Question

完成这项工作所需的简单逻辑，我祈求专家的帮助。我现在正试图在我正在开发的竞价网站上实施限制，简单就是：用户不能多次竞价产品。如果用户再次点击该产品，系统会提示他提供一个回复页面，告知用户之前已对该产品进行过出价，

这是刀片形式：

  <p><h3>{!! ucfirst($product->productname) !!}</h3></p>

            @if(Auth::user()->id === $product->user_id)
                <p>Sorry, you posted this product, you cannot quote on it.</p>

            @else
            <p>{!! Form::label('Higest Price') !!}</p>
            <p>{!! Form::number('price', Input::old('price')) !!}</p>
            <p>{!! Form::textarea('comments', Input::old('comments')) !!}</p>
            <p>{!! Form::hidden('product_id', $product->id) !!}</p>
            <p>{!! Form::hidden('company_id', $product->company_id) !!}</p>
            <p>{!! Form::hidden('user_id', $product->user_id) !!}</p>

            <p>{!! Form::submit('ADD QUOTE') !!}</p>
        @endif
        {!! Form::close() !!}

这是控制器：

public function store(BiddingCommentRequest $biddingCommentRequest)
    {
        $biddingComments = new BiddingComments;
        $product_id = $biddingCommentRequest->product_id;
        $AuthUserBidder = Auth::user()->id;
        $bidderCommented = BiddingComments::all();

        if($biddingCommentRequest->isMethod('post')){
            foreach ($bidderCommented as $key => $commentedBidder) {
               if(!count($commentedBidder->id) > 0)
               {
                    $biddingComments->bidder_id  = $AuthUserBidder;
                    $biddingComments->product_id = $product_id;
                    $biddingComments->company_id = $biddingCommentRequest->company_id;
                    $biddingComments->user_id    = $biddingCommentRequest->user_id;
                    $biddingComments->comments   = $biddingCommentRequest->comments;
                    $biddingComments->price      = $biddingCommentRequest->price;
                    $biddingComments->save();
                     return redirect()->route('biddingCommentView', $product_id)->with('message', 'Your question has been posted.');
               }elseif(($AuthUserBidder == $commentedBidder->bidder_id) && ($product_id == $commentedBidder->product_id))
               {
                    return redirect()->route('productindex')->with('message', 'Your question has been posted.');
               }else
               {
                    $biddingComments->bidder_id  = $AuthUserBidder;
                    $biddingComments->product_id = $product_id;
                    $biddingComments->company_id = $biddingCommentRequest->company_id;
                    $biddingComments->user_id    = $biddingCommentRequest->user_id;
                    $biddingComments->comments   = $biddingCommentRequest->comments;
                    $biddingComments->price      = $biddingCommentRequest->price;
                    $biddingComments->save();
                     return redirect()->route('biddingCommentView', $product_id)->with('message', 'Your question has been posted.');
                }
            }
        }
    }

它没有添加限制。它允许用户一遍又一遍地继续引用产品。请帮助。

您的方法有很多问题，首先，我会在产品型号中选择canQuote方法，而不是直接在刀片中进行比较。

function canQuote($user_id) {
    return static::where('user_id', $user_id)->where('id', $this->attributes['id'])->count() === 0;
}

接下来在store方法中，不是调用all()并检查一个大型数据库可能出错的循环，为什么不在利用eloquent的力量之前添加另一个检查用户是否已注释的方法< / p>

允许用户使用laravel 5.1
