为什么 $this->load->library('form_validation', 'verify'); 这个会加载失败？还有如果将 $this->load->model('category_model', 'cate'); 放在 add() 函数里也会出现下面的提示：
A PHP Error was encounteredSeverity: Notice
Message:  Undefined property: Article:: $cate
Filename: admin/article.php
Line Number: 19


Fatal error:  Call to a member function fetch() on a non-object in E:\htdocs\icms\app\controllers\admin\article.php on line 19

为什么$this->load->model('category_model', 'cate'); 这个也会加载失败？

Closer

1. 確認你的 config\form_validation.php 內有 article 驗證規則
2. 應避免使用關鍵字來做簡寫 $this->post->add($data);
3. 若在 add() 放入 $this->load->model('category_model', 'cate');
　 則必須放在 $data['category'] = $this->cate->fetch(); 之前
4. $this->load->model('category_model', 'cate'); 加載失敗
　 請檢查路徑與 model 名稱正確
　 (包括檔名與 class Category_model extends CI_Model {} )
