Your code seems ok. Are you using global xss. Could it be that the password cause the error? Maybe try with

Code:

$this->db->where(‘user_password’,$this->input->post(‘user_password’),FALSE);

This is not very secure since it leaves the field unprotected.
You should btw use something like

Code:

$this->db->where(‘user_password’,md5($this->input->post(‘user_password’)),FALSE);

or any other encryption, so as not to store the real password in the db and also sanitize through enryption the data.

PS. please use the code tag to place code. [ code] [ /code] without the trailing space after [

If your database passwords are hashed then you need to also hash the user's entered password to compare it to the database password!
