laravel - 将变量从 DOMPDF Controller 传递到 View

Question

我想用 laravel 创建一个 DOMPDF，我必须传递我的变量来查看。我一直在尝试传递如下变量，但它仍然无法正常工作。

这是我的 Laravel Controller

 public function pdf(Request $request, $id){
    $salesorder = $this->show($id)->salesorder;
    $detailservice = $this->show($id)->detailservice;
    $detailemployee = $this->show($id)->detailemployee;

    $data = [$salesorder, $detailemployee, $detailservice];

    $pdf = PDF::loadView('summary.invoice', $data);
    return $pdf->download('invoice.pdf');
}

我认为的错误是:

Undefined variable: salesorder

如何将一些变量从 Laravel Controller 传递给 DOMPDF ？

PS:dd($data)结果是正确的

Answer 1

您必须通过 data如下

$data = [
    'salesorder'     => $salesorder,
    'detailemployee' => $detailemployee,
    'detailservice'  => $detailservice
];

或尝试使用 compact

$data = compact('salesorder', 'detailemployee', 'detailservice');
