Wie setze ich eine Checkbox in Laravel?

Question

In meiner Laravel Arbeit Admin zuweisen Rollen zu Benutzern.Assigning erfolgt über Checkbox.Aber wenn bereits zugewiesenen Benutzer, Kontrollkästchen sind nicht angekreuzt. Markieren Sie die Kontrollkästchen, die bereits zugewiesen sind.

// Controller

<?php 

namespace App\Http\Controllers\admin; 

use Illuminate\Http\Request; 
use Session; 
use Redirect; 
use Response; 
use App\Http\Controllers\AdminController;

use App\Http\Requests\ShopUpdateRequest; 
use DB; 
use App\Customer; 
use App\MyRoles; 
use App\Roles; 
use Assets; 
use Auth; 
use Datatables; 

class EmployeeController extends AdminController 
{ 

    public function assignrole(){ 
     $title = "Prizes"; 
     $post = 0; 
     $count = 0; 
     $employees = User::where('employee','yes')->get(); 
     $roles = Roles::select('roles.role_name','roles.id')->get(); 

     return view('app.admin.roles.assignrole', compact('title','post','count','roles','employees')); 
    } 


    public function postassignrole(Request $request){ 
     $title = "Prizes"; 
     $post = 0; 
     $count = 0; 
     $employee = User::where('id',$request->employee)->pluck('username');//current employee name 
     $emp_id = $request->employee;//current employee id 
     $roles = Roles::select('roles.role_name','roles.id')->get();//all links 
     return view('app.admin.roles.postassignrole',compact('title','post','count','roles','employee','emp_id')); 
    } 

    public function saverole(Request $request){ 
     $array = $request->all();//employee id 
     $emp_id = $array['emp_id'];//after assigning roles gives employee id 
     $i = 0; 
     MyRoles::where('user_id',$emp_id)->delete(); 
     foreach($array as $data){ 

      if($i == 0){ 

      }else{ 
       MyRoles::create(
        [ 
         'user_id' => $emp_id, 
         'role_id' => $data 
        ] 
        ); 
      } 
      $i++; 

     } 
     Session::flash('flash_notification', array('level' => 'success', 'message' => 'customer created successfully')); 
     return Redirect::action('Admin\EmployeeController@assignrole'); 
    } 
}

Verwenden Abfrage der bereits zugeordneten Rollen für einen Mitarbeiter in dem vorhergehenden Bildschirm ausgewählt zu holen. Übergeben Sie es dann zur Ansicht. Und wenn Rollen zugewiesen werden, markieren Sie die Rollen-ID als markiert.
