为什么在 laravel 刀片视图上显示未定义的变量

Question

I am passing data from the controller to the blade view, but without session, i cant fetch the data and show my an error.

Answer 1

I think you should return view('route_name', compact('allData')) instead

Note: compact($var_name, ...$var_names)

You could try: back()->with(['allData' => $allData]);
