laravel - 在laravel中调用null的成员函数getClientOriginalExtension（）？

问题描述

当我提交图像时，它显示以下错误：

在 null 上调用成员函数 getClientOriginalExtension()

我不知道，错误在哪里。

这是我的控制器，名为ProductController：

public function store(Request $request)
{
    $request->validate([
        'name' => 'required',
        'brand' => 'required',
        'detail' => 'required',
        'size' => 'required',
        'type' => 'required',
        'price' => 'required',
        'image' => 'required',
    ]);
    $image = $request->file('image');
    $new_name = rand().'.'.$image->getClientOriginalExtension();
    $image->move(public_path('images'), $new_name);
    $form_data = array(
        'image' => $new_name,
        'name' => $request->input('name'),
        'size' => $request->input('size'),
        'type' => $request->input('type'),
        'price' => $request->input('price'),
        'detail' => $request->input('detail'),
        'brand' => $request->input('brand'),
    );

    Product::create($form_data);
    return redirect()->route('product.index')->withSuccess('Done');
}

此行出现错误：$new_name = rand().'.'.$image->getClientOriginalExtension();

这是我提交图片的表单：

<form id="myForm" method="post" action="{{ route('product.store') }}">
                        @csrf
                        <div class="user-box">
