Question

我是Laravel的新手并且在开始使用真实文件时遇到了麻烦，而不是骗子。我想要做的是：我有存储功能 - 将图像从pc放入我的网站。但是当我试图进行编辑时所有崩溃 - 它不会对图像起作用：因为我正在使用提交功能我的PhotoController：

public function create()
{
  $categories = Category::all();
  return view('photo.create', compact('photo','categories'));
}
/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    $this->validate($request, [
   'title' => 'required|min:3',
   'image_url'=> 'required',
   'category_id' => 'required',
    ]);

     $photo = new Photo;
     if ($request->hasFile('image_url')) {
                     $file = $request->file('image_url');

                    $fileName = $request->image_url->store('');
                    $photo->image_url =  $fileName;
                 }

     $photo->title = $request->input('title');

     $photo->description = $request->input('description');
     $photo->category_id = $request->input('category_id');
     $photo->save();

     $request->session()->flash('create', $request->title. "Sekmingai sukurta");
     $path = $request->image_url->store('public');
     return redirect()->route('photos.index');

}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    return view('photos.index', compact('photo'));
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function edit($id)
{
  $photo = Photo::find($id );
  $categories = Category::all();

    return view('photo.edit', compact('photo', 'categories'));
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function submit(Request $request, $id)
{

  $photo = Photo::find($id);

  $photo->title = $request->input('title');
  $photo = new Photo;
  if ($request->hasFile('image_url')) {
                  $file = $request->file('image_url');

                 $fileName = $request->image_url->store('');
                 $photo->image_url =  $fileName;
              }

  $photo->description = $request->input('description');
  $photo->category_id = $request->input('category_id');

  $photo->update();

  $request->session()->flash('update', $request->title. "Sekmingai papildyta");
  $path = $request->image_url->store('public');
  return redirect()->route('photo.edit', $photo->id);

}

当我尝试编辑文件并上传新照片时 - 我收到错误：

＆＃34;在字符串＆＃34;
上调用成员函数store（）

它显示错误在这一行：

$path = $request->image_url->store('public');

有人可以建议吗？谢谢

编辑不适用于文件上传
