我试图将多个参数传递给同一个视图，laravel向我抛出一个错误，说未定义变量$blogs。我已经将变量$all_cards传递到相同的视图，但从另一个控制器从HomeController.php到index()。问题是Laravel正在读取$all_cards，但没有第二个变量$blogs。Compact ()，with()，view()这些函数都不起作用。而Laravel总是抛出同样的错误。
BlogController.php
class BlogController extends Controller
{
public function index()
{
$blogs = Blog::all();
return view('home.home',['blogs'=>$blogs]);
}
}

=>if you display all record using foreach in view and blogs variable compact in your compact. ['blogs'=>$blogs] you can not using this variable on your controller that is not support if you pass multiple variable so compact.
->return your page and blogs that is your list of data. that is working try.
return view('home.home',compact('blogs'));
