Level 24

when i pass third parameter $qty in my add function

Where is your third parameter? public function add($item, $id)

Level 1

@ouhare i need to ask this is default function, and its working fine but when pass dynamic quantity then this happen.

This is my controller function when i add a quantity: i have pass the dynamic value when it works instead of 2(for now i just add to explain you when i add more then once.)

$cart->add($product, $product->id, 2);

My cart model function where i add product to cart

public function add($item, $id, $qty){
        $storedItem = ['qty' => $qty, 'price' => $item->price, '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;
    }

then this happen

Cart {#308 ▼
  +items: array:1 [▼
    1 => array:3 [▼
      "qty" => 3
      "price" => 136
      "item" => Product {#297 ▶}
    ]
  ]
  +totalQty: 2
  +totalPrice: 68
}

which is wrong

Level 1

I would start again. and think it through properly.

Why must price be 102?

oh, and don't mention specific people in your question because everyone else will not bother to answer

Level 1

Yes sure @Snapey . Please help in the above code. I want to fixed the every others product with 1 quantity at a time but when i add the product via search page i need dynamic. So in this 2nd case it mess with calculation and quantity issue.

Level 122

because the code is rubbish. Honestly, it would be better to start again.

Level 1

would you please help me to do this. i need a quantity if some one not chose it will default 1 and if some one select it will be that selected quantity. But if need same array of cart as i already do a lot of code.

@tehseen What happen if your $item already exists in your $this->items array ? You can set $qtywith any number you want, it will pick up the quantity of $this->items[$id].... I guess

Level 1

when a item already exist in my session(cart). with default setting with out qty parameter it add the product (if its same as already exits it increment if not add another product in cart) this works fine.

But if i add the dynamic quantity it mess up with orders quantity and total quantity and price.

public function add($item, $id, $qty=1)
{
    $storedItem = ['qty' => 0, 'price' => $item->price, 'item' => $item];
    if($this->items) {
        if(array_key_exists($id, $this->items)) {
            $storedItem = $this->items[$id];
        }
    }
    $storedItem['qty'] += $qty;
    $storedItem['price'] = $item->price * $storedItem['qty'];
    $this->items[$id] = $storedItem;
    $this->totalQty += $qty;
    $this->totalPrice += ($item->price * $qty);
}
