NEWBIE TO CODE IGNITER any help will be appreciated :)

Answer 1

try
public function update($where, $data){
$this->db->where($where);
$this->db->set($data); //array of new data
$this->db->update($this->table);
return $this->db->affected_rows();
}

Answer 2

Please print your query after the update statement, this will help you to know whether you query is correct or not.
$this->db->last_query();

Answer 3

Please check that query in model
Controller :
$update_id = array();
$update_id['id'] = $this->input->post('id');
$data = array(
'id' => $this->input->post('id'),
'dateReserved' => $this->input->post('dateReserved'),
'requestedBy' => $this->input->post('requestedBy'),
'facility' => $this->input->post('facility'),
'dateFrom' => $this->input->post('dateFrom'),
'dateTo' => $this->input->post('dateTo'),
'timeStart' => $this->input->post('timeStart'),
'timeEnd' => $this->input->post('timeEnd'),
'status' => $this->input->post('status'),
'items' => $this->input->post('items'),
'purpose' => $this->input->post('purpose'),
);
$result = $this->reservation->update('table_name',$update_id, $data);
Model :
$this->db->where($where);
$this->db->update($table, $data);
return $this->db->affected_rows();
