我发现 dx_auth在Codeigniter中相当不错,并且之前使用过它.它肯定是Codeigniter最全功能的身份验证库.

我需要做一些事情来改变它,所以我为他的目的扩展了他们的User类,有一些函数(他们的一些函数并没有完全符合你的预期……).以下是我所做的一些自定义的一部分：

$CI = &get_instance();
     $CI->load->;model("dx_auth/users");
     /**
     * For most things,try and use the dx_auth models,* because it's already done,and some stuff is more 
     * annoying to figure out than might be expected.
     *
     * For anything site-specific,use this model instead.
     *
     */

     class UserModel extends Users {
        /**
        * Sometimes when dx_auth sucks,you have to compensate 
        * functions that return useful results.
        *
        * @param int $id id of user to check if banned
        * @return int $banned returns the result (0 or 1)
        */
       public function is_banned($id) {
            $query = "SELECT banned From users WHERE id=".(int)$id;
            $result=$this->db->query($query);
            $row = $result->row_array();
            return $row['banned'];
       }


    }
