      validation->username_error; ?>    密码
        
      validation->password_error; ?>    确认密码
        
      validation->passconf_error; ?>    Email
        
      validation->email_error; ?>

controller内容：

$this->load->library('validation');$this->load->helper('form');$rules['username'] = "trim|required|min_length[5]|max_length[16]|xss_clean|callback_username_check";$rules['password'] = "trim|required|matches[passconf]|md5";$rules['passconf'] = "trim|required";$rules['email'] = "trim|required|valid_email|callback_email_check";$this->validation->set_rules($rules);$fields['username'] = '用户名';$fields['password'] = '密码';$fields['passconf'] = '密码确认';$fields['email'] = '邮箱地址';$this->validation->set_fields($fields);if ($this->validation->run() == FALSE){    $this->load->view('user/reg_view');}else{    //调用这个函数保存数据到数据库    $this->user_model->reg();    $this->load->view('user/reg_suc_view');}

model内容：

$activation_key = md5(uniqid() + time());$data = array(    'username' => $this->input->post('username'),    'password' => $this->input->post('password'),    'email' => $this->input->post('email'),    'registered_date' => time(),    'activation_key' => $activation_key,    'status'=>0,    'level'=>0,    'reserve_times'=>0,    'credit'=>0,);$this->db->insert($this->config->item('db_prefix').'user', $data);

碰到类似的表单提交的功能，直接ctrl+c、ctrl+v，改改就能用。
