我是 codeigniter 的新手。我已经实现了一个简单的登录系统。我想在我的视图页面上打印一个用户名，该用户名存储在会话中。这是我的控制器

$this->load->view('loginTemplate/template', $new);
}
function verifyUser(){
//getting parameters from view
$data = array(
'username' => $this->input->post('username'),
'password' => $this->input->post('password')
);
$this->load->model('loginModel');
$query = $this->loginModel->validate($data);
if ($query){
//if the user c validated
//data variable is created becx we want to put username in session
$data = array(
'username' => $this->input->post('username'),
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('sessionController/dashboard_area');

$username = $this->session->userdata('username');
//Pass it in an array to your view like
$data['username']=$username;
$this->load->view('test',$data);
//Then in you view you can display it as:
echo $username;

controller file $data = array( 'username' => $result->name, );
控制器文件 $data = array( 'username' => $result->name, );
view file
查看文件
<?php echo $this->session->userdata('username')?>
回答by Jo?o Dias
Just store the user name in the userdata (you've already done this!)
只需将用户名存储在 userdata 中（您已经这样做了！）
$this->session->set_userdata('username') = 'John Doe';
And retrieve it just like that
并像那样取回它
$username = $this->session->userdata('username');
