未定义的变量php laravel 5.4

Question

i kept getting the same error, 我一直遇到同样的错误，

undefined variable: theaters on my blade, line 14. 未定义的变量：我的刀片上的影院，第14行。

here is my addcine.blade.php line 14 这是我的addcine.blade.php第14行

@foreach ($theaters as $theater)
    <option value="{{ $theater->name }}"/>
    @endforeach

here is my addcinemacontroller 这是我的addcinemacontroller

public function index(){

$theaters = Theater::all();

return view('schedules.addcine', compact('name'));

and my route 和我的路线

Route::get('addcinema','AddCinemaController@index');
});

Answer 1

It should be: 它应该是：

return view('schedules.addcine', compact('theaters'));

compact('theaters') does exactly this: compact('theaters')正是这样做的：

return view('schedules.addcine', ['theaters' => $theaters]);

Answer 2

return view('schedules.addcine', compact('theaters'));

您没有将$theaters值发送给视图，

Answer 3

You are sending name instead of theaters in controller 您正在发送name而不是控制器中的theaters

public function index(){

$theaters = Theater::all();

return view('schedules.addcine', compact('theaters'));

Answer 4

You need to return the $thaters variable to view so that you can use it there. 您需要返回$thaters变量进行查看，以便可以在其中使用它。

Return like this: 这样返回：

return view('schedules.addcine', compact('theaters'));
