Question

@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>
                    {!! 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，但在单击检出期间没有任何反应，但是当我删除 clear item form 时，检出运行成功。

我想运行两次操作，请问如何解决？
谢谢

一个页面中可以有多个表单，但它们不应嵌套。
如 html5 working draft 中给出的：

4.10.3 The form element

Content model:

Flow content, but with no form element descendants.

据我所知，表单只是 html 标签，可用于一次向服务器发送一组（数组）数据。
在你的情况下，你最好的选择是使用 ajax 查询。（尽管它会使我们的页面 javascript 依赖）
或者，正如我观察到的，您可以像下面这样将两种形式分开：

@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>
