Hey guys,

my problem is the following: I am writing a login library. This library has a function _validation() and this uses the validation library to validate the data. With using normal validation methods it works just fine, but using a callback function just does not work. It is not called.

I call it like this.

$this->CI->form_validation->set_rules('user', 'Username', 'required|callback__check_user');

The functions name is _check_user and it uses the username _check_user($user). The function itself works fine and I can also call it in the class ($this->_check_user('username')) with a working result.

I am guessing, there might be a problem because I am not workin in a controller so I have a CI instance $this->CI instead of just the original instance $this->

Does anyone have a clue how to fix this?

Thanks in advance.
