'multipart / form-data'无效

I'm using Laravel and trying to build a gallery, i'm testing the upload of a file but i when i attach a file and click submit i can't get a positive outcome using the test set up. The code is below

GalleryController

// Store Gallery
    public function store(Request $request){
            // Get Request Input
        $name = $request->input ('name');        
        $description = $request->input ('description', '');
        $cover_image = $request->input ('cover_image');
        $owner_id = 1;

        // Check Image Upload
        if($cover_image){
die ('YES');
        } else {
die ('NO');
        }
    }

The form is set up as follows

{!! Form::open(array('action' => 'GalleryController@store', 'enctype' => 'multipart/form-data')) !!}
              {!! Form::label ('name', 'Name') !!}
              {!! Form::text ('name', $value = null, $attributes = ['placeholder' => 'Gallery Name', 'name' => 'name']) !!}

            {!! Form::label ('description', 'Description') !!}
              {!! Form::text ('name', $value = null, $attributes = ['placeholder' => 'Gallery Description', 'name' => 'Description']) !!}

            {!! Form::label ('cover_image', 'Cover Image') !!}
            {!! Form::file('cover_image') !!}

            {!! Form::submit ('Submit', $attributes = ['class' => 'button']) !!}
            {!! Form::close() !!}

Any help is appreciated Thanks

Your form looks correct, it is likely your controller where you are retrieving the uploaded file.

As per the docs, to retrieve an uploaded file you should use $request->file():

 $request->file('cover_image');

That link to the docs above also goes on to explain how you can check the file properly and store the file.

//use input facades.

use File;
use Illuminate\Support\Facades\Input;

 public function store(Request $request){
        // Get Request Input
        $name = $request->input ('name');        
        $description = $request->input ('description', '');
        $cover_image = $request->input ('cover_image');
        $owner_id = 1;

        // Check Image Upload
        if(Input::hasFile('cover_image'){
           die ('YES');
        }
        else {
           die ('NO');
        }
  }
