Php 尝试获取Codeigniter模板中非对象的属性

我使用codeigniter制作简单的模板。 我的代码是这样的

这是template.php类

这是我的controller welcome.php类

这是我的视图类，welcome_message.php类

但我得到的错误如下：

A PHP Error was encountered

Severity: Notice

Message: Trying to get property of non-object

Filename: libraries/template.php

Line Number: 25

对不起，我还是codeigniter和php的新手。请帮帮我。

首先，你的构造方法不对，它应该是

\uu-construct

而不是

\u-construct

---

其次，使用

$this->\u ci->load->view（'/template.php'，$data）加载视图时，不应在开始路径上使用任何斜杠，直到CI可以使用视图目录。因此，如果您的视图文件是CI视图文件夹中的
template.php，则以这种方式使用它
$this->\u CI->load->view（'template'，$data）。您还可以使用
.php
扩展CI self添加该扩展。
我认为您的构造函数只有一个
。
。它应该是两个下划线：
\u构造函数（）
if (!defined('BASEPATH'))
exit('No direct script access allowed');

class Welcome extends CI_Controller {

function __construct() {
    parent::__construct(); //you always have to call parent's constructor before ANYTHING
    $this->load->library('template');
    $this->load->helper('url');
}

public function index() {
    $this->template->display('welcome_message');
}

function contoh_parameter() {
    $this->template->display('view_parameter', array('judul' => 'Judul View'));
}

}

   <h1>Welcome to CodeIgniter!</h1>

   <div id="body">
