对数组Laravel5.2上的成员函数getClientOriginalName()的调用

Question

我有问题，我正在编写编辑列表菜单的函数，当我试图更新文件图像时，我遇到了getClientOriginalName()中的错误

调用数组上的成员函数getClientOriginalName()

 @foreach($edits as $key => $value)
    <input type="hidden" value="{{ $key }}" name="key_edit[{{ $key }}]">

看来你是在尝试在集合上使用方法。您应该使用foreach()来迭代文件，或者如果您只有一个文件，请执行如下操作：

$name = $file[0]->getClientOriginalName();
