Question

我尝试了一些代码来将图像存储在数据库中，但是它不起作用。所以我很困惑，因为我是Laravel的初学者。有人可以帮助我解决我的问题吗？

这是我目前正在做的事情：

// store image 
$this->validate($request, [ 'image' => 'image', ]);
if($request->hasFile('image')) {
    $image = $request->file('image');
    $filename = time() . '.' . $image->getClientOriginalExtension();
    Image:make($image)->resize(145, 170)->save(public_path('/images' . $filename));
    $image->save(); 
};

Answer 1

$image不是您的App\Image模型的实例，而是UploadedFile类的实例

Image类是用于图像的PHP类

如果您要存储路径的属性为path

，请尝试这种方式

// store image 
$this->validate($request, [ 'image' => 'image', ]);
if($request->hasFile('image')) {
    $image = $request->file('image');
    $filename = time() . '.' . $image->getClientOriginalExtension();
    Image::make($image)->resize(145, 170)->save(public_path('/images' . $filename));

    $imageInstance = new \App\Image();
    $imageInstance->path = '/images' . $filename;
    $imageInstance->save(); 
};

此示例显示了如何上传多张图片

//查看

 <form class="form-horizontal" action="{{ url('/picture-update') }}" method="post"  role="form" enctype="multipart/form-data">
                    {{ csrf_field() }}

                <div class="col-sm-4"><label>Profile picture: </label>
                 <div class="form-group">
                        <input type="file" name="filename[]"  required> 
                        <br>
                </div>

                    <button type="submit" class="btn btn-success btn-xs">Upload</button>

                </form>

//控制器

public function uploadAttachment(Request $request)
    {
         $this->validate($request, [
          'filename.*' => 'mimes:pdf,doc,docx,jpeg,jpg,gif,png,bmp|max:2048',


              //processing insert into attachment table

           if($request->hasfile('filename'))
                 {
                    foreach($request->file('filename') as $file)
                    {
                       $name=$file->getClientOriginalName();
                       $file->move(public_path().'/../../yourdomain.com/attachments_files', $name);

                       DB::table('tblstaffAttachment')->insert([
                       'filepath' => $name,
                       ]);

                    }
                 }


              return back()->with('message', 'File Uploaded!');

     }

//路线

Route::post('/picture-update','YourController@uploadAttachment');
