推荐答案
使用codeigniter 3时
When using codeigniter 3
所有控制器和模型都应有类名和文件名的第一个字母作为大写示例 Welcome.php ，而不是welcome.php
All controllers and models should have there first letter of class name and file name as upper case example Welcome.php and not welcome.php
对于您的模型，因为它与控制器具有相同的名称。我会将模型名称更改为Model_post
For your model because it is the same name as controller. I would change model name to Model_post
文件名：Model_post.php
<?php
class Model_post extends CI_Model {
public function some_function() {
}
}
这样codeigniter不会感到困惑。
That way codeigniter will not get confused.
Post控制器是
文件名：Post.php
<?php
class Post extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('model_post');
}
public function index() {
$this->model_post->some_function();
}
}
up codeigniter / htaccess删除index.php然后你的url将需要使用index.php每个地方。
Also in your url if not set up codeigniter / htaccess to remove index.php then your url will need to use index.php every where.
http://localhost/project/index.php/post
http://www.example.com/index.php/post
之前版本的codeigniter before v3你不需要担心ucfirst为控制器，但现在你做的版本3及以上。
Previous versions of codeigniter before v3 you did not need to worry about ucfirst for controllers but now you do for version 3 and above.
