How to keep url clean on calling $this->index()

I guess the problem is when the credentials are wrong you are stuck in a unwanted url domain.com/index.php/main/validate_user .

And next if you can solve this issue by redirecting using bas_url() the form fields that were filled up were empty.

To overcome this you can use flashdata to set the field values when redirected back.
