Question

我想将图片上传到服务器。创建视图页面是：

{!! Form::open(['url'=>'imagesupload','enctype'=>'multipart/form-data','method' => 'post']) !!}
{!! Form::file('image') !!}
{!! Form::submit('Submit',['class'=>'btn btn-primary form-control']) !!}
{!! Form::close() !!}

我的控制器代码是：

namespace App\Http\Controllers;
use Illuminate\Http\Request;
public function store(Request $request)
{

    dd($request['image']);
}

我的路线是：

Route::post('imagesupload','ImagesController@store');

上传图片时的页面：

UploadedFile {#208 ▼
-test: false
-originalName: "WIN_20160626_17_24_33_Pro.jpg"
-mimeType: "application/octet-stream"
-size: 0
-error: 1
path: ""
filename: ""
basename: ""
pathname: ""
extension: ""
realPath: "/var/www/html/public"
aTime: 1970-01-01 08:00:00
mTime: 1970-01-01 08:00:00
cTime: 1970-01-01 08:00:00
inode: false
size: false
perms: 00
owner: false
group: false
type: false
writable: false
readable: false
executable: false
file: false
dir: false
link: false
}

有错误。图像没有大小。希望有人能告诉我原因。谢谢！

Answer 1

我认为你遗漏了一些东西。你必须使用$ request-＆gt;文件（＆＃39; fieldname＆＃39;）才能访问文件。尝试dd（$ request-＆gt;文件（＆＃39;图像＆＃39;））;

在视图中

   {!! Form::open(array('url'=>'imagesupload','method'=>'POST', 'files'=>true)) !!}
    {!! Form::file('image') !!}
    <p class="errors">
    {!!$errors->first('image')!!}</p>
    @if(Session::has('error'))
    <p class="errors">{!! Session::get('error') !!}</p>
    @endif
    <div id="success"> </div>

    {!! Form::submit('Submit', array('class'=>'send-btn')) !!}
    {!! Form::close() !!}

控制器中的

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use Input;
use Validator;
use Redirect;
use Session;

public function store() {

// getting all of the post data
$file = array('image' => Input::file('image'));
// return $file;
 // setting up rules
$rules = array('image' => 'required',); //mimes:jpeg,bmp,png and for max size max:10000
// doing the validation, passing post data, rules and the messages

$validator = Validator::make($file, $rules);
if ($validator->fails()) {
// send back to the page with the input data and errors
 return Redirect::to('uploadprofilepicture')->withInput()->withErrors($validator);
 }
else {
                // checking file is valid.
                if (Input::file('image')->isValid()) {

                  $destinationPath = 'images/profile/'; // upload path
                  $extension = Input::file('image')->getClientOriginalExtension(); // getting image extension
                  $fileName = rand(11111,99999).'.'.$extension; 
// renameing image
 // return $fileName; 
Input::file('image')->move($destinationPath, $fileName); 
// uploading file to given path
// sending back with message
Session::flash('success', 'Upload successfully'); 
 }
 else {
 // sending back with error message.
  Session::flash('error', 'uploaded file is not valid');
  return Redirect::to('yourviewfile');
 }
}
}

创建一个包含属性'files'=＆gt; true的表单，以便上传文件

{!! Form::open(array('url'=>'imagesupload','method'=>'POST', 'files'=>true)) !!}

在请求中，您可以通过$request->filename
