仅在主页上显示块 HTML？

我尝试修改家庭控制器添加新变量：

$data["header_home"] = true;

然后我尝试检查一下header.twig模板如下：

{% if header_home %}
    <div>Home</div>
    {% else %}
<div>Not Home</div>
{% endif %}

当我通过 index.php 或仅 url 地址打开主页时，它不起作用，我的意思是我没有看到<div>Home</div>.

怎么解决，哪里出错了？

这是家庭控制器：

<?php
class ControllerCommonHome extends Controller {
    public function index() {
        $this->document->setTitle($this->config->get('config_meta_title'));
        $this->document->setDescription($this->config->get('config_meta_description'));
        $this->document->setKeywords($this->config->get('config_meta_keyword'));

        if (isset($this->request->get['route'])) {
            $this->document->addLink($this->config->get('config_url'), 'canonical');
        }

        $data["header_home"] = true;
        $data['column_left'] = $this->load->controller('common/column_left');
        $data['column_right'] = $this->load->controller('common/column_right');
        $data['content_top'] = $this->load->controller('common/content_top');
        $data['content_bottom'] = $this->load->controller('common/content_bottom');
        $data['footer'] = $this->load->controller('common/footer');
        $data['header'] = $this->load->controller('common/header');

        $this->response->setOutput($this->load->view('common/home', $data));
    }
}
