Laravel 5.4 Bildaktualisierung funktioniert nicht

Question

Ich habe eine Laravel-Anwendung mit CRUD-Operationen und ein Problem mit der Aktualisierung des hochgeladenen Bildes. Jedes andere Feld wird aktualisiert. Ich kann nicht für das Leben von mir das Problem finden. Hier

ist der Code für den Controller:

public function update(Request $request, $id) 
{ 
    // Validate the data 
    $post = Post::find($id); 

    $this->validate($request, array(
      'title' => 'required|max:255', 
      'slug' => "required|alpha_dash|min:5|max:255|unique:posts,slug,$id", 
      'category_id' => 'required|integer', 
      'body' => 'required', 
      'featured_image' => 'image' 
     )); 

    // Save the data to the database 
    $post = Post::find($id); 

    $post->title = $request->input('title'); 
    $post->slug = $request->input('slug'); 
    $post->category_id = $request->input('category_id'); 
    $post->body = Purifier::clean($request->input('body')); 


    if ($request->hasFile('featured_img')) { 
     //add the new photo 
     $image = $request->file('featured_img'); 
     $filename = time() . '.' . $image->getClientOriginalExtension(); 
     $location = public_path('images/' . $filename); 
     Image::make($image)->resize(800, 400)->save($location); 
     $oldFilename = $post->image; 

     //update the database 
     $post->image = $filename; 

     //delete the old photo 
     Storage::delete($oldFilename); 

    } 

    $post->save(); 

    if (isset($request->tags)) { 
     $post->tags()->sync($request->tags); 
    } else { 
     $post->tags()->sync(array()); 
    } 


    // set flash data with success message 
    Session::flash('success', 'This post was successfully saved.'); 

    // redirect with flash data to posts.show 
    return redirect()->route('posts.show', $post->id); 
} 

Ich erhalte die Flash-Mitteilung zu sagen, dass die Post erfolgreich aktualisiert hat, aber das Bild ist immer noch die gleiche und hat nicht einmal hochgeladen zu die Datenbank. Ich benutze Laravel 5.4. Namen in Form nicht gerade Namen im Controller übereinstimmen -

{!! Form::model($post, ['route' => ['posts.update', $post -> id], 'method' => 'PUT', 'files' => true]) !!} 
<div class="col-md-8"> 


    <!-- form model binding --> 
    {{ Form::label('title', 'Title:') }} 
    {{ Form::text('title', null, ['class' => 'form-control input-lg']) }} 

    {{ Form::label('slug', 'Slug:', ['class' => 'form-spacing-top']) }} 
    {{ Form::text('slug', null, ['class' => 'form-control input-lg']) }} 

    {{ Form::label('category_id', 'Category:')}} 
    {{ Form::select('category_id', $categories, null, ['class' => 'form-control']) }} 

    {{ Form::label('tags', 'Tags:', ['class' => 'form-spacing-top']) }} 
    {{ Form::select('tags[]', $tags, null, ['class' => 'form-control select2-multi', 'multiple' => 'multiple']) }} 

    {{ Form::label('featured_image', 'Update Featured Image:', ['class' => 'form-spacing-top']) }} 
    {{ Form::file('featured_image')}} 

    {{ Form::label('body', 'Body:', ['class' => 'form-spacing-top']) }} 
    {{ form::textarea('body', null, ['class' => 'form-control']) }} 


</div> 
<div class="col-md-4"> 
    <div class="well"> 
     <div class="dl-horizontal"> 
      <dt>Created At:</dt> 
      <dd>{{date('M j, Y h:ia', strtotime($post->created_at)) }}</dd> 
     </div> 

     <div class="dl-horizontal"> 
      <dt>Last Updated:</dt> 
      <dd>{{date('M j, Y h:ia', strtotime($post->updated_at)) }}</dd> 
     </div> 

     <hr> 
     <div class="row"> 
      <div class="col-sm-6"> 
       {!! Html::linkRoute('posts.show', 'Cancel', array($post->id), array('class' => 'btn btn-danger btn-block')) !!} 
      </div> 
      <div class="col-sm-6"> 

       {{ form::submit('Save Changes', ['class' => 'btn btn-success btn-block']) }} 
      </div> 
     </div> 
    </div> 
</div> 

{!! Form::close() !!}
