CakePHP检查用户是否在视图中登录 [英] CakePHP check if user is logged in inside a view

问题描述

我有以下代码：

 <？php 
 
 if - > Auth-> user（））
 {
 echo $ this-> element（'header'）; 
} 
 else 
 {
 echo $ this-> element（'header-bar'）; 
} 
 
？> 
  

在我的视图内，应该显示一个不同的标题为登录用户，但抛出以下错误：注意（8）：未定义属性：View :: $ Auth [APP / views / layouts / page.ctp，第17行] $（


$ b <$ c
致命错误：调用成员函数user（）on /Users/cameron/Sites/thehive/app/views/layouts/page.ctp on line 17上的非对象

如何解决这个问题？感谢

Auth组件用于控制器。你需要在控制器中检查授权，然后为视图设置一个变量，例如 $ this-> set（'authUser'，$ this-> Auth-> user ））; 。然后在您的视图中，您可以：

  if（！$ authUser）
 {
 echo $ this - > element（'header'）; 
} 
  

如果您希望所有控制器方法都自动完成，修改 cake / libs / controller / app_controller.php ，使其包含Auth组件。

I have the following code:

    <?php

    if (!$this->Auth->user())
    {
        echo $this->element('header');
    }
    else
    {
        echo $this->element('header-bar');
    }

    ?>

inside my view which should show a different header for logged in users but throws the following error:

Notice (8): Undefined property: View::$Auth [APP/views/layouts/page.ctp, line 17]
Fatal error: Call to a member function user() on a non-object in /Users/cameron/Sites/thehive/app/views/layouts/page.ctp on line 17

How do I fix this? Thanks

The Auth component is for use in the Controller. You'll want to check for authorization in the controller, then set a variable for the view, e.g., $this->set('authUser', $this->Auth->user());. Then in your view you can do:

if (!$authUser)
{
    echo $this->element('header');
}

If you want this to be done automatically for all controller methods, you can look into modifying cake/libs/controller/app_controller.php so that it includes the Auth component.
