无法访问视图 codeigniter 中的数据

Question

我有 3 个控制器方法，名称分别为 blog、load_messages 和 load_cmets。现在我想在用户单击按钮时拉出 cmets。 帖子 ID 被传递给方法名称 load_cmets 但现在如果我加载名为 blog 的视图，那么它会给出错误，因为我已经将一些数据传递给了视图。我只想传递作为 cmets 控制器的数据。

功能有：

public function blog() {

    $user_session_email = $this -> session -> userdata('user_email','name','id');
    if(!$user_session_email) {
        redirect('/');
    } 

    $user_data = $this -> users_model -> MyAccount([
        'id' => $this -> session -> userdata('id'),
        'name' => $this -> session -> userdata('name'),
        'email' => $this -> session -> userdata('user_email'),
    ]);
    $data["persoanl"] = $user_data;

    $returned_result = $this -> users_model -> load_messages();
    $messages["message"] = $returned_result['message'];

    $this -> load -> view('users/inc/header', $data);
    $this -> load -> view('users/inc/blog_form', $data);
    $this -> load -> view('users/blog', $messages);
    $this -> load -> view('users/inc/footer');
}

public function load_messages() {
    $returned_result = $this -> users_model -> load_messages();
    $messages["message"] = $returned_result["message"];
    $messages['id'] = $this -> load_comments();
    $this -> load -> view('users/blog', $messages);
}

public function load_comments() {
    $messages['id'] = $this -> input -> post('post_id');
    $this -> load -> view('users/blog', $messages);
}

在最后一个方法中，我只想传递 $message 变量，但是当我将这个值传递给博客视图加载不同参数（如 $messages['message']）的其他函数时，它会生成错误消息$message 在博客视图页面上未定义，但如果我删除最后一个方法，它将完美运行。我应该如何将数据传递到博客？

在load_cmets方法中，需要使用model从数据库中获取数据。
