Laravel 项目未定义变量 $stores

Question

我是 Laravel 的初学者，我正在创建一个带有 CRUD 操作的简单 Laravel 项目。现在我有两个数据库表：store 和employee。我已经完成了其他功能，例如创建一个带有姓名、位置等字段的新商店，如员工中那样。

现在，我想在两者之间建立关系，并且我尝试在创建新员工中放置一个下拉列表，其中显示商店数据库表中的商店名称。

有人可以检查我的代码吗？我哪里做错了？

Answer 1

不知道为什么在你的控制器中有

createEmployee

和

cccreateEmployee

方法，但看看代码：

public function ccreateEmployee()
{
    return view('employees.createEmployee');
}

您没有将

$stores

变量传递给视图
