In your code

As I see your controller code posted in question, you haven't passed any value in variable $currentID which might be getting undefined, so please first try to var_dump your $currentID variable and check its value.

Do a test

Please try assigning a static id for the sake of functionality. Your static value will be passed to the method as an argument. Once you sure about static value is working, you can go ahead with finding out where is the issue in $currentID variable.

$data['currentID'] = $someValueFromDB;
$this->load->view('some_view.php',$data);

this way your value will be passed to view, make sure value is correctly passing or getting generated on view. You are passing data in right way at controller, no problem with that.

remove the input field. You can't pass any input data with 

<a href="<?=site_url('BookKeeping/update/'.$currentID)?>" class="btn btn-info btn-"><i class="icon-new position-left"></i>Update</a>

Try this 

public function update($id=''){

$session_data = $this->session->userdata('logged_in');
$data['username'] = $session_data['username'];

$id=$id;

echo "<pre>";var_dump($id);
$dc=$this->input->post('dc');
if($dc=='c'){
  $amount=$this->input->post('credit1');
} 
else if ($dc=='d') {
  $amount=$this->input->post('debit');
}

$data=array(
  'date' =>$this->input->post('TDate'),
  'code' =>$this->input->post('TName'),
  'project' =>$this->input->post('TName1'),
  'part' =>$this->input->post('part1'),
  'part1' =>$this->input->post('part2'),
  'dc'=>$this->input->post('dc'),
  'amount'=>$amount,
);

$this->db->where('recno', $id);
$this->db->update('daybook', $data);
$this->session->set_flashdata('Add1', 'Updated Successfully'); 
redirect('BookKeeping/daybook','refresh');

}

you are sending value in url change this

$id=$this->input->post('update');

To

$id=$this->uri->segment('3');
