从Laravel导出到Excel表

Question

我很困惑为什么我不能将其导出到Excel。 请帮我。 无法读取“全部”的错误。 这是我的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');
}

然后在我的用户/ 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>

@include('partials.messages')
    <form method="GET" action="" accept-charset="UTF-8" id="users-form">
<div class="row tab-search">
        <div class="col-md-2">
            <div class="form-group-sm">

                    @foreach ($companies as $company)
                        @if (($company->id)=="1")
                        <option>All</option>
                        @else
                        <option value="{{ $company->id }}">{{ $company->name }}</option>
                        @endif
                    @endforeach

问题是它说像“所有”，“公司”等错误是未定义的变量。 也因为公司是另一张桌子。 如何在Excel中将其定义为不会再次出错？

Answer 1

似乎您需要传递变量以从正在传递的控制器中进行查看。 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，与示例中传递给$sheet->loadView()变量相同。 我认为这会对您有所帮助。
