codeigniter没有从控制器获取值来查看

Question

我有以下controllers, models & views结构。

控制器＆gt; （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");
    }
}

模型＆gt; （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＆gt; （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文件中回显$title & $body变量时，我变量是未定义的。任何想法我做错了什么？

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要查看的变量值。

感谢。

在控制器索引（）中尝试添加以下行：

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");
}

}

在show方法或功能中

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

希望它运作良好
