Instead of being a dick you could of just easily suggested a solution.


The database library has something built in that you aren't taking advantage of yet.

Code:

is_unique[user.id]

This will go the end of your validation rule and can go in replace of your callback function.

Code:

$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]|is_unique[user.id]|xss_clean');
