Through the code below I recover all users logged in to the system and display them in a table.

<?php
        $dados = array(
            'session_id',
            'ip_address',
            'last_activity',
            'user_data'
        );
        $this->db->select($dados);
        $query = $this->db->get("ci_sessions");        
?>

<tbody>
  <?php foreach ($query->result() as $linha):?>
     <tr>
     <?php
    $sessao = $linha->user_data;
    $dados = unserialize($sessao);
     ?>
     <?php if(!empty($dados['nome_usuario'])): ?>
     <td><?php echo htmlspecialchars($dados['nome_usuario'],ENT_QUOTES, 'UTF-8');?></td>
     <td><?php echo htmlspecialchars($linha->ip_address, ENT_QUOTES, 'UTF-8'); ?></td>
     <td><?php echo date('d/m/Y H:i:s',$linha->last_activity);?></td>
     <td><a href="<?php echo site_url('login/deslogar'); ?>" 
          class="btn btn-danger btn-flat">
     <?php echo lang('usuarios_deslogar_usuario'); ?></a></td>
     <?php endif; ?>
     </tr>
  <?php endforeach;?>                                   
</tbody>

What I want now, is to have an option to depress user for each line displayed, that when clicked, user is deprecated.

Through the button:

<td>
  <a href="<?php echo site_url('login/deslogar'); ?>" 
          class="btn btn-danger btn-flat"><?php echo 'Deslogar'; ?>
  </a>
</td>
<?php endif; ?>

So how do I destroy only the session of id that dropped?

php codeigniter

  • I already did that, and did passing the session_id and removing this line from the database, so when this user tried to do any other action on the site he was redirected to the login screen

You need to create a method and delete this user’s record by session_id table ci_sessions:

Html

<td>
  <a href="/login/deslogar/<?php echo $linha->session_id;?>" 
          class="btn btn-danger btn-flat">Deslogar</a>
</td>

Controller

public function deslogar($id)
{
    $this->db->where('session_id', $id);
    $this->db->delete('ci_sessions');   
}

The next action of the user, the same will be directed to login again, this prevents him to work in the last session, but, not in the creation of a new, this can be done also with a field status or active.
