用ci写登录代码，用$this->db->where查询数据库验证账号密码时得到的总是空的返回值
以下是控制器中验证的函数代码：
<code>public function validate_credentials(){
$this->load->model('Bookmark_models');
$query = $this->Bookmark_models->where();
if ($query){
$data = array('username' => $this->input->post('username'),
'is_loggrd_in' => true);
$this->session->set_userdata($data);
$this->load->view('logged_in_area');
}else {
$this->login();
}
</code>以下是模型中的代码：
<code>public function where(){
$this->db->where('username',$this->input->post('username'));
$this->db->where('passwd',sha1($this->input->post('password')));
$query = $this->db->get('user');
if ($query->num_rows == 1){
return true;

if ($query->num_rows == 1){
return true;

用echo $this->db->last_query();输出原生sql语句到数据库中执行看有没有结果.num_rows()是个方法而不是属性
另外也不建议你这么写,模型中就不建议做控制器的事了
<code>public function login($user, $password)
{
return $this->db->where('username', $user)
->where('password', sha1($password))
->get('user')
->row();
}
</code><code>public function where(){
$this->db->where('username',$this->input->post('username'));
$this->db->where('passwd',sha1($this->input->post('password')));
$query = $this->db->get('user');
echo $this->db->last_query();exit();
if ($query->num_rows() ){
return true;
}
return false;</code>
