Laravel session - session

Question

I have done projects laravel shopping cart when clicking on the product detail page will open and click the add to cart sends the id to CartController # index. I then access the database and retrieve product information and I put on the session. Then I bought other products but my older products lost in session when I turn the page. Who can help me thanks

Answer 1

Probably you don't add this to existed array in session, but replace it.
Should do it this way:
$products = Session::get('products', array()); // get existed products or empty array
$products[] = $newProduct; // add new product to list
Session::put('products', $products); // put all products to session

Answer 2

this is my code for cart
public function addItem($ids,Request $request){
$data = Product::find($ids)->toArray();
$name =$data['name'];
$price = $data['price'];
$cart = $request->session()->get('cart');
if($cart==null){
$cart['quantity'][$ids] = 1;
$cart['price'][$ids] = $price;
$cart['name'][$ids] = $name;
$request->session()->put('cart', $cart);
}else{
if(array_key_exists($ids,$cart['quantity'])){
$cart['quantity'][$ids] += 1;
$cart['price'][$ids] = $price * $cart['quantity'][$ids];
$cart['name'][$ids] = $name;
}else{
$cart['quantity'][$ids] = 1;
$cart['price'][$ids] = $price;
$cart['name'][$ids] = $name;
}
$request->session()->put('cart', $cart);
}
}
