            <!-- /.panel-heading -->
            <div class="panel-body">
        @if(isset($success_alert))
            <div class="alert alert-success">{{$success_alert}}</div>
        @endif
        @if(isset($danger_alert))
            <div class="alert alert-danger">{{$danger_alert}}</div>
        @endif


            @foreach($data as $dat)


                <div class="col-lg-3">
                    <button class="btn btn-default">{{$dat->name}}</button>
                    <hr>
                </div>

Answer 1

The issue would be with this piece of code, $role2s is an object. Since you are trying to print the object it is throwing the error

<button class="btn btn-primary">{{$role2s}}</button>

Trying running var_dump on the particular variable.

Answer 2

Try to do this: it works 100%

$rolepermissiongetid =DB::table('permission_role')->select('role_id')
 ->where('permission_role.role_id' , $id)
    ->get();




$arrQuery = array();
foreach($rolepermissiongetid as $key => $rolepermissiongetid){
$arrQuery[$key] = rolepermissiongetid->role_id;
 }




$notrolepermision =DB::table('permission_role')
    ->join('permissions', 'permissions.id', '=', 'permission_role.permission_id')
    ->whereNotIn('permission_role.role_id' ,$arrQuery)
    ->get();

Answer 3

curly braces are equals to PHP's echo statement. In $role2s variable you are getting object/array so it'll not print but give you an error. So you can use below solution. and after that -> or [' '] get it's object or array.

Try

{{dd($role2s)}}

or

{{print_r({{$role2s}})}}

or

{{var_dump({{$role2s}})}}

Answer 4

You don't have specify your exact error. But May be error is in controller. check code below

$notrolepermision =DB::table('permission_role')
        ->join('permissions', 'permissions.id', '=', 'permission_role.permission_id')
        ->whereNotIn('permission_role.role_id' ,$rolepermissiongetid->role_id) //<--------------check this line you need $rolepermissiongetid->role_id in stead of $rolepermissiongetid
        ->get();
