For the file helper you should use unescaped rendering:
对于文件助手，您应该使用未转义的渲染：
{!! Form::file('stock_image') !!}
{!! Form::file('stock_image') !!}
If you want to upload multiple files you just have to use multiple input fields.
如果您想上传多个文件，您只需使用多个输入字段。
{!! Form::file('stock_image_1') !!}
{!! Form::file('stock_image_2') !!}
{!! Form::file('stock_image_3') !!}
If you want them in an array you can use the following syntax:
如果您希望它们在数组中，您可以使用以下语法：
{!! Form::file('stock_image[]') !!}
{!! Form::file('stock_image[]') !!}
{!! Form::file('stock_image[]') !!}
If you want to process the last one you can do the following:
如果要处理最后一个，可以执行以下操作：
An other tip: You can use the 'files' => trueoption for the Form::open()method instead of manually setting the enctype. It's a helper option.
另一个提示：您可以使用'files' => true该Form::open()方法的选项，而不是手动设置 enctype。这是一个辅助选项。
