Returning to update form after validation

[eluser]flaky[/eluser]
just make a check if the segment is set

Code:

if($this->uri->segment(4)){
        $query = $this->db->get_where('pp_users', array('userid' => $this->uri->segment(4)));
        
        if ($query->num_rows() == 1)
        {
            $data = $query->row();
        }
    
        return $data;
}
