            <b>The card is empty</b> <a href="/products">Shopping now</a>
        @else
            <table class="table table-condensed table-bordered">
                <thead>
                    <tr>
                        <th>item id</th>
                        ....
                    </tr>
                </thead>
                <tbody>
                    {!! Form::open(["url"=>"/pay"]) !!}
                    <?php $i = 0; $totalCart_price = 0; ?>
                    @foreach($cart_total_items as $item)
                        <tr>
                            <td>{{ $item['id'] }}</td>
                            ....
                            <td>
                                {!! Form::open(["url"=>"/my-cart/".$item['id'], "method"=>"DELETE", "style"=>"display: inline"]) !!}
                                    <button type="submit" class="btn btn-danger" aria-label="Left Align">
                                        <span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
                                    </button>
                                {!! Form::close() !!}
                            </td>
                        </tr>
                        <?php $i++; $totalCart_price += Cart::get($item['id'])->getPriceSum(); ?>
                    @endforeach         
                </tbody>
            </table>
            <b>Total price: ${{ $totalCart_price }} {{ Form::hidden("total_price", $totalCart_price) }}</b>
            <br><br>
            {!! Form::submit('check out (paypal)', ["class"=>"btn btn-primary"]) !!}
            {!! Form::close() !!}
            <a href="/my-cart/clear" class="btn btn-danger">Clear cart</a>
        @endif
    </div>
@stop

问题：我可以删除任何项目，但在点击检查期间没有任何反应，但是当我删除clear item form时，请检查运行是否成功。

我想运行两个操作，我该如何解决？
感谢

您可以在页面中包含多个表单，但不应嵌套它们正如html5 working draft中所述：

4.10.3表单元素

内容模型：

流内容，但没有表单元素后代。

据我所知，form只是html标签，可用于一次向服务器发送一组数据（数组）。
在你的情况下，你最好的选择是使用ajax查询。（虽然它会使我们的页面javascript依赖）
或者，正如我所观察到的，你可以将下面的两个形式分开：

@extends('master')

@section('content')
    <div class="container">
        @if(Cart::isEmpty())
            <b>The card is empty</b> <a href="/products">Shopping now</a>
        @else
            <table class="table table-condensed table-bordered">
                <thead>
                    <tr>
                        <th>item id</th>
                        ....
                    </tr>
                </thead>
                <tbody>
                    <<!-- Remove the Form tag from here and insert it below -->>
                    <?php $i = 0; $totalCart_price = 0; ?>
                    @foreach($cart_total_items as $item)
                        <tr>
                            <td>{{ $item['id'] }}</td>
                            ....
                            <td>
                                {!! Form::open(["url"=>"/my-cart/".$item['id'], "method"=>"DELETE", "style"=>"display: inline"]) !!}
                                    <button type="submit" class="btn btn-danger" aria-label="Left Align">
                                        <span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
                                    </button>
                                {!! Form::close() !!}
                            </td>
                        </tr>
                        <?php $i++; $totalCart_price += Cart::get($item['id'])->getPriceSum(); ?>
                    @endforeach         
                </tbody>
            </table>
            <<!-- Remove the Form tag from above and insert it below -->>
            {!! Form::open(["url"=>"/pay"]) !!}
            <b>Total price: ${{ $totalCart_price }} {{ Form::hidden("total_price", $totalCart_price) }}</b>
            <br><br>
            {!! Form::submit('check out (paypal)', ["class"=>"btn btn-primary"]) !!}
            {!! Form::close() !!}
            <a href="/my-cart/clear" class="btn btn-danger">Clear cart</a>
        @endif
    </div>
@stop
