从laravel出口到excel一张桌子

Question

我很困惑，为什么我无法将其导出为ex​​cel。请帮我。这是一个错误，它无法读取“全部”。 这是我在UsersController中的代码

public function userExport()
{
    Excel::create('data_function',function($excel){
        $excel->sheet('mysheet', function($sheet){
            $sheet->loadView('user.list');
        });
    })->download('xls');
}

然后在我的user / list.blade

中

<div class="row">
    <div class="col-lg-12">
        <h1 class="page-header">
            Employees
                <small>@lang('app.list_of_registered_users') - {{ $all }}</small> 
        </h1>
    </div>
</div>

                    @foreach ($companies as $company)

问题在于它说“全部”，“公司”等错误是未定义的变量。也因为这些公司是另一张桌子。如何在我的Excel中定义它不会再出错？

Answer 1

您似乎需要将变量传递给要传递的控制器进行查看。请检查我的代码并更新。

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');
}

并传递其他变量，与我在示例中传递给$sheet->loadView()的变量相同。 我想这会对你有帮助。
