分页CodeIgniter覆盖基本URL

我的网站分页位于"user_area"控制器文件中的"home"函数内。我遵循本页中的示例分页

分页工作正常，除了它打乱了我的base_url。当我点击分页链接，然后点击网站导航栏中的链接时，"home"会被添加到所有链接中。

欢迎任何帮助。

控制器:

    public function home(){
    if($this->session->userdata('is_logged_in')){
        $this->load->model('model_match');
        $this->load->model('model_user');
        $this->load->model('model_msg');    
        $pagination = array();
        $pagination["total_rows"] = $this->model_match->countMatches();
        $pagination["per_page"] = 2;
        $pagination["uri_segment"] = 3;
        $choice = $pagination["total_rows"] / $pagination["per_page"];
        $pagination["num_links"] = round($choice);
        $pagination['base_url'] = base_url('user_area/home');
        $this->pagination->initialize($pagination);
        $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
        $data["videos"] =  $this->model_match->getAllMatches($pagination["per_page"], $page);
        $data["links"] = $this->pagination->create_links();

        $data['count_unread_msgs'] = $this->model_msg->countUnreadMsgs($this->session->userdata('user'));
        $data['count_unread_hearts'] = $this->model_msg->countUnreadHearts($this->session->userdata('user'));

        $data['user_name'] = $this->session->userdata('user');
        //$data['videos'] = $this->model_match->getAllMatches();
        $this->load->view('user/matches',$data);
        }else{
            redirect('home');
            }
    }

导航栏:

        <nav>      

                 <a  href="home">Home</a>   
                  <a  href="message_center">Messages</a>   
                 <a href="account">Account</a>
                   <a   href="library">Portfolio</a>
                 <a   href="favorites">Favorites</a>   
                 <a href="viewer-help.php">Help / FAQ </a> -->
                 <a  href="toolkit">Toolkit</a>   
                   <a href="<?php echo base_url()."login/logout";?>">Logout</a>

                <?php searchOptions();?>
    </nav>
