在laravel 4中上傳文件

Question

我已經在Laravel 4的控制器和路由文件中對此進行了編碼，並遇到了諸如“在非對象上調用成員函數move（）”之類的錯誤，並且

     "Call to a member function getClientOriginalName() on a non-object"

控制器：

class AuthorsController extends BaseController{
    public $restful = true;


    public function post_files()
    {

         $input = Input::all();
        $rules = array(
             'file' => 'image|mime:jpg,gif,png|max:3000',
        );

         $validation = Validator::make($input, $rules);

         if ($validation->fails())
         {
           return Response::make($validation->errors->first(), 400);
         }


        $file = Input::file('file'); // your file upload input field in the form should be named 'file'

        $destinationPath = 'public/uploads/'.str_random(8);
        // $filename = $file->getClientOriginalName();
        $filename = $file['name'];
        //$extension =$file->getClientOriginalExtension(); //if you need extension of the file
        $uploadSuccess = Input::file('file')->move($destinationPath, $filename);



        if( $uploadSuccess ) {
           return Response::json('success', 200); // or do a redirect with some message that file was uploaded
        } else {
           return Response::json('error', 400);
        }
    }

}

路線：

路線:: post（'post_files'，'AuthorsController @ post_files'）;

Answer 1

您的表格是什么樣的？

在Laravel 4中，如果要上傳文件，則需要打開文件表單

{{  Form::open(array('url' => 'my/path', 'files' => true)) }}

打開文件表單后，方法getClientOriginalName（）將起作用。

還要確保您輸入的是文件

{{ Form::file('file') }}
