CakePHP如何创建函数并从视图中调用它们

Question

How can I create functions that can be called in view (like in the index.ctp)?

I just wrote a function in one of my controllers:

public function getName($id) {
    $name = $users
      ->find()
      ->where(['id' => $id ])
      ->first()
      ->username;
    return $name;
}

The function should return the username according to the $id passed as a parameter. I just want to know how can I call a function from within my views. I'm getting this error:

"Error: Call to undefined function getName()"

You can do it, but it is against MVC-model and is not in anyway recommended.

Namespace\ControllerName::getName(1)

You should really consider taking look CakePHP manual and understand, how to set variables to view from controller http://book.cakephp.org/3.0/en/views.html#setting-view-variables

Other option would be making AJAX-request to your controller, if you want get data based on for e.g. user actions in view.
