cakePHP-设置loginRedirect从beforeFilter为admin角色 [英] cakePHP- setting loginRedirect from beforeFilter for admin role

问题描述

我面对这个奇怪的问题。我试图更改admin角色的默认loginRedirect从正常用户的。

U在AppController的组件变量中设置了auth键，如下所示：

 'Auth'=> array（
'loginRedirect'=> array（
'controller'=>'donor'，
'action'=>'index'
）
 ）
  

现在在beforeFilter回调中我有这个设置：

  if（$ this-> Auth-> user（'role'）=='admin'）{
 $ this-& > loginRedirect = array（
'controller'=>'users'，
'action'=>'admin_index'，
'prefix'=>'admin'，
'admin'=> true 
）; 
} 
  

然而，这不工作，if条件永远不会满足。我希望这可以在用户登录时运行。如果我添加 else 条件并重复上面显示的相同的代码，它工作，管理员重定向到所需的页面。

任何人都可以指导我如何正确地做到这一点？提前感谢

解决方案

如果用户未登录， $ this-> Auth-> ; user（）将返回null。 beforeFilter（）将在任何操作运行之前运行，因此您的login（）操作仍未被调用。

在执行 $ this-> Auth-> login（）后重新导向。例如。在您的 UsersController :: login（）操作（或您用于登录的任何操作）：

  if（$ this-> Auth-> login（））{
 if（$ this-> Auth-> user（'role'）=='admin'）{ 
 $ this-> redirect（array（
'controller'=>'users'，
'action'=>'admin_index'，
'prefix'=> ;'admin'，
'admin'=> true 
）; 
} 
} 
  
I am facing this weird problem. I am trying to change the default loginRedirect of the admin role from that of normal user. 

U have the auth key in the AppController's component variable set up as follows : 
'Auth' => array(
            'loginRedirect' => array(  
                'controller' => 'donors',
                'action' => 'index'
            )
    )
Now in the beforeFilter callback I have this set up: 
if($this->Auth->user('role') == 'admin'){
        $this->Auth->loginRedirect = array(
            'controller'=>'users',
            'action'=>'admin_index',
            'prefix'=>'admin',
            'admin'=>true
        );
}
However, this does not work and the if condition is never met. I am expecting this to run when the user logs in. If I add an else condition and repeat the same code shown above, it  works and the admin is redirect to the desired page. 

Can anyone instruct how I am able to do this correctly ? Thanks in advance 
解决方案
If the user is not logged in, $this->Auth->user() will return null. beforeFilter() will run before any action is run, so your login() action has still not been called. 

Do the redirecting after $this->Auth->login() has been called and is successful. E.g. in your UsersController::login() action (or whichever action you use to login):
if ($this->Auth->login()) {
    if($this->Auth->user('role') == 'admin') {
        $this->redirect(array(
            'controller'=>'users',
            'action'=>'admin_index',
            'prefix'=>'admin',
            'admin'=>true
        );
    }
}
