无法在Laravel 5.2中使用干预图像上传图像

Question

I am trying to upload an image using the tutorial here . I have followed the instructions exactly as in the video, but once I click on the submit button, it brings me back to the profile page, and the image is unchanged, nothing has changed in the database or uploaded to the folder designated.

Here is my routes.php :

Route::get('profile', 'UserController@showProfile');
Route::post('profile', 'UserController@updateAvatar');

Here is the blade file:

<div class="row">
   <div class="col-sm-4">
       <div class="text-align-center">
           <img class="img-circle" src="/uploads/avatars/{{ Auth::user()->avatar }}" alt="64x64" style="height: 112px; border-radius:50%;">
       </div>
       <br>
       <br>
       <div class="text-align-center">
          <form enctype="multipart/form-data" action="{{ url('/profile') }}" method="POST">
          <h5>Update Profile Image</h5>
          <input type="file" name="avatar">
          <input type="hidden" name="_token" value="{{ csrf_token() }}"> <br>          
          <input type="submit" class="pull-left btn btn-sm btn-primary">
          </form>
       </div>
</div>

Here is the controller:

 public function showProfile(){

        return view('profile', array('user' => Auth::user()));
    }

    public function updateAvatar(Request $request){
        //Handle the user upload of avatar
        if($request->hasFile('avatar')){
            $avatar = $request->file('avatar');
            $filename = time() . '.' . $avatar->getClientOriginalExtension();
            Image::make($avatar)->resize(200, 200)->save( public_path('/uploads/avatars/' . $filename ) );
            $user = Auth::user();
            $user->avatar = $filename;
            File::
            $user->save();
        }

        return view('profile', array('user' => Auth::user()));
    }

I have added a field avatar to the users table.

public function update_avatar(Request $request){

    // Handle the user upload of avatar
    if($request->hasFile('avatar')){
        $avatar = $request->file('avatar');
        $filename = time() . '.' . $avatar->getClientOriginalExtension();
        $avatar->move('/uploads/avatars', $filename);       
        $user = Auth::user();
        $user->avatar = $filename;
        $user->save();
    }

    return view('profile', array('user' => Auth::user()) );

}
