Question

i have address Book table and user table i am assigning
the many user in my address book while i am created everything is fine(ok)
but when i am editing every data back in my form without assign user .
how can i get the user in editing form ?? this is my Address Book Controller
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests\AddressRequest;
use App\Http\Requests;
use App\Models\Address;
use App\Models\User;
use App\Http\Controllers\Controller;`enter code here`
use Illuminate\Pagination\Paginator;
use Auth;
use DB;
use Session;
class AddressesController extends Controller
{
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index(Request $request)
{
Session::forget('searchaddress');
$addresses = Address::orderby('company_name');
$company_name = $request->input('company_name');
if(!empty($company_name)) {
//$addresses->where('company_name','LIKE','%'.$company_name.'%');
$addresses->where('company_name','LIKE','%'.$company_name.'%');
Session::set('searchaddress', $company_name);
}
$addresses = $addresses->paginate(5);
return view('address.index',compact('addresses'));
}
/**
* Show the form for creating a new resource.
*
* #return Response
*/
public function create()
{
$users = User::lists('first_name','id');
return view('address.create',compact('users'));
}
/**
* Store a newly created resource in storage.
*
* #return Response
*/
public function store(AddressRequest $request)
{
$address = Address::create($request->all());
$firstname = Auth::user()->first_name;
$lastname = Auth::user()->last_name;
$address->created_by =$firstname." ".$lastname;
$address->users()->attach($request->input('user_list'));
$address->save();
return redirect('/addresses');
}
/**
* Display the specified resource.
*
* #param int $id
* #return Response
*/
public function show($id)
{
$address = Address::find($id);
return view('address.show',compact('address'));
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return Response
*/
public function edit($id)
{ $users = User::lists('first_name','id');
$address = Address::findorFail($id);
return view('address.edit',compact('address','users'));
}
/**
* Update the specified resource in storage.
*
* #param int $id
* #return Response
*/
public function update( AddressRequest $request ,$id)
{
$address = Address::findOrFail($id);
$address->update($request->all());
$address->users()->sync($request->input('user_list'));
return redirect('/addresses');
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return Response
*/
public function destroy($id)
{
$address = Address::find($id);
$address->delete();
return redirect('/addresses');
}
}
and that is my AddressBook Model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Address extends Model
{
protected $fillable = [
'created_by',
'company_name',
'phone',
'email', 'address','comment'
];
public function users()
{
return $this->belongsToMany('App\Models\User')->withTimestamps();
}
public function getUserListAttribute()
{
return $this->users->lists('id');
}
}

Answer 1

You have belongsToMany relation, so in your edit action you also should get current Address users like this
public function edit($id)
{ $users = User::lists('first_name','id');
$address = Address::findorFail($id);
$address_users = $address->users->lists('id')->toArray();
return view('address.edit',compact('address','users', 'address_users'));
}
then in your view in select you should intersect arrays of $users and $address_users to get selected options.
{!! Form::select('user_list[], $users, isset($address_users) ? $address_users : null, ['id' => 'users_list', 'class' => 'form-control', 'multiple']) !!}
to avoid
isset($address_users) ? $address_users : null
you can define empty address_users array in your create method and do it like this
$address_users
