无法通过 Compact 方法将变量从 LoginController 发送到 Blade 文件以显示变量值 - 显示我（未定义的变量）

Question

我在尝试从登录控制器中创建的方法传递变量以将其传递到刀片文件时遇到问题 - 当按登录按钮查看登录用户的 id 时，尝试以用户身份为他打开受限区域，而其他人则不能查看其他用户的页面或区域

尝试通过紧凑的 hellper 方法将登录方法中的变量 $userDataa 从 LoginController 发送到 balde 文件 Home.blade.php，但在登录时显示未定义的变量 $userDataa 尝试在 Blade 文件 {{$userDataa} 中回显它}

Answer 1

您尝试过使用

Auth

门面或

auth

助手吗？像这样

Auth::user()->name

或

auth()->user()->name

。在验证用户身份后，您不必将其手动传递到刀片文件。
