Laravel 无法保存照片

Question

我有下面的功能代码，但它不会将照片保存在数据库或文件路径中。

代码

public function store(Request $request)
    {
        $this->validate($request, array(
            'name' => 'required',
            'price' => 'required|numeric',
            'type_id' => 'required|numeric',
            'photo' => 'required',
        ));
        $item = new Menu;
        $item->name = $request->input('name');
        $item->price = $request->input('price');
        $item->type_id = $request->input('type_id');
        if ($request->hasFile('photo')) {
          $photo = $request->file('photo');
          $filename = 'MenuItem' . '-' . time() . '.' . $photo->getClientOriginalExtension();
          $location = public_path('images/'. $filename);
          Image::make($photo)->resize(500, 500)->save($location);
          $item->photo = $filename;
        }
        $item->save();
        Session::flash('success', 'Menu Item Saved Successfully.');
        return redirect()->back();
}

dd($request->all()); 以上代码

array:5 [▼
  "_token" => "awAvc7F8lOv9vKkfwyiTFj7jnQGszv8xjLQxcwRH"
  "name" => "test"
  "price" => "100"
  "photo" => "air putih.jpg"
  "type_id" => "1"
]

有什么想法吗？

更新

根据下面的Nabil Farhan 答案，我忘记了enctype="multipart/form-data"，但现在我明白了

Intervention \ Image \ Exception \ NotReadableException
Unable to find file ().

仍然无法保存我的照片。

更新 2

我再次dd了我的请求，现在添加enctype="multipart/form-data"之后变得奇怪了：

array:5 [▼
  "_token" => "awAvc7F8lOv9vKkfwyiTFj7jnQGszv8xjLQxcwRH"
  "name" => "kerupuk"
  "price" => "2000"
  "type_id" => "3"
  "photo" => UploadedFile {#805 ▼
    -test: false
    -originalName: "kerupuk.jpg"
    -mimeType: "image/jpeg"
    -error: 0
    #hashName: null
    path: "C:\Windows\Temp"
    filename: "phpB195.tmp"
    basename: "phpB195.tmp"
    pathname: "C:\Windows\Temp\phpB195.tmp"
    extension: "tmp"
    realPath: false
    aTime: 2019-02-12 04:57:39
    mTime: 2019-02-12 04:57:39
    cTime: 2019-02-12 04:57:39
    inode: 0
    size: 43933
    perms: 0100666
    owner: 0
    group: 0
    type: "file"
    writable: true
    readable: true
    executable: false
    file: true
    dir: false
    link: false
    linkTarget: "C:\Windows\Temp\phpB195.tmp"
  }
]

为什么我的照片字段会变成这样？！

无论如何，这是我在刀片中的形式：

{{ Form::open(array('route' => 'menus.store', 'files' => true)) }}
  <div class="row">
    <div class="col-md-12">
      <h5>Name</h5>
      {{ Form::text('name', null, array('class' => 'form-control')) }}
    </div>
    <div class="col-md-12">
      <h5>Price</h5>
      {{ Form::number('price', null, array('class' => 'form-control')) }}
    </div>
    <div class="col-md-12">
      <h5>Photo</h5>
      {{ Form::file('photo', array('class' => 'form-control', 'id' => 'photo')) }}
    </div>
    <div class="col-md-12">
        <h5>Type</h5>
        <select name="type_id" id="type_id" class="form-control">
            <option value="">-- Select --</option>
            @foreach($types as $type)
            <option value="{{$type->id}}">{{$type->name}}</option>
            @endforeach
        </select>
    </div>
    <div class="col-md-12 mt-2">
      {{ Form::submit('Save', array('class' => 'btn btn-primary')) }}
    </div>
  </div>
{{ Form::close() }}

Answer 1

"photo" => "air putih.jpg" 不应是字符串。它应该有一些关于文件的更多信息。

我认为问题出在您的刀片文件中。请检查您是否在表单标签中使用了enctype='multipart/form-data'。

编辑

改变这个

Image::make($photo)->resize(500, 500)->save($location);

到这里

Image::make($photo->getRealPath())->resize(500, 500)->save($location);

Answer 2

尝试改变这一行

Image::make($photo)->resize(500, 500)->save($location);


Image::make($photo->getRealPath())->resize('200','200')->save($location);

你的真实路径是错误的检查配置

Answer 3

你应该试试这个：

你的视图文件是这样的：

{!! Form::open(['route' => 'menus.store', 'class' => 'form-horizontal', 'role' => 'form', 'method' => 'post','files'=>true]) !!}
  <div class="row">
    <div class="col-md-12">
      <h5>Name</h5>
      {{ Form::text('name', null, array('class' => 'form-control')) }}
    </div>
    <div class="col-md-12">
      <h5>Price</h5>
      {{ Form::number('price', null, array('class' => 'form-control')) }}
    </div>
    <div class="col-md-12">
      <h5>Photo</h5>
      {{ Form::file('photo', array('class' => 'form-control', 'id' => 'photo')) }}
    </div>
    <div class="col-md-12">
        <h5>Type</h5>
        <select name="type_id" id="type_id" class="form-control">
            <option value="">-- Select --</option>
            @foreach($types as $type)
            <option value="{{$type->id}}">{{$type->name}}</option>
            @endforeach
        </select>
    </div>
    <div class="col-md-12 mt-2">
      {{ Form::submit('Save', array('class' => 'btn btn-primary')) }}
    </div>
  </div>
{{ Form::close() }}

您的控制器功能如下：

use Input;

public function store(Request $request)
    {
        $this->validate($request, array(
            'name' => 'required',
            'price' => 'required|numeric',
            'type_id' => 'required|numeric',
            'photo' => 'required',
        ));
        $item = new Menu;
        $item->name = $request->input('name');
        $item->price = $request->input('price');
        $item->type_id = $request->input('type_id');
        if ($request->hasFile('photo')) {
          $photo = Input::file('photo');
          $filename = 'MenuItem' . '-' . time() . '.' . $photo->getClientOriginalExtension();
          $location = public_path('images/'. $filename);
          $img = Image::make($photo->getRealPath());
          $img->resize(500, 500, function ($constraint) {
            $constraint->aspectRatio();
          })->save($location);
          $item->photo = $filename;
        }
        $item->save();
        Session::flash('success', 'Menu Item Saved Successfully.');
        return redirect()->back();
}
