Try this:

public function insert_into_db()
{
    if( $this->db->insert('reservation', $this->input->post('no_of_poeple', TRUE)) ){
        return TRUE;
    }else{
        return FALSE;
    }
}

Inserting data into the database

Did you have a question to ask other than repeating the title of that two year old post? Best to start a new thread if you do (rather than hijacking an old one) and explain fully what the problem you are having is so that others are in a position to offer some help. Thanks.
