编码器不能从控制器到视图获取值

我有以下controllers, models & views结构:

controllers> (content.php)

class Content extends CI_Controller {
    public function __construct(){
        parent::__construct();
    }
    public function index() {
        $this->load->view("global_header");
        $this->load->model("ContentModel");
        $data['result'] = $this->ContentModel->blogPostContents();
        $this->load->view("content_page", $data);
        $this->load->view("global_footer");
    }
}

models> (ContentModel.php)

class ContentModel extends CI_Model {
    public function blogPostContents() {
        $url_segment = $this->uri->segment(1); // Get post title
        $this->db->select('*');
        $this->db->from('blog_posts');
        $this->db->where("url", $url_segment);
        $query = $this->db->get();
        $query->result();
        $this->db->last_query();
        return $query->result();
    }
}

views> (content_page.php)

<article>
    <div class="container">
        <div class="row">
            <div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
                <?php
                    echo $result[0]->post;
                ?>
            </div>
        </div>
    </div>
</article>

现在我在控制器文件content.php中创建了另一个函数:

public function show() {            
    $data['title'] = "Hello";
    $data['body'] = "World";
    $this->load->view('content_page', $data);
}

现在，当我试图在content_page文件中回声$title & $body变量时，我得到的变量是未定义的。知道我做错了什么吗?

错误列表:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: title
Filename: views/content_page.php
Line Number: 5
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: body
Filename: views/content_page.php
Line Number: 6

所以我想知道如何显示变量值。

谢谢。
