = 'shopping_cart.'+ $id;
        $shoppingCartData = array(
            'quantity'=> 1
        );

        if ($request->session()->missing($shoppingCartKey)) {
            $request->session()->put($shoppingCartKey, []);
        }


        $request->session()->push($shoppingCartKey, $shoppingCartData);
    }

Now you're also able to get/pull data from the session based on the shopping_cart ID/key

This will get you sorted as long as you carry the cart id to every function you wish to work with the cart. below is the add product to cart session

    public function addItem($id)
    {
        $post = Post::find($id);

        if(!$post) {

            abort(404);

        }

        $cart = session()->get('cart');

        // if cart is empty then this the first product
        if(!$cart) {

            $cart = [
                $id => [
                    "name"          => $post->product_name,
                    "quantity"      => 1,
                    "price"         => $post->price,
                ]
            ];

            session()->put('cart', $cart);

            return redirect()->back()->with('toast_success', 'Product added to cart successfully!');
        }

        // if cart not empty then check if this product exist then increment quantity
        if(isset($cart[$id])) {

            $cart[$id]['quantity']++;

            session()->put('cart', $cart);

            return redirect()->back()->with('toast_success', 'Product added to cart successfully!');

        }

        // if item not exist in cart then add to cart with quantity = 1
        $cart[$id] = [
            "name"          => $post->product_name,
            "quantity"      => 1,
            "price"         => $post->price,
        ];

        session()->put('cart', $cart);

        return redirect()->back()->with('toast_success', 'Product added !!');
    }
