php - Blade Laravel 中的 undefined variable

Question

我的 Controller 里有这个:

public function detail($id) {
    $data = DB::table('data_api')->where('id', $id)->get();
    $carousel = DB::table('data_carousel')->where('data_api_id', $id)->get();
    return view('detail', ['data_api' => $data]);
    return view('detail', ['data_carousel' => $carousel]);
}

但是当我尝试通过 {{ $carousel }} 回显 $carousel 时，它说找不到。但是 $data 工作得很好。有什么想法吗？

Undefined variable: carousel (View: /mylaravelproject/resources/views/detail.blade.php)

Answer 1

您需要将双返回语句更改为单返回

return view('detail', ['data_api' => $data]);
return view('detail', ['data_carousel' => $carousel]);

到

return view('detail', ['data_api' => $data, 'data_carousel' => $carousel]);
