php - 使用 php 传递变量生成 PDF

Question

Web.php 我尝试创建一个空白路由来传递 $contract 变量，以传递变量以使用 dompdf 生成 pdf

Route::get('/blank', function () {
    return view('sell.contractpdf','PdfGenerateController@contract')->name('viewpdf');
});

contractpdf Controller

public function pdfview(Request $request)
{
    $contract = Contract::findOrFail(session('contract_id'));
    $pdf = App::make('dompdf.wrapper');
    $pdf = PDF::loadView('sell.contractpdf', $contract);
    return $pdf->stream();
}

在 View 中:

<h1>f</h1>
@foreach ($contracts as $contract)
<h4>{{$contract->id}}</h4>
@endforeach

错误: undefined variable :合约

Answer 1

这应该是

$contracts

$contracts = Contract::findOrFail(session('contract_id'));
$pdf = PDF::loadView('sell.contractpdf', ['contracts' => $contracts]);
