我在创建权限菜单时遇到问题,
我有一个桌面用户..
用户名,密码,权限。
我在这样的模型中有一个函数..
function valid_login($username, $password)
{
$query = $this
->db
->where('username', $username)
->where('password', md5($password))
->limit(1)
->get('user'); /
if ($query->num_rows() == 1) {
return $query->row_array();
}
else
{
return FALSE;
}
}
来自控制器的值发布,像这样的脚本..
public function index()
{
if ( isset($_SESSION['permission']) ) {
redirect('home_controller/home');
}
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required|min_length[4]');
if ( $this->form_validation->run() == TRUE ) {
$this->load->model('m_user');
$result = $this->m_user->valid_login(
$this->input->post('username'),
$this->input->post('password')
);
if ($result == TRUE) {
$_SESSION['permission'] = ????;
redirect('home_controller/home');
}
}
$this->load->view('login_form');
}
我不明白,如何从模型中获取字段权限值。我需要该值来创建$ _SESSION ..
myView就像这样......
<?php
if($_SESSION['permission']=="Administrator"){
$this->load->view('administrator_menu');;
}else{
$this->load->view('user_menu');;
}
?>
感谢您的关注.. 任何人都可以帮助我..

像这样设置CI
中的会话:
if ($result == TRUE) {
print_r( $result );die;
//$this->sesson->set_userdata('logged_user', $result); #this to set the session with the returned result
$_SESSION['permission'] = $result['permission']; #set permission from the result in the session
redirect('home_controller/home');
}
现在读取会话是否存在或不这样做:
if( $this->session->userdata('logged_user') ){
echo "The user id stored in session is :".$id = $this->session->userdata['logged_user']['id'];
}else{
redirect('someplace', 'refresh');
}
编辑:
要开始会话,首先在application / autoload.php中自动加载它:
$autoload['libraries'] = array('session');
其次在encryption key
中设置一个随机application/config.php
,如下所示:
$config['encryption_key'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
