codeigniter将localhost附加到主页URL以登录页面

Question

Hi guys I am trying to login into my codeigniter project but I am encountering issues such that instead of redirecting to homepage after signin, it appends full url to the signin url as shown below:

http://localhost/prokazi/signin?redirect=http://localhost/prokazi/dashboard

here is the controller that extends all the other controllers.

class Pre_loader extends CI_Controller {

public $login_user;
protected $access_type = "";
protected $allowed_members = array();

function __construct() {
    parent::__construct();
    //$this->load->library('csvimport');
    $this->load->library('Excel');

    //check user's login status, if not logged in redirect to signin page
    $login_user_id = $this->Users_model->login_user_id();
    if (!$login_user_id) {
        $uri_string = uri_string();

        if (!$uri_string || $uri_string === "signin") {
            redirect('signin');
        } else {
            redirect('signin?redirect=' . get_uri($uri_string));
        }
    }

    //initialize login users required information
    $this->login_user = $this->Users_model->get_access_info($login_user_id);

    //initialize login users access permissions
    if ($this->login_user->permissions) {
        $permissions = unserialize($this->login_user->permissions);
        $this->login_user->permissions = is_array($permissions) ? $permissions : array();
    } else {
        $this->login_user->permissions = array();
    }
}
