codeigniter没有从控制器获取值到视图

I have following controllers, models & views structure.

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>

Now I have created another function in my controller file content.php:

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

Now when I am trying to echo $title & $body variable inside content_page file I am getting variable is undefined. Any Idea what I am doing wrong?

Error List:

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

So I want to know how to display variable values to view.

Thanks.

In controller index () try adding this line:

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);
    $this->show($data);
    $this->load->view("global_footer");
}

}

In show method or function

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

Hope it works fine
