Hello,

I have table with form, here is code:

<tbody>
    @foreach($cart_products as $index => $cart_product)
        <tr>
            <td>{{ $cart_product->product->name }}</td>
            <td>
                {!! Form::open(['action' => ['CartsController@updateQuantity', $cart_product->id], 'class' => 'form-inline']) !!}
                <div class="input-group">
                    <div class="input-group">
                        {!! Form::text('quantity', $cart_product->quantity, ['class' => 'form-control']) !!}
                        <span class="input-group-btn">
                            {!! Form::submit('Set', ['class' => 'btn btn-success']) !!}
                        </span>
                    </div>
                </div>
                {!! Form::close() !!}
            </td>
        </tr>
    @endforeach
</tbody>

After I submit one of form with for example quantity value "10" and validation fails (because max available value is 5) all forms' inputs get value 10. Not just that form was submitted but all forms. How to prevent that?

To make more clear every thing before editing table is:
| Product 1 | [ 4 ] [SET] |
| Product 2 | [ 2 ] [SET] |
| Product 3 | [ 1 ] [SET] |
| Product 4 | [ 2 ] [SET] |

After validation failed tables looks like this:
| Product 1 | [ 10 ] [SET] |
| Product 2 | [ 10 ] [SET] |
| Product 3 | [ 10 ] [SET] |
| Product 4 | [ 10 ] [SET] |

In first row input I entered 10 and pressed first row "set" button.

Table should look like this:
| Product 1 | [ 10 ] [SET] |
| Product 2 | [ 2 ] [SET] |
| Product 3 | [ 1 ] [SET] |
| Product 4 | [ 2 ] [SET] |

UPDATE:

Here is validation code (it works fine):

	public function __construct(Factory $factory)
	{
		$cart_product = CartProduct::findOrFail(Route::input('cart_product'));
		$stock = $cart_product->product->stock;

		$factory->extend('stockAvailable', function ($attribute, $value, $parameters) use ($stock)
		{
			return (int)$stock >= (int)$value;
		},
			'Sorry, in stock we have only '.$stock.' pcs.'
		);
	}
