Call to undefined method stdClass::isEmpty() error

I am trying to check if the $pl1 is empty but it does not seems to work. I tried using count() but does not seems to work either.

controller:

$paperlist1 =   DB::table('upload_papers')
                        ->join('courselist','courselist.id', '=', 'upload_papers.courselist_id')
                        ->join('users','users.id','=','upload_papers.upload_by')
                        ->select('upload_papers.file_name','upload_papers.paper_no','upload_papers.path','users.role_id')
                        ->where([
                            ['courselist.faculty_id','=',$facultyid],
                            ['upload_papers.courselist_id','=',$id],
                            ['upload_papers.paper_no','=',1]
                            ])
                        ->get();

blade.php:

<tr>
@foreach($paperlist1 as $pl1)
                    @if(!$pl1 -> isEmpty())
                        @if($pl1->role_id === 2)
                        <td><a href="/{{ $pl1->path }}">{{ $pl1->file_name }}</a></td>
                        @else
                        <td>-</td>
                        @endif
                        @if($pl1->role_id === 3)
                        <td><a href="/{{ $pl1->path }}">{{ $pl1->file_name }}</a></td>
                        @else
                        <td>-</td>
                        @endif
                      </tr>
                        @break
                    @endif
                  @endforeach

CodePudding user response:

The variable $paperlist1 is the Collection, so ->isEmpty() will only work on $paperlist1 and not on $pl1 as $pl1 is each value of the collection.

So, @if(!$pl1 -> isEmpty()) (that could be more readable if you used @if($pl1->isNotEmpty())) will not make sense at all, because you already have data.
