php – Laravel验证ErrorException – htmlentities()期望参数1为字符串,给定数组

所以我是laravel 5的新手,刚开始编写我自己的应用程序.

当我只调用invoices.create控制器的路由时,视图生成就好了.

当我从invoices.store控制器重定向到同一视图时,我收到以下错误消息.

我的控制器,看起来像这样.

我猜它与传递给控制器​​的参数相矛盾,看着消息.但我似乎无法找到什么错误以及如何解决它.

好的,所以我设法缩小了问题.它与数组有关,作为输入字段的名称,当我删除此表行时…错误消失了.
但是我该如何解决这个问题呢？

<tr>
    <td class="cell-width-5">{!! Form::text('items[amount][]', null, array('class'=>'form-control')) !!}</td>
    <td>{!! Form::text('items[description][]', null, array('class'=>'form-control')) !!}</td>
    <td class="cell-width-6">{!! Form::text('items[price][]', null, array('class'=>'form-control')) !!}</td>
    <td class="cell-width-5"></td>
    <td class="cell-width-12">{!! Form::text('items[vat][]', null, array('class'=>'form-control')) !!}</td>
    <td class="cell-center"><span class="glyphicon glyphicon-trash pointer" aria-hidden="true"></span></td>
</tr>

任何帮助表示赞赏！

解决方法:

编辑：这是Laravel的表单构建器的已知问题：https://github.com/laravel/framework/issues/2243

它会阻止您使用数组作为Form :: text()方法调用的name参数.我认为它与表单如何从HTML中的给定模型分配值有关.

我认为你将不得不为该部分编写基本的HTML表单.
