学习ci,按教程编写,无法加载模型中的方法
<?phpclass News_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_news($slug = FALSE)
{
if ($slug === FALSE)
{
$query = $this->db->get('news');
return $query->result_array();
}
$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
public function set_news()
{
$this->load->helper('url');
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$data = array(
'title' => $this->input->post('title'),
'slug' => $slug,
'text' => $this->input->post('text')
);
return $this->db->insert('news', $data);
}
}
?>

贴上controller <?php
class News extends CI_controller{
public function __contruct()
{
parent::__construct();
$this->load->model('News_model');
$this->load->model('url_helper');
}
public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title']='News archive';
$this->load->view('templates/header',$data);
$this->load->view('news/index',$data);
$this->load->view('templates/footer',$data);
}
public function view($slug=NULL)
{
$data['news_item'] = $this->news_model->get_news($slug);
if(empty($data['news_item']))
{
show_404();
}
$data['title']=$data['news_item']['title'];
$this->load->view('templates/header',$data);
$this->load->view('news/index',$data);
$this->load->view('templates/footer');
}
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();
$this->load->view('news/success');
}
}
}
?> URL http://localhost/index.php/news/index 求帮忙啊!卡了很久了!!!!!!!!试过换版本 没人吗!this->model_name->method()加载不了 应该是Ci的model配置问题!下载后没有改过除index.php,和config.PHP,database.php页面!!!!!求大佬帮助!!!!! 还有是可以加载表单view的,$this->load->model_name从报错上也是可以看出可以加载的 Ricardo 发表于 2018-2-2 12:36

从你的错误信息看明明是没有找到model, 首先你的model是否有放在子目录中 ,放在子目录要加上目录名,其次试试model取个别名再用 我也刚学.勿喷 注意大小写,一个是 news_model 一个是 News_model
