错误：未定义属性：News :: $ code_iterate中的form_validation [英] error: Undefined property: News::$form_validation in codeigniter

问题描述

我是新的codeigniter，并尝试在用户指南中的教程。但我坚持我的第三个教程是为创建新闻项目。这里在我的控制器部分它给出以下错误：

I am new to the codeigniter and trying the tutorials in the user guide. But i stuck i the third tutorial which is for the create news items. Here in my controller section it is giving the following error:

严重性：注意

消息：未定义属性：新闻:: $ form_validation

Message: Undefined property: News::$form_validation

档案名称：controllers / news.php

Filename: controllers/news.php

行号：44

并且我在控制器部分使用的代码是

and the code that i used in the controller section is

public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');

$data['title'] = 'Create a news item';

$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('text', 'text', 'required');

if ($this->form_validation->run() === FALSE)
{
    $this->load->view('templates/header', $data);   
    $this->load->view('news/create');
    $this->load->view('templates/footer');

}
else
{
    $this->news_model->set_news();
    $this->load->view('news/success');
}
}

请帮助我。

提前感谢。

推荐答案

推荐你不指定加载模型。

Propably you don't specify loading model. So include this before

$this->load->model('news_model');

之后您可以呼叫

$this->news_model->set_news();

或编辑config\autoload.php并设置模型，然后可以成功验证后使用

or edit config\autoload.php and set your model, then you can use after successfully validation

news_model::set_news();

或者你可以在构造函数中这样：

or you can that in constructor, like this:

class MySomeClas extend CI_Controller
 {
  parent::__construct();
  $this->load->model('news_model');
 }

和拨打型号
