过滤来自2列

Question

我的滤镜搜索有问题......我想从sum total_amount和unique_number获取数据......但它不起作用.....我将在Controller中显示我的函数过滤器代码.. ..

public function ifilter(Request $request)
    {
        $data = $request->all();

        $flag = 1;

        $title = 'Invoice Paid';

        $master = Master_lookup::where('type' , 'LIKE' , 'order_status')->select('name','id')->where('id', '=' , 9)->orWhere('id' , '=' , 10)->orWhere('id' , '=' , 11)->orWhere('id' , '=' , 12)->orWhere('id' , '=' , 13)->orWhere('id' , '=' , 14)->get();

        if (! empty($data)) 
        {
            $orders = Order::whereHas('user', function ($query) use ($data)
            {
                if(! empty($data['buyer']))
                {
                    $query->where('name' , 'LIKE' , '%'.$data['buyer'].'%');
                }
            })->whereHas('store' , function($query) use ($data)
            {
                if(! empty($data['store']))
                {
                    $query->where('name' , 'LIKE' , '%'.$data['store'].'%');
                }
            })->where(function($query) use($data)
            {
                if (! empty($data['number'])) 
                {
                    $query->where('number','LIKE','%'.$data['number'].'%');
                }
            })->where(function($query) use($data)
            {
                if (! empty($data['total-amount'])) 
                {
                    $query->where('total_amount', '=' , $data['total-amount'])->where('total_amount','=','total_amount+unique');
                }
            })->where(function($query) use($data)
            {
                if (! empty($data['total-transferred'])) 
                {
                    $query->where('proof_of_payment', '=' , $data['total-transferred']);

                }    
            })->where(function($query) use($data)
            {
                if (! empty($data['received-at'])) 
                {
                    $query->whereDate('received_at' , '=' , $data['received-at']);
                }
            })->where(function($query) use($data)
            {
                if (! empty($data['request-at'])) 
                {
                    $query->whereDate('request_payout_at', '=' , $data['request-at']);
                }
            })->whereHas('master' , function($query) use($data)
            {
                if (! empty($data['status'])) 
                {
                    $query->where('id' , '=' , $data['status']);
                }
            })->where('status', '=' , 10)
            ->with('user')
            ->paginate(10);    
            
            return view('orders.invoice-paid', compact('master' , 'orders' , 'title' , 'flag'));            
        }



    }

你可以看到我的$ data ['total-amount'] ...我想尝试总和2列...但它不起作用.....我搜索我的数据，没有任何显示...可以请帮助我......如果可以，请告诉我正确的代码......
