I am facing a problem. I am using ion_auth library in my CI project and rendering views in bootstrap modal. Anyone please guide me how to pass validation errors to bootstrap modal.
Thanks in advance

How do you send the form?
If ajax, you can return a json and check it.

edit small example:
controller\Modal.php

PHP Code:
<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Modal extends CI_Controller {

    function __construct() {
        parent::__construct();
    }

    public function index() {
        $this->load->view('modal_test');
    }

    public function add() {

        $this->load->helper(array('form', 'url'));

        $this->load->library('form_validation');

        $this->form_validation->set_rules('recipient', 'Recipient', 'required');
        $this->form_validation->set_rules('message', 'Message', 'required');

        $data = array();
        if ($this->form_validation->run() == FALSE) {
            $data = array(
                'code' => 1,
                'msg' => validation_errors()
            );
        } else {
            $data = array(
                'code' => 0,
                'msg' => 'succes'
            );
        }
        
        echo json_encode($data);
    }

} 

view\modal_test.php

PHP Code:
<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
