Kohana：尝试动态更改内容（而不是整个页面）

I am struggling to get my head around this since too many hours and I need some help.:) I have a website build on Kohana and want to dynamically change the content of some text when the user click one button or and another. Not sure if I am doing it the right way but this what I did so far (ho by the way I am new to this framework).

我正在努力解决这个问题，因为太多时间我需要一些帮助。:)我有一个建立在Kohana上的网站，并希望在用户点击一个按钮或另一个时动态更改某些文本的内容。不确定我是否采用正确的方式，但这是我迄今为止所做的事情（顺便说一下，我是这个框架的新手）。

Controller:

控制器：

class Controller_Homepage extends Controller_General {

   public $template = "template/widepage";

   public $textbuyer = array (
        'text1' => "homepage.buyer.bigtext1", //transfering language variable.
        'text2' => "homepage.buyer.bigtext2",
        //with more ...
       );   

   public $textseller = array (
        'text1' => "homepage.seller.bigtext1",
        'text2' => "homepage.seller.bigtext2",
        'text3' => "homepage.seller.bigtext3",
        //with more ...
       );   
    public $thetext = array ("textbuyer"); //the defaul array is textbuyer

public function action_index() {

public function action_index（）{

        $this->content = View::factory("homepage") 
            ->bind('pagetext', $thetext );


        if ($this->request->method() === Request::POST) {
            $post= $this->request->post();
            if (isset($post['buyer'])){
                $thetext = $textbuyer;//gives rrorException [ Notice ]: Undefined variable: textbuyer
            //    arr::overwrite($thetext, $textbuyer);
            }else if(isset($post['seller'])){
                $thetext = $textseller;
                }
        }

}

Section of my view to show how I use the variable in the view:

我的视图部分显示了我如何在视图中使用变量：

        <div class="container_content">
            <div>
                <p id='sline'><?php echo $pagetext['text1']; ?></p>
            </div>
            <div>

Can't get the content of my array to the view and when I click on one of the two buttons this code gives me the following error: ErrorException [ Notice ]: Undefined variable: textbuyer. What I am doing wrong ? Why I get the error I mentionned ? Thank you!

无法将我的数组的内容添加到视图中，当我单击其中一个按钮时，此代码会给出以下错误：ErrorException [Notice]：未定义的变量：textbuyer。我做错了什么？为什么我收到我提到的错误？谢谢！

When you define the variables like this

当您定义这样的变量时

public $textbuyer = ...
public $textseller = ...
public $thetext = ...

They are attributes of your class. And since they are, you need to call them via

它们是您班级的属性。既然它们是，你需要通过它们来调用它们

$this->textbuyer
$this->textseller
$this->thetext

Just as you call methods inside the same class with $this->methodName() instead of methodName().

正如您使用$ this-> methodName（）而不是methodName（）调用同一类中的方法一样。

class Foo {
    public $bar = "hello ";
    public function foo() {
        $bar = "world";
        print $this->bar.$bar; // hello world
    }
}

This would work just fine and you get the error because you never define $textbuyer (because you want to call $this->textbuyer).

这可以正常工作，你得到错误，因为你从来没有定义$ textbuyer（因为你想调用$ this-> textbuyer）。
