Question

我正在尝试创建一个小应用程序，因此我选择了无脂肪框架。我需要根据成功或错误显示一些消息。假设我是否要添加用户，那么如果成功添加了显示消息，表明用户已成功添加，或者如果没有显示错误消息，则表示无法添加用户。我想不明白。这是我的Userscontroller代码

 public function index(){
     $user = new User($this->db);
     $this->f3->set('users',$user->all());
     //there should be a way to decide if its error message or success and after display, 
     //it shouldn't be displayed again for the same task.
     //or may be it should be check in view file, I don't know where is the correct place
     // to do it
     $this->f3->set('page_head','User List');
     $this->f3->set('view','users/list.htm');

}

  public function create(){
    if($this->f3->exists('POST.create')){
    $user = new User($this->db);
    $user->add();
    //set session here to show in view file after redirect to list page
    $this->f3->reroute('/users');
   } else{
    $this->f3->set('page_head','Create User');
    $this->f3->set('view','users/create.htm');
   }
 }

我的Flash消息控制器如下所示：https://github.com/ikkez/f3-flash/blob/master/lib/flash.php

设置消息：

if ($this->resource->updateProperty(array('_id = ?', $params['id']), 'published', true)) {
  \Flash::instance()->addMessage('Your post was published. Hurray!', 'success');
} else {
  \Flash::instance()->addMessage('This Post ID was not found', 'danger');
}
$f3->reroute('/admin/post');

为了呈现消息，我在我的布局https://github.com/ikkez/fabulog/blob/master/app/ui/templates/alert.html中包含了这个模板，该模板调用了一个转储和清除所有消息的函数，因此它们只会显示一次。您还可以在{{@SESSION.flash}}等模板令牌中使用SESSION，并将其用于模板中的<repeat>。

如何在无脂肪框架中使用Flash消息？
