1.we define form_validation in autoload:-

$autoload['libraries'] = array('database', 'email', 'session','form_validation');

2.we define form in Helper:-

$autoload['helper'] = array('url', 'form');

3.After that we create Controller and load these file:-

1. class Validation extends CI_Controller {
2. public function __construct()
3. {
4. parent::__construct();
5. $this->load->helper(array('form', 'url'));
6. $this->load->libraries('form_validation');
7. }
8. }
9. public function validation_msg()
10. {
11. $this->form_validation->set rules('first name', 'First Name', 'required',
12. $this->form_validation->set rules('second name', 'secondName', 'required',
13. if ($this->form_validation->run() == FALSE)
14. {
15. $this->load->view('formsuccess');
16. }
17. else
18. {
19. echo "Success Message";
20. }
21. }

4.Create a View:-

1. <form action = " " method = "">
2. <?php echo validation_errors(); ?>
3. <h5>First field</h5>
4. <input type = "text" name = "first field" value = "" />
5. <h5>Second field field</h5>
6. <input type = "text" name = "second field" value = "" />
