Laravel Users表更新

the image show is my Users table structure in Laravel 5.2, Yellow marks indicate that this rows are containing data when I sign up from Laravel Default Authentication. Now I want to update empty rows. I have created profile.blade.php for using Post method and userController is coded with:

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;

use App\Http\Requests;
use Auth;
use Image;

class UsersController extends Controller
{
    public function getsignup()
    {
        return view('edit_profile', array('user' => Auth::user()));
    }

    public function postsignup(Request $request)
    {
        //dd($request->all());         

        if($request->hasFile('img')){
            $img = $request->file('img');
            $file_name = time() . '.' . $img->getClientOriginalExtension();
            Image::make($img)->resize(300, 300)->save( public_path('/uploads/images/' . $file_name ));

        }
        $user = Auth::User();
        $user->img =$file_name;
        $user->city = 'city';
        $user->country = 'country';
        $user->company_name = 'comapany_name';
        $user->street_name = 'street_name';
        $user->apartment = 'apartment';
        $user->village = 'village';
        $user->city = 'city';
        $user->postal_code = 'postal_code';
        $user->post_office = 'post_office';
        $user->nid = 'nid';
        $user->phone = 'phone';

        $user->save();
        return back()->with('message', 'Successfully Registered!');
    }    
    }

enter image description here But its only taking such value like 'city', 'company_name', etc. As i provided second image. I got stuck. I am new in Laravel. I hope you have a solution for me. Thanks In advance.

why are the field updates inside the if condition? this way it will only update if an image was uploaded

try this

public function postsignup(Request $request)
    {
        //dd($request->all());


        if($request->hasFile('img')){
            $img = $request->file('img');
            $file_name = time() . '.' . $img->getClientOriginalExtension();
            Image::make($img)->resize(300, 300)->save( public_path('/uploads/images/' . $file_name ));
            $user->img =$file_name;
            }


        $user = Auth::User();
        $user->city = $s;
        $user->country = 'country';
        $user->company_name = 'comapany_name';
        $user->street_name = 'street_name';
        $user->apartment = 'apartment';
        $user->village = 'village';
        $user->city = 'city';
        $user->img = isset($user->img)? $user->img : '';
        $user->postal_code = 'postal_code';
        $user->post_office = 'post_office';
        $user->nid = 'nid';
        $user->phone = '

        $user->save();
        return back()->with('message', 'Successfully Registered!');
    }

This perfectly works:

public function postsignup(Request $request)
    {
        //dd($request->all());


       if($request->hasFile('img')){
            $img = $request->file('img');
            $file_name = time() . '.' . $img->getClientOriginalExtension();
            Image::make($img)->resize(300, 300)->save( public_path('/uploads/images/' . $file_name ));

        }
        $user = Auth::User();
        $user->img =$file_name;
        $user->city = $request->city;
        $user->country = $request->country;
        $user->company_name = $request->comapany_name;
        $user->street_name = $request->street_name;
        $user->apartment = $request->apartment;
        $user->village = $request->village;
        $user->postal_code =$request ->postal_code;
        $user->post_office =$request->post_office;
        $user->nid = $request->nid;
        $user->phone = $request->phone;

        $user->save();
        return back()->with('message', 'Successfully Registered!');
    }
