Login is not working

Hello,
I have a login installed.
The bulk works.
But when I go to account.php, nothing is displayed there.
I hope you can continue helping me there.

Controller:

PHP Code:

<?php

View

Code:

<!DOCTYPE html>
<html lang="en">  
<head>
<link href="<?php echo base_url(); ?>assets/css/style.css" rel='stylesheet' type='text/css' />
</head>
<body>
<div class="container">
   <h2>User Account</h2>
   <h3>Welcome <?php echo $user['user_name']; ?>!</h3>
   <div class="account-info">
       <p><b>Name: </b><?php echo $user['user_name']; ?></p>
       <p><b>Email: </b><?php echo $user['user_email']; ?></p>
   </div>
</div>
</body>
</html>

Datenbank:

user:
user_id
user_name
user_password
user_email
user_datetime

Check your Session data first.

PHP Code:

$data['user'] = $this->User_model->getRows(array('id'=>$this->session->userdata('userId')));

var_dump($data);
exit();

// Also try this
var_dump($this->session->userdata());
exit(); 


Do that before you load you view.

What did you Try? What did you Get? What did you Expect?
