更改付款状态按钮会出现错误“创建默认对象...”

Question

I'm trying to make 2 buttons with Mars as Paid and Mark as Unpaid values 1/0.

When I click on button I've got error:

Creating default object from empty value

What is wrong with the code? I know it can be write more 'intelligent'. Here is the controller

public function ordersPaidSubmit($orderId) {

$order = Order::where('order_id', $orderId)->first();
    if (!$order) {
        App::abort(404);
}
    $paid->paid = Input::get('paid');
    $order->save();

    return Redirect::to('/orders')->with('message', '');
}

And here is view buttons

{{ Form::open() }}
    @if($order->paid = 0)
        <button type="submit" class="btn btn-primary" name="paid" id="paid" value="1">Mark Order as Paid</button> 
    @else
            <button type="submit" class="btn btn-primary" name="paid" id="paid" value="0">Mark Order as Unpaid</button>
    @endif
{{ Form::close() }}

Answer 1

Seem like the problem is in your controller where you take paid value from the form. Try to replace:

$paid->paid

whit

$paid['paid']

On this line

$paid->paid = Input::get('paid');
