        <td>{{ $row['quantity'] }}</td>

    </tr>
@endforeach

getting error:

Illegal string offset 'product_name'

Answer 1

$order is an object $row->product_name and not an array $row['product_name'].

@foreach ($order as $row)
    <tr>
        <td>{{ $row->product_name }}</td>
        <td>{{ $row->amount }}</td>
        <td>{{ $row->quantity }}</td>
    </tr>
@endforeach

Answer 2

It might be because of 'product_name' key is not exist in your array element. Before using it, check is that key exist in that array element with isset

@foreach ($order as $row)
        <tr>
            <td>{{ isset($row['product_name'])?$row['product_name']:'' }}</td>

        </tr> @endforeach
