I am using laravel sessions to store cart information on the web browser but I am getting this error "Trying to get property of a non object" when am testing. Any insights? the first snippet is controller then my model.I am using two foreach to retrieve the product information then display them on a modal where a user can now add to cart.
public function addtoCart(Request $request, $id){ $product = Product::find($id); $oldCart = Session::has('cart') ? Session::get('cart') : null; $cart = new Cart($oldCart); $cart->add($product, $product->$id); $request->session()->put('cart', $cart); dd($request->session()->get('cart')); return redirect()->back()->with('flash_message_success', 'Added Successfully'); }
<?php
namespace App;
class Cart
{
public $items = null;
public $totalQty = 0;
public $totalprice = 0;
public function _construct($oldCart){
if ($oldCart) {
$this->items = $oldCart->items;
$this->totalQty = $oldCart->totalQty;
$this->totalprice = $oldCart->totalprice;
}
}
public function add($item,$id){
$storedItem = ['qty'=>0, 'price' =>$item->price, 'item' ->$item->item];
if ($this->items) {
if (array_key_exists($id,$this->items)) {
$storedItem = $this->items[$id];
}
}
$storedItem['qty']++;
$storedItem['price'] = $item->price * $storedItem['qty'];
$this->items[$id] = $storedItem;
$this->totalQty++;
$this->totalprice += $item->price;
}
}
Product::find($id), the passed Id probably doesn't exists in your table. Make sure to pass an actual record.
