Laravel 图片上传不保存到公共文件夹

Question

我正在为这个图像上传系统而苦苦挣扎。 它应该上传一张将附加到帖子的图片（每个帖子都有一张图片）。

一切似乎都正常，问题是当我检查数据库的图像路径时，我看到一个随机临时文件的路径，并且图像甚至没有上传到应用程序 public 内的正确文件夹文件夹。

检查以下逻辑：

PostController.php

public function store(Request $request)
{
    $post = new Post;

    $request->validate([
        'title' => 'required',
        'description' => 'required',
        'slug' => 'required',
        'message' => 'required',
        'user' => 'required',
        'post_image' => 'image|mimes:jpeg,png,jpg,gif|max:2048'
        ]);

        if ($request->has('post_image')) {
            $image = $request->file('post_image');
            $name = Str::slug($request->input('title')).'_'.time();
            $folder = '/uploads/images/';
            $filePath = $folder . $name. '.' . $image->getClientOriginalExtension();
            $this->uploadOne($image, $folder, 'public', $name);
            $post->post_image = Storage::url($filePath);;
        }

    Post::create($request->all());

    return \Redirect::to('admin')->with('success','Great! Post created successfully.');
}

上传特征.php

trait UploadTrait
{
    public function uploadOne(UploadedFile $uploadedFile, $folder = null, $disk = 'public', $filename = null)
    {
        $name = !is_null($filename) ? $filename : Str::random(25);

        $file = $uploadedFile->storeAs($folder, $name.'.'.$uploadedFile->getClientOriginalExtension(), $disk);

        return $file;
    }
}

Post.php（模型）

    class Post extends Model
{
    protected $fillable = [
        'title',
        'description',
        'slug',
        'message',
        'user',
        'post_image'
       ];


    public function getImageAttribute(){
        return $this->post_image;
    }

}

创建.blade.php

<form action="{{ route('blog.store') }}" method="POST" name="add_post" role="form" enctype="multipart/form-data">
{{ csrf_field() }}

<h1>New Post</h1>
<div role="separator" class="dropdown-divider"></div> 

<div class="form-row">
    <div class="form-group col-12 col-md-6">
      <label for="title">Post Title</label>
      <input type="text" autocomplete="off" class="form-control" id="title" name="title" placeholder="Your post title" required>
      <span class="text-danger">{{ $errors->first('title') }}</span>
    </div>

    <div class="form-group col-12 col-md-6">
        <label for="slug">Slug</label>
      <input type="text" autocomplete="off" class="form-control" id="slug" name="slug" placeholder="Write post slug" required>
      <span class="text-danger">{{ $errors->first('slug') }}</span>
    </div>
</div>

<div class="form-row">
    <div class="form-group col-12 col-md-12">
        <label for="description">Post Description</label>
      <textarea class="form-control" id="description" name="description" placeholder="Enter a small description for your post" required></textarea>
      <span class="text-danger">{{ $errors->first('description') }}</span>
    </div>


</div>


    <div class="badge badge-warning badge-pill">Message</div>
    <div role="separator" class="dropdown-divider"></div>

 <div class="form-row">
    <div class="form-group col-md-12">
        <textarea class="form-control" col="4" id="message" name="message"></textarea>
        <span class="text-danger">{{ $errors->first('message') }}</span>
    </div>

</div>

<input type="hidden" value="{{ Auth::user()->name }}" name="user">

<input id="post_image" type="file" class="form-control" name="post_image">



  <button type="submit" class="btn btn-warning btn-block">Create Post</button>

</form>

感谢您的帮助！

Answer 1

Laravel itself提供的功能可以直接使用

$image_path = Storage::disk('public')->putFile('folders/inside/public', $request->file('post_image'));

通知Storage::disk('public') 指定公用文件夹。

然后您可以使用$request['image_path'] = $image_path 更新您的请求数组并像现在一样保存它，或者您不能仍然使用您的$post = new Post; 并设置每个输入数据像$post->title = $request->title; 然后像$post->save(); 一样保存

Answer 2

您创建的帖子没有将图片路径保存在数据库中

$post = new Post; //here you have created an empty Post object
...
$post->post_image = Storage::url($filePath); //here you assigned the post_image to the empty object.

Post::create($request->all());// here you create a new POST object with the request data, which does not contain the post_image

谢谢大卫！我设法更正了保存到数据库的路径，但文件没有上传（即使数据库中的路径显示/uploads/images/something.png，当我检查文件夹时，图像不存在..甚至没有上传文件夹。这是我现在根据您的建议采用的方法：

public function store(Request $request)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
            'slug' => 'required',
            'message' => 'required',
            'user' => 'required',
            'post_image' => 'image|mimes:jpeg,png,jpg,gif|max:2048'
            ]);

            if ($request->has('post_image')) {
                $image = $request->file('post_image');
                $name = Str::slug($request->input('title')).'_'.time();
                $folder = '/uploads/images';
                $filePath = $folder . $name. '.' . $image->getClientOriginalExtension();
                $this->uploadOne($image, $folder, 'public', $name);
                $image_path = Storage::disk('public')->putFile('uploads/images', $request->file('post_image'));
                $request['image_path'] = $image_path;

            }

            $post = new Post;
            $post->title = $request->title;
            $post->description = $request->description;
            $post->slug = $request->slug;
            $post->message = $request->message;
            $post->user = $request->user;
            $post->post_image = $request->image_path;
            $post->save();

        return \Redirect::to('admin')->with('success','Great! Post created successfully.');
    }

Answer 4

表单输入

<form method="POST" enctype="multipart/form-data" action="/url">
     <input id="category_logo" type="file" class="form-control"  name="category_logo">...

控制器中的代码

$category = Category::find($id);
if($request->has('category_logo')) {
                $image = $request->file('category_logo');
                $category->category_logo = $image->getClientOriginalName();
                $image->move(public_path('img/logo'), $image->getClientOriginalName());
            }
            $category->save();
