$sheet->loadView('user.list');
});
})->download('xls');
}
Then here is it in my user/list.blade
<div class="row">

<small>#lang('app.list_of_registered_users') - {{ $all }}</small>
</h1>
</div>
</div>
#include('partials.messages')

#endif
</tbody>
</table>
{!! $users->render() !!}
</div>
The problem is that it says an error like "all","companies", and etc are undefined variables. Also because the companies is another table. How can define it in my excel that it won't be error again?

Answer 1

It seems you need to pass variables to view from controller which you are passing. Please check my code and update.
public function userExport()
{
$companies = $this->companyModel->get();
$all = $this->something->get();
Excel::create('data_function',function($excel) use($all, $companies) {
$excel->sheet('mysheet', function($sheet) use($all, $companies) {
$sheet->loadView('user.list', ['all' => $all, 'companies' => $companies]);
});
})->download('xls');
}
and also pass the other variables with same as I passed to $sheet->loadView() in example.
I think this will help you.
