How To Solve This Image Insert

I'm creating a web site. And I have created a registration page. When I insert data, all the data successfully inserted into the database. But, images didn't insert into the database and not moved to the folder. How can I Fix this ??

Here is the AdminPanel.blade.php

<div class="panel-body">
 
  @if(session()->has('Msg'))
<h4 class="alert alert-success"> {{ session()->get('Msg') }} </h4>
@endif

@if(session()->has('OnlyImg'))
<h4 class="alert alert-success"> {{ session()->get('OnlyImg') }} </h4>
@endif  
    
    <form class="form-horizontal" method="POST" action="{{ route('adinsert') }}">

    {{ csrf_field() }}

  <div class="form-group">
    <label>Username : *</label>
    <input type="text" class="form-control" name="username" value="{{ old('username') }}" placeholder="Enter Your Username" required>
  </div>
    
    <div class="form-group">
    <label>Email : *</label>
    <input type="email" class="form-control" name="email" value="{{ old('email') }}" placeholder="Enter Your Username" required>
  </div>
  
  <div class="form-group">
    <label>Password : *</label>
    <input type="password" class="form-control" name="password" value="{{ old('password') }}" placeholder="Enter Your Password" required>
  </div>
  
  <div class="form-group">
    <label>Upload Profile Picture :</label>
    <input type="file" class="form-control-file" name="file_img" aria-describedby="fileHelp">
    <small id="fileHelp" class="form-text text-muted">If U Want , U Can Skip Upload A Profile Picture</small>
  </div>
  
  @section('btnName',"Insert") 
  <input type="submit" class="btn btn-primary" onclick="myFunction()" name="submit" value="@yield('btnName')">
                    
</form>
</div>

Here is the AdminPanelController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use Validator;
use Illuminate\Support\Facades\Input;

class AdminPanelController extends Controller
{
    public function index()
    {
      $data = User::all();
      //$data = login::orderBy('created_at', 'desc')->get();
      return view('AdminPanel', ['data' => $data]);
    }
    
public function adinsert(Request $request)
    {

        $username = $request->input('username');
        $email = $request->input('email');
        $password = $request->input('password');
        //$passen = bcrypt($password);
        
        $user = new User();
        $user->username = $username;
        $user->email = $email;
        $user->password = $password;
        
        $this->validate($request, [
            'email' => 'required'
        ]);
        
        if(Input::hasFile('file_img')){
            
            $file = Input::file('file_img');
            
            $rules = array(
                'file_img' => 'required|max:10000|mimes:doc,docx,jpeg,png,jpg'
            );
            
            $validator = Validator::make(Input::all(), $rules);
            
            if ($validator->fails()) {
                
                // redirect our user back with error messages
                
                // send back to the page with the input data and errors
                
                $request->session()->flash('OnlyImg', 'You Can Only Upload Images !!');
                return redirect('AdminPanel');
                
            }
            
            else if ($validator->passes()) {
                
                $fileimg = $file->getClientOriginalName();
                $destinationPath = 'img';
                $filemove = $file->move($destinationPath, $fileimg);
                
                $user->fileimg = $fileimg;
                $user->filemove = $filemove;
                
                $user->save();
                
                $request->session()->flash('Msg', 'Successfully Inserted !!');
                
                return redirect('AdminPanel');
                
            }
        }
        
        else
        {
            
            $user->save();
            
            $request->session()->flash('Msg', 'Successfully Inserted !!');
            
            return redirect('AdminPanel');
        }
  
    }    
    
}

Here is Route.

Route::post('adinsert',[
'uses'=> 'AdminPanelController@adinsert',
'as' => 'adinsert'
]);
