Session in laravel - laravel

Question

class ControlController extends Controller
{
public function anyadirCarrito($id, $quan) {
$productoCarrito = (object)array(
'id' =>$id,
'cantidad' => $quan,
);
\Session::push('cart', $productoCarrito);
return \Session::get('cart');
}
}
I'm trying to call this function to store data, but every time I call it, it overwrites the data, I want it to store it next to the other one, but it overwrites it. How can I store it with the other one? And if I give him an id, how can I erase it?

Answer 1

The Laravel Session operates on a key/value basis. Therefore, when you push another item to the key cart, you are overwriting the same key to which you pushed the previous value.
If you want to maintain a cart, with all the products you've added, you'd first need to retrieve the value, and append the new product. For example:
public function addProduct($id, $quantity) {
// Get cart from session
$cart = session('cart', []);
// Increment existing product quantity, or add product to cart
if (array_key_exists($id, $cart)) {
$cart[$id]->quantity += $quantity;
} else {
$cart[$id] = (object) compact('id', 'quantity');
}
// Set cart in session
session(compact('cart'));
return $cart;
}
public function removeProduct($id) {
// Get cart from session
$cart = session('cart', []);
// Remove product from cart
unset($cart[$id]);
// Set cart in session
session(compact('cart'));
return $cart;
}
