。 htaccess在应用程序文件夹中

<IfModule authz_core_module>
Require all denied
</IfModule>
<IfModule !authz_core_module>
Deny from all
</IfModule>

autoload.php

autoload.php

$autoload['libraries'] = array('database');
$autoload['helper'] = array('url');

        $this->db->select()->from('posts')->where('active', 1)->order_by('date_added', 'desc')->limit(0, 20);

        $data['posts'] = $this->post->get_posts();
        echo "<pre>";
            print_r($data['posts']);
        echo "</pre>";      

    }

}

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

注意：如果您需要
htaccess在主目录中添加一个，请不要触摸应用程序文件夹中的htaccess
用于Codeigniter的Htaccess

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.
