Form Validation Error

I did, and no, you didn't. I don't see any of your callback functions prefixed with underscores to make them private like I stated and the userguide I linked to explains.

Code:

public function is_username_available()

should be

Code:

public function _is_username_available()// prefixed with "_"

which would then also change

Code:

$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean|min_length[6]|max_length[12]|alpha_numeric|strtolower|callback_username_exists');

to

Code:

//extra underscore in 'callback__username'
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean|min_length[6]|max_length[12]|alpha_numeric|strtolower|callback__username_exists');

The same needs to be done for this function and also its rules

Code:

public function is_email_available()
